VPS 折腾全记录-part 4 

好了,值得庆贺的是,本篇是这次中篇连载记录手稿的最后一集了。

:-)

太棒了。

现在就剩下 lighttpd 和 nginx 这两台 http server 了。

先是lighttpd,解压,进入目录:
我的configure:

[root@PowerPC lighttpd-1.4.32]# ./configure \
> --prefix=/opt/lighttpd \
> --disable-lfs \
> --disable-ipv6 \
> --with-mysql=/opt/mysql/bin/mysql_config \
> --with-attr \
> --with-pcre \
> --with-zlib \
> --with-bzip2 \
> --with-fam


检查依赖,没有任何问题。下面是编译程序给出的概况:

Plugins:

mod_access
mod_accesslog
mod_alias
mod_auth
mod_cgi
mod_compress
mod_dirlisting
mod_evhost
mod_expire

mod_simple_vhost
mod_ssi
mod_staticfile

mod_userdir
mod_usertrack
mod_webdav
disabled:
mod_cml
mod_magnet

Features:

regex-conditionals
stat-cache-fam
disabled:
auth-ldap
large-files
network-ipv6
network-openssl
storage-gdbm
storage-memcache
webdav-locks
webdav-properties


确认没有问题后,开始编译,安装。

之后,恢复配置文件。下面问题来了。

尝试启动 lighttpd,出错。

2013-04-23 17:15:11: (plugin.c.169) dlopen() failed for: /opt/lighttpd/lib/mod_mysql_vhost.so libmysqlclient.so.18: cannot open shared object file: No such file or directory
2013-04-23 17:15:11: (server.c.676) loading plugins finally failed


提示找不到mysql 的动态链接库。为啥?因为没有在系统里面注册。因为这次的包括mysql 在内的所有软件都没有使用传统的 /usr/local/ 路径,所以各自.so 文件所在的目录路径,系统自然不知道。
解决方案:
编辑位于 /etc 下的ld.so.conf 文件,加入各自的lib 目录路径。
我的ld.so.conf:

[root@PowerPC src]# cat /etc/ld.so.conf
include ld.so.conf.d/*.conf
/usr/local/lib
/usr/local/libevent/lib
/opt/lighttpd/lib
/opt/mysql/lib


保存之后,ldconfig -v,刷新所有库。
注:这里说点题外话,关于动态链接库的添加,有人建议就像BIN $PATH 一样,追加到系统的 $LD_LIBRARY_PATH 变量里,我个人是不建议这么做的。

再次运行 lighttpd,果然没有问题了。

打印出lighttpd 的版本信息:

[root@PowerPC ~]# lighttpd -V
lighttpd/1.4.32 - a light and fast webserver
Build-Date: Apr 23 2013 16:12:29

Event Handlers:

+ select (generic)
+ poll (Unix)
- rt-signals (Linux 2.4+)
+ epoll (Linux 2.6)
- /dev/poll (Solaris)
- eventports (Solaris)
- kqueue (FreeBSD)
- libev (generic)

Network handler:

+ linux-sendfile
- freebsd-sendfile
- solaris-sendfilev
+ writev
+ write
- mmap support

Features:

- IPv6 support
+ zlib support
+ bzip2 support
+ crypt support
- SSL Support
+ PCRE support
+ mySQL support
- LDAP support
- memcached support
+ FAM support
- LUA support
- xml support
- SQLite support
- GDBM support


搞定了lighttpd,接下来就是 nginx 了,这是剩下的最后一个了。

解压源码,进入源码主目录,
我的configure:

[root@PowerPC nginx-1.3.16]# ./configure \
> --prefix=/opt/nginx \
> --sbin-path=/opt/nginx/sbin/nginx \
> --conf-path=/opt/nginx/etc/nginx.conf \
> --error-log-path=/opt/nginx/var/error.log \
> --pid-path=/opt/nginx/var/nginx.pid \
> --lock-path=/opt/nginx/var/nginx.lock \
> --user=http \
> --group=web \

> --with-file-aio \
> --with-http_spdy_module \
> --with-http_realip_module \
> --with-http_addition_module \
> --with-http_image_filter_module \
> --with-http_flv_module \
> --with-http_mp4_module \
> --with-http_gunzip_module \
> --with-http_gzip_static_module \
> --without-http_fastcgi_module \

> --http-proxy-temp-path=/tmp/nginx/proxy \
> --without-mail_pop3_module \
> --without-mail_imap_module \
> --without-mail_smtp_module


检查依赖,一次通过。同样,和lighttpd 一样,编译程序给出了编译概况,见下:

Configuration summary
+ using system PCRE library
+ OpenSSL library is not used
+ md5: using system crypto library
+ sha1: using system crypto library
+ using system zlib library

nginx path prefix: "/opt/nginx"
nginx binary file: "/opt/nginx/sbin/nginx"
nginx configuration prefix: "/opt/nginx/etc"
nginx configuration file: "/opt/nginx/etc/nginx.conf"
nginx pid file: "/opt/nginx/var/nginx.pid"
nginx error log file: "/opt/nginx/var/error.log"
nginx http access log file: "/opt/nginx/var/access.log"
nginx http client request body temporary files: "/tmp/nginx/request"
nginx http proxy temporary files: "/tmp/nginx/proxy"


确认没有问题,make && make install 开始编译和安装。
一切都很顺利。在最后别忘了恢复下配置文件。
主要就是个 nginx.conf 文件。

好了,至此,这次的VPS升级、折腾手记全文完。

谢谢观赏。:)

VPS 折腾全记录-part 3 

接上。

搞完了底层基础(db 和 runtime),还是搞上层软件(ftp 、http 、cache server).

先是vsftpd,解压,进入目录:
首先编辑 builddefs.h,选择一些特性(如tcp wrapper)的开与关。

接下来直接make 编译,一般来讲几乎不会有问题,如果出错,那就是bug.

编译完成,安装。

[root@PowerPC vsftpd-3.0.2]# make install
if [ -x /usr/local/sbin ]; then \
install -m 755 vsftpd /usr/local/sbin/vsftpd; \
else \
install -m 755 vsftpd /usr/sbin/vsftpd; fi
if [ -x /usr/local/man ]; then \
install -m 644 vsftpd.8 /usr/local/man/man8/vsftpd.8; \
install -m 644 vsftpd.conf.5 /usr/local/man/man5/vsftpd.conf.5; \
elif [ -x /usr/share/man ]; then \
install -m 644 vsftpd.8 /usr/share/man/man8/vsftpd.8; \
install -m 644 vsftpd.conf.5 /usr/share/man/man5/vsftpd.conf.5; \
else \
install -m 644 vsftpd.8 /usr/man/man8/vsftpd.8; \
install -m 644 vsftpd.conf.5 /usr/man/man5/vsftpd.conf.5; fi
if [ -x /etc/xinetd.d ]; then \
install -m 644 xinetd.d/vsftpd /etc/xinetd.d/vsftpd; fi


就是一些启动脚本,执行主程序文件,手册。如果不使用 make install ,也可以手动复制。

接下来就是恢复配置文件 vsftpd.conf.

按说,因为我的vsftpd 是用pam_mysql 认证去做虚拟用户管理。本来我是打算重新编译一个pam_mysql.so 的,因为平时,每次,只要我安装了新的mysql 后都会这么做,因为之前的适用于之前版本的pam_mysql.so 不能用了。

可是,这次,很惊奇的是,给 mysql 5.6.8 的pam_mysql.so 居然可以用,呵呵。这倒给我省事了。

然而,问题还是有的。当我启动了vsftpd 后,我发现我的用户登录后出现了一个500错误:

vsftpd: refusing to run with writable root inside chroot()


经查,这是新版本的vsftpd 的一个新特性,及不允许虚拟用户的主根目录具有可写权限。

庆幸的是,这是可以关闭的。我在这里这里找到了答案。
参见:http://askubuntu.com/questions/239239/ubuntu-12-04-500-oops-vsftpd-refusing-to-run-with-writable-root-inside-chroot

修改后 vsftpd.conf 就像这样:

[root@PowerPC ~]# cat /etc/vsftpd.conf | grep chroot
# You may specify an explicit list of local users to chroot() to their home
# directory. If chroot_local_user is YES, then this list becomes a list of
# users to NOT chroot().
chroot_local_user=NO
chroot_list_enable=YES
chroot_list_file=/etc/vsftpd/ftpusers
allow_writeable_chroot=YES


请注意最后一行,是它禁用了这一安全检查。

这下,vsftpd 又可以像从前一样自由登入登出了。

搞定了ftp 服务器,现在轮到代理、缓存服务器了。

一样,解压varnish源码包,进入根目录:
我的configure:

[root@PowerPC varnish-3.0.3]# ./configure \
> --prefix=/opt/varnish \
> --disable-largefile \
> --enable-epoll \
> --with-pcre-config=/usr/bin/pcre-config \
> --with-jemalloc


检查编译,通过,开始编译安装。

一切都很顺利。

最后,别忘了恢复配置文件 default.vcl.

好了,缓存服务器也搞定了。

未完待续。

VPS 折腾全记录-part 2 

接上文。

搞定了mysql,接下来是php.

我选择的是最新版的php 5.5 beta,解压,进入目录:

我的configure:

[root@PowerPC php-5.5.0beta3]# ./configure \
> --prefix=/opt/php \
> --disable-cli \
> --enable-fpm \
> --with-fpm-user=http \
> --with-fpm-group=web \
> --with-config-file-scan-dir=/etc \
> --disable-ipv6 \ (remove later)
> --with-zlib \
> --with-bz2 \
> --enable-calendar \
> --with-curl \
> --enable-dba \
> --enable-exif \
> --enable-ftp \
> --with-gd \
> --with-mhash \
> --enable-intl \ (remove later)
> --enable-mbstring \
> --with-mcrypt \
> --with-mysql=/opt/mysql \
> --with-mysql-sock=/tmp/mysql.sock \
> --with-mysqli=/opt/mysql/bin/mysql_config \
> --with-pdo-mysql=/opt/mysql \
> --enable-soap \
> --enable-sockets \
> --enable-wddx \
> --with-xmlrpc \
> --enable-zip \
> --without-pear


检查依赖,报错,提示:

configure: error: ICU version 4.0 or later is required


可是我vps的 centos 4 源里面的ICU 库版本是3.x的。故而放弃启用 "--enable-intl".

之后依赖没有问题,开始编译。报错:

ext/sockets/.libs/conversions.o: In function `from_zval_write_sin6_addr':
/root/php-5.5.0beta3/ext/sockets/conversions.c:610: undefined reference to `php_set_inet6_addr'
collect2: ld returned 1 exit status
make: *** [sapi/fpm/php-fpm] Error 1


经查,这是php 5.5 的一个已知bug,在php 5.3.x 上没有复现。移除显式的禁用ipv6 的 “--disable-ipv6” 后,再次编译通过。

编译完毕,安装。


[root@PowerPC php-5.5.0beta3]# make install

Installing PHP CGI binary: /opt/php/bin/
cp: cannot create regular file `/opt/php/bin/#INST@11313#': No such file or directory
make: *** [install-cgi] Error 1


继续出错,从日志可以看出,创建 bin 目录出错。经查,这也是php的一个已知bug.在没有指定 bin/sbin 的具体路径时会触发。
参见:https://bugs.php.net/bug.php?id=61345

解决方案,手动创建即可。


[root@PowerPC php-5.5.0beta3]# mkdir /opt/php/bin

[root@PowerPC php-5.5.0beta3]# make install
/bin/sh /root/php-5.5.0beta3/libtool --silent --preserve-dup-deps --mode=install cp ext/opcache/opcache.la /root/php-5.5.0beta3/modules

至此,php 安装完毕。

可是还没完,还得为其安装 APC 模块。

我使用的是php apc 官方最新的版本,3.1.13。解压,进入目录:

首先运行 phpize,生成 configure 文件.

[root@PowerPC APC-3.1.13]# phpize
Configuring for:
PHP Api Version: 20121113
Zend Module Api No: 20121212
Zend Extension Api No: 220121212


下面开始编译,我的configure:

[root@PowerPC APC-3.1.13]# ./configure \
> --enable-apc \
> --enable-apc-filehits \
> --with-php-config=/opt/php/bin/php-config


依赖没问题,开始编译。出错,日志如下:

/root/APC-3.1.13/apc_compile.c: In function ‘apc_copy_trait_alias’:
/root/APC-3.1.13/apc_compile.c:2379: error: ‘zend_trait_alias’ has no member named ‘function’
/root/APC-3.1.13/apc_compile.c:2380: error: ‘zend_trait_alias’ has no member named ‘function’
/root/APC-3.1.13/apc_compile.c:2380: error: ‘zend_trait_alias’ has no member named ‘function’

/root/APC-3.1.13/apc_compile.c:2417: error: ‘zend_trait_precedence’ has no member named ‘function’
make: *** [apc_compile.lo] Error 1

搜索无果,没有找到与此相关的任何有用信息。无奈,只好认为是此版本的固有bug。只好使用最新的开发版本试试看。

签出APC 位于 SVN 代码库的最新版本:
svn co http://svn.php.net/repository/pecl/apc/trunk apc

重复之前的步骤,编译通过。囧~看来真是这样。
开始安装插件至php:

[root@PowerPC apc]# make install
Installing shared extensions: /opt/php/lib/php/extensions/no-debug-non-zts-20121212/
Installing header files: /opt/php/include/php/


这时,记得恢复下之前备份的配置文件,php.ini 和 php-fpm.conf 。

打印下php的版本和模块信息,以做参照。

VPS 折腾全记录-part 1 

是的,在犹豫、彷徨、挣扎了那么那么久之后,我终于狠下心来,抽出了几天的时间,把早就该升级的VPS从里到外翻新了一遍。

前言:由于整体篇幅较大,所以采用了分段发表,此文为第一部分。
又及:前几天刚刚发生了四川芦山特大地震,在此向死难者致哀。

下面正文开始,首先下载升级所需的所有软件的最新版本:

20 wget http://pecl.php.net/get/APC-3.1.13.tgz
22 wget http://download.lighttpd.net/lighttpd/r ... 32.tar.bz2
24 wget http://cdn.mysql.com/Downloads/MySQL-5. ... .10.tar.gz
26 wget http://nginx.org/download/nginx-1.3.15.tar.gz
28 wget http://downloads.php.net/dsp/php-5.5.0beta3.tar.bz2
30 wget http://repo.varnish-cache.org/source/va ... 0.3.tar.gz
32 wget https://security.appspot.com/downloads/vsftpd-3.0.2.tar.gz


后来有一些软件,如nginx,在我下载后的几个小时里,又发布了新版,后来使用了新版。

移除旧软件包:

[root@PowerPC pub]# rm APC*
rm: remove regular file `APC-3.1.10.tgz'? y
rm: remove regular file `APC-3.1.13.tgz'? n
[root@PowerPC pub]# rm lighttpd*
rm: remove regular file `lighttpd-1.4.31.tar.bz2'? y
rm: remove regular file `lighttpd-1.4.32.tar.bz2'? n
[root@PowerPC pub]# rm mysql*
rm: remove regular file `mysql-5.6.10.tar.gz'? n
rm: remove regular file `mysql-5.6.5-m8.tar.gz'? y
[root@PowerPC pub]# rm nginx*
rm: remove regular file `nginx-1.3.15.tar.gz'? n
rm: remove regular file `nginx-1.3.1.tar.gz'? y
[root@PowerPC pub]# rm php*
rm: remove regular file `php-5.4.0.tar.bz2'? y
rm: remove regular file `php-5.5.0beta3.tar.bz2'? n
rm: remove regular file `phpMyAdmin-3.5.1-all-languages.tar.bz2'? n
[root@PowerPC pub]# rm varnish*
rm: remove regular file `varnish-3.0.3-rc1.tar.gz'? y
rm: remove regular file `varnish-3.0.3.tar.gz'? n
[root@PowerPC pub]# rm vsftpd*
rm: remove regular file `vsftpd-2.3.4.tar.gz'? y
rm: remove regular file `vsftpd-3.0.2.tar.gz'? n


紧接着,移除老版本软件的遗留文件,备份配置文件。

备份数据库:

mysql> show databases;

| bbpress |
| lighttpd |
| phpbb |
| typecho |
| url-shortize |
| vsftpd |

9 rows in set (0.00 sec)


我是用 mysqldump 导出来的几个数据库。

一些前期工作搞定后,开始折腾,先是数据库:

使用的是mysql 的最新版,5.6.11,解压源码包,进入根目录:

首先查看下编译帮助:

[root@PowerPC mysql-5.6.11]# cmake -LAH
-- Running cmake version 2.6.4
-- MySQL 5.6.11
-- Packaging as: mysql-5.6.11-Linux-i686

-- Library mysqlserver depends on OSLIBS -lpthread;m;rt;crypt;dl;aio
-- Configuring done
-- Generating done
-- Build files have been written to: /root/mysql-5.6.11
……
……


下面是我的cmake 参数:

[root@PowerPC mysql-5.6.11]# cmake . \
> -DCMAKE_BUILD_TYPE:STRING=Release \
> -DCMAKE_INSTALL_PREFIX:PATH=/opt/mysql \
> -DENABLE_DEBUG_SYNC:BOOL=OFF \
> -DMANUFACTURER:STRING="Built from Source By Sharl" \
> -DMYSQL_DATADIR:PATH=/var/mysql \
> -DSYSCONFDIR:PATH=/etc


依赖没有问题,开始编译。make && make install.

安装至指定目录后,由于这次使用的目录不在/usr/local 下,所以mysql 的bin 目录并不在系统 $PATH 下,得手动加入。

建议放入 ~/.bashrc 下,编辑完记得 source 以生效.

这是我的 .bashrc:

[root@PowerPC ~]# cat ~/.bashrc | grep PATH
export PATH=/opt/mysql/bin:$PATH
export PATH=/opt/php/bin:$PATH
export PATH=/opt/php/sbin:$PATH
export PATH=/opt/lighttpd/sbin:$PATH
export PATH=/opt/nginx/sbin:$PATH
export PATH=/opt/varnish/bin:$PATH
export PATH=/opt/varnish/sbin:$PATH


进入mysql主目录,安装初始数据库:

[root@PowerPC mysql]# ./scripts/mysql_install_db \
> --basedir=/opt/mysql \
> --datadir=/var/mysql \
> --user=mysql


之后,恢复配置文件,启动mysql服务。

[root@PowerPC mysql]# mysqld_safe --user=mysql &
[1] 30283


设置root密码以及匿名安全选项:

[root@PowerPC mysql]# mysql_secure_installation



NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!

In order to log into MySQL to secure it, we'll need the current
password for the root user. If you've just installed MySQL, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none):
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MySQL
root user without the proper authorisation.

Set root password? [Y/n] y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
... Success!


By default, a MySQL installation has an anonymous user, allowing anyone
to log into MySQL without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.

Remove anonymous users? [Y/n] y
... Success!

Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] y
... Success!

By default, MySQL comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n] y
- Dropping test database...
... Success!
- Removing privileges on test database...
... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] y
... Success!




All done! If you've completed all of the above steps, your MySQL
installation should now be secure.

Thanks for using MySQL!


Cleaning up...



一切OK后,导入之前备份的数据库:

[root@PowerPC ~]# mysql -u root -p <db.sql
Enter password:
[root@PowerPC ~]# mysql -u root -p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.

OK,数据库导入成功。不过还要做一点小优化,就是禁用掉innoDB引擎,因为这个太占内存了。

编辑my.cnf,加入 skip-innodb 节点即可。

现在查看下数据库引擎:

OK,已经禁用了。

至此,mysql 升级完成。

linux 内核升级后导致的Oracle VM 虚拟机无法启动 

这个情况可能很多人都遇到了,因为在GNU/Linux 上升级linux kernel 是家常便饭的事情。

由于我所使用的是virtualbox.org 官方源上提供的闭源版本,所以不清楚这种情况会不会出现在发行版自带的vbox 版本上,如 packages.ubuntu.com 上的 virtualbox open source edition.

好了,开始说正事。

就是当GNU/Linux 系统更换了内核后,导致了vbox 所需要的ddms 以及虚拟内核模块需要重新编译一个适用于当前新内核的。

而升级内核默认是不会安装新内核的头文件包的,也就是 linux-headers-x.x.x-xx-generic。

所以,使用了新内核的虚拟机自然是不会启动的。

解决办法:安装内核对应的头文件包。


sudo apt-get install linux-headers-`uname -r`

sharl@sharl-desktop:~$ sudo /etc/init.d/vboxdrv setup
* Stopping VirtualBox kernel modules [ OK ]
* Recompiling VirtualBox kernel modules [ OK ]
* Starting VirtualBox kernel modules [ OK ]


再次启动虚拟机,OK,问题解决。

附完整的内核安装包列表:

sharl@sharl-desktop:~$ dpkg -l | grep `uname -r`
ii linux-headers-3.5.0-27-generic 3.5.0-27.46 amd64 Linux kernel headers for version 3.5.0 on 64 bit x86 SMP
ii linux-image-3.5.0-27-generic 3.5.0-27.46 amd64 Linux kernel image for version 3.5.0 on 64 bit x86 SMP
ii linux-image-extra-3.5.0-27-generic 3.5.0-27.46 amd64 Linux kernel image for version 3.5.0 on 64 bit x86 SMP
sharl@sharl-desktop:~$
