昨天傍晚，接到邮件通知，nginx 开始了其最新的稳定版分支 1.2.x,包含了1.1.x 开发分支的所有特性。

果断更新。下载源码包.
7 wget http://nginx.org/download/nginx-1.2.0.tar.gz

移除旧版本：
[root@PowerPC pub]# rm nginx*
rm: remove regular file `nginx-1.1.19.tar.gz'? y
rm: remove regular file `nginx-1.2.0.tar.gz'? n

解压，进入目录：
我的configure:
[root@PowerPC nginx-1.2.0]# ./configure \
> --prefix=/usr/local/nginx \
> --sbin-path=/usr/local/sbin/nginx \
> --conf-path=/etc/sysconfig/nginx/nginx.conf \

系统给出编译概况：

  nginx path prefix: "/usr/local/nginx"
  nginx binary file: "/usr/local/sbin/nginx"
  nginx configuration prefix: "/etc/sysconfig/nginx"
  nginx configuration file: "/etc/sysconfig/nginx/nginx.conf"

  nginx error log file: "/var/log/nginx/error.log"
  nginx http access log file: "/var/log/nginx/access.log"
  nginx http client request body temporary files: "/tmp/nginx/request"

确认无误后，make && make install 编译安装.

安装完成后，恢复下之前的配置文件。

启动所有服务，至此，升级工作完成。
