• nginx 平滑升级tengine


    wget   //下载Tengine1.5.1版本

    tar zxvf tengine-1.5.1.tar.gz //解压到当前目录

    cd tengine-1.5.1 //进入到目录

    ./configure //执行安装脚本

    make //编译安装

    mv /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx.old //备份nginx的配置文件,路径参考你自己的

    cp -r objs/nginx /usr/local/nginx/sbin/nginx //复制Tengine文件到nginx下

    #vi /usr/local/nginx/conf/nginx.conf //编辑nginx.conf,删除如下代码
    #location /status {
    #stub_status on;
    #access_log off;
    #}

    kill -USR2 `cat /usr/local/nginx/logs/nginx.pid`
    kill -QUIT `cat /usr/local/nginx/logs/nginx.pid.oldbin`
    //结束nginx进程

    /usr/local/nginx/sbin/nginx -v //查看nginx版本号
    返回带有Tengine版本号等信息则升级成功!

    /*
    ************************************
    **卸载Tengine,换回Nginx
    ************************************
    */
    rm -rf /usr/local/nginx/sbin/nginx //删除Tengine配置文件 

    mv /usr/local/nginx/sbin/nginx.lod /usr/local/nginx/sbin/nginx  //恢复备份的nginx配置文件,路径参考你自己的

    /etc/init.d/nginx restart //重启nginx

    /usr/local/nginx/sbin/nginx -v //查看nginx版本号
    返回带有Nginx版本号则卸载成功

    实验如下:

    [root@qike tengine-2.1.0]# kill -USR2 `cat /usr/local/nginx/logs/nginx.pid`  //  平滑升级  会在/usr/local/nginx/logs/ 下生成了nginx.pid.oldbin (以前的nginx进程号)  nginx.pid现在变为tengine的进程号.
