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.
