nginx 平滑升級tengine

wget  http://tengine.taobao.org/download/tengine-1.5.1.tar.gz //下載Tengine1.5.1版本

tar zxvf tengine-1.5.1.tar.gz //解壓到當前目錄

cd tengine-1.5.1 //進入到目錄

./configure //執行安裝腳本

make //編譯安裝

mv /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx.old //備份nginx的配置文件，路徑參考你本身的

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

#vi /usr/local/nginx/conf/nginx.conf //編輯nginx.conf，刪除以下代碼
#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`
//結束nginx進程

/usr/local/nginx/sbin/nginx -v //查看nginx版本號
返回帶有Tengine版本號等信息則升級成功！

/*
************************************
**卸載Tengine，換回Nginx

*/
rm -rf /usr/local/nginx/sbin/nginx //刪除Tengine配置文件 

mv /usr/local/nginx/sbin/nginx.lod /usr/local/nginx/sbin/nginx  //恢復備份的nginx配置文件，路徑參考你本身的

/etc/init.d/nginx restart //重啓nginx

/usr/local/nginx/sbin/nginx -v //查看nginx版本號
返回帶有Nginx版本號則卸載成功

 

 

實驗以下：

[root@qike tengine-2.1.0]# kill -USR2 `cat /usr/local/nginx/logs/nginx.pid`  //  平滑升級  會在/usr/local/nginx/logs/ 下生成了nginx.pid.oldbin （之前的nginx進程號）  nginx.pid如今變爲tengine的進程號.
