Nginx的平滑升级 1、查看当前版本 #cd /usr/local/nginx/ #进入Nginx安装目录 # sbin/nginx -V #查看版本 nginx version: nginx/0.7.60 configure arguments: –user=www –group=www –prefix=/usr/local/nginx –with-http_stub_status_module –with-http_ssl_module #编译项 得到原来./configure 的编译项 2.下载最新版 前往查看最新版，http://nginx.org/en/download.html #cd /data/soft/ #wget http://nginx.org/download/nginx-0.8.36.tar.gz #下载 #tar xzvf nginx-0.8.36.tar.gz #解压缩 #cd nginx-0.8.36 3.编译 #./configure –user=www –group=www –prefix=/usr/local/nginx –with-http_stub_status_module –with-http_ssl_module #按原来的选项configure #make #编译 #mv /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx.old #移动旧版本 #cp objs/nginx /usr/local/nginx/sbin/ #复制新版本nginx过去 #cd /usr/local/nginx #sbin/nginx -t #测试下，显示如下就是通过 the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok configuration file /usr/local/nginx/conf/nginx.conf test is successful 4.启动新的，关掉旧的 让nginx把nginx.pid改成nginx.pid.oldbin 跟着启动新的nginx # kill -USR2 `cat /usr/local/nginx/nginx.pid` 退出旧的nignx # kill -QUIT `cat /usr/local/nginx/nginx.pid.oldbin` 5.升级完成。 # sbin/nginx -V nginx version: nginx/0.8.36 TLS SNI support disabled configure arguments: --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module
