Nginx的平滑升级

1、查看当然版本

cd /usr/local/nginx/ #进入Nginx安装目录
sbin/nginx -V #查看版本
----输出
nginx version: nginx/1.14.0
built by gcc 4.4.7 20120313 (Red Hat 4.4.7-4) (GCC) 
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-1.21.4.tar.gz #下载
tar xzvf nginx-1.21.4.tar.gz #解压缩
cd nginx-1.21.4

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
----输出
the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
configuration file /usr/local/nginx/conf/nginx.conf test is successful

# 或者
mv /usr/local/nginx mv /usr/local/nginx_bak #移动旧版本
./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
make install
cd /usr/local/nginx
sbin/nginx -t #测试下，显示如下就是通过

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`

# 或者 直接重启....
/usr/local/nginx/sbin/nginx -s reload -c /home/zxw/app/nginx/nginx.AH.conf

5.升级完成。

sbin/nginx -V
----输出
nginx version: nginx/1.21.4
built by gcc 4.4.7 20120313 (Red Hat 4.4.7-4) (GCC) 
configure arguments: --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module
