nginx1.18.0平滑升级步骤

文件上传到/urs/local目录下。

nginx-1.18.0.tar.gz

下载链接：http://nginx.org/en/download.html

执行tar zxvf    nginx-1.18.0.tar.gz 解压。

cd /usr/local/nginx-1.18.0
1、查看当前Nginx版本
    [root@test-25 nginx-1.18.0]# /usr/local/nginx/sbin/nginx  -V
    nginx version: nginx/0.7.9
    built by gcc 4.4.6 20120305 (Red Hat 4.4.6-4) (GCC)
    configure arguments: --prefix=/usr/local/nginx

2、配置nginx并编译，切记不要make install
     [root@test-25 nginx-1.18.0]#./configure --prefix=/usr/local/nginx
     [root@test-25 nginx-1.18.0]#make

3、备份原来的nginx文件,使用最新的文件

    先看一下文件日期：
    [root@test-25 nginx-1.18.0]# ll /usr/local/nginx/sbin/nginx
    -rwxr-xr-x 1 root root 2337456 Aug 12  2015 /usr/local/nginx/sbin/nginx

     [root@test-25 nginx-1.18.0]#mv /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx.old

4、使用最新的文件
    [root@test-25 nginx-1.18.0]#cp  /usr/local/nginx-1.18.0/objs/nginx /usr/local/nginx/sbin/nginx
    再看一下文件日期：
    [root@test-25 nginx-1.18.0]#  ll /usr/local/nginx/sbin/nginx
    -rwxr-xr-x 1 root root 3784415 Sep  2 16:31 /usr/local/nginx/sbin/nginx

5、升级nginx（提示正常）
    [root@test-25 nginx-1.18.0]# make upgrade
    /usr/local/nginx/sbin/nginx -t
    nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
    nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
    kill -USR2 `cat /usr/local/nginx/logs/nginx.pid`
    sleep 1
    test -f /usr/local/nginx/logs/nginx.pid.oldbin
    kill -QUIT `cat /usr/local/nginx/logs/nginx.pid.oldbin`

6、查看升级后版本信息（升级成功，且服务不中断）

   [root@test-25 local]#  /usr/local/nginx/sbin/nginx  -V
   nginx version: nginx/1.18.0
   built by gcc 4.4.6 20120305 (Red Hat 4.4.6-4) (GCC)
   configure arguments: --prefix=/usr/local/nginx
