升级 nginx

*  1、安装配置1.8版本的 nginx
    
      
    
    
    \[root@localhost ~\]\# yum install -y gcc gcc-c++ pcre-devel openssl-devel zlib-devel
    
    \[root@localhost ~\]\# useradd -M -s /sbin/nologin nginx
    
    \[root@localhost ~\]\# tar xf nginx-1.8.1.tar.gz -C /usr/local
    
    \[root@localhost ~\]\# cd /usr/local/nginx-1.8.1/
    
    \[root@localhost nginx-1.8.1\]\# ./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http\_stub\_status\_module
    
      
    
    
    \--prefix=/usr/local/nginx                  \\\\指定安装路径
    
    \--with-http\_stub\_status\_module               \\\\声明启用service status服务状态页,默认 不启用
    
    \--with-http\_ssl\_module                    \\\\启用ssl(Secure Sockets Layer安全套接 层)模块,以支持https请求
    
    \--sbin-path=/usr/bin/                     \\\\声明nginx命令目录

\[root@localhost nginx-1.8.1\]\# make && make install

\[root@localhost nginx-1.8.1\]\# ln -s /usr/local/nginx/sbin/nginx /usr/sbin/

\[root@localhost nginx-1.8.1\]\# nginx

\[root@localhost nginx-1.8.1\]\#  ss -anput | grep nginx

tcp    LISTEN     0      128       \*:80                    \*:\*                   users:    (("ngin",pid=12004,fd=6),("nginx",pid=12003,fd=6))

\[root@localhost nginx-1.8.1\]\# nginx -v

nginx version: nginx/1.8.1

*  2、升级配置nginx-1.10版本      ![blob.png][blob.png 1]

\[root@localhost ~\]\# tar xf nginx-1.10.3.tar.gz -C /usr/local

\[root@localhost ~\]\# cd /usr/local/nginx-1.10.3/

\[root@localhost nginx-1.10.3\]\# ./configure --prefix=/usr/local/nginx --user=nginx --group=ngiinx --with-http\_stub\_status\_module --with-http\_ssl\_module --with-pcre

\[root@localhost nginx-1.10.3\]\# make

\[root@localhost ~\]\# cd

\[root@localhost ~\]\# mv /usr/local/nginx/sbin/nginx  /usr/local/nginx/sbin/nginx\_old

\[root@localhost ~\]\# cp /usr/local/nginx-1.10.3/objs/nginx /usr/local/nginx/sbin/

复制新版本的nginx可执行程序

\[root@localhost ~\]\# mv /usr/local/nginx/conf/nginx.conf /usr/local/nginx/conf/nginx.conf.old

\[root@localhost ~\]\# cp /usr/local/nginx-1.10.3/conf/nginx.conf  /usr/local/nginx/nginx.conf

\[root@localhost ~\]\# kill -USR2 \`cat /usr/local/nginx/logs/nginx.pid\`

主进程将重命名它的 .pid 文件为 .oldbin,然后执行新的可执行程序,依次启动新的主进程和新的工作进程

\[root@localhost ~\]\# ls /usr/local/nginx/logs/

access.log  error.log  nginx.pid

\[root@localhost ~\]\# nginx -v

nginx version: nginx/1.10.3
