CentOS 安装Nginx

安装所需的软件

1. OpenSSL
   • sudo yum install openssl-devel
2. zlib
   • sudo yum install zlib
3. PCRE
   • sudo yum install pcre-devel
4. gcc && gcc-c++
   • sudo yum install gcc gcc-c++
5. cmake
   • sudo yum install cmake

下载Nginx源码文件

1. site:https://hg.nginx.org/nginx

2. 将下载的Nginx源码上传到服务器中
   • scp nginx.tar-gz user@centos:~/nginx/
3. 解压压缩包
   • tar -xzvf nginx.tar.gz
4. 配置

   ./configure 
   --user=nginx                          
   --group=nginx                         
   --prefix=/etc/nginx                   
   --sbin-path=/usr/sbin/nginx           
   --conf-path=/etc/nginx/nginx.conf     
   --pid-path=/var/run/nginx.pid         
   --lock-path=/var/run/nginx.lock       
   --error-log-path=/var/log/nginx/error.log 
   --http-log-path=/var/log/nginx/access.log 
   --with-http_gzip_static_module        
   --with-http_stub_status_module        
   --with-http_ssl_module                
   --with-pcre                           
   --with-file-aio                       
   --with-http_realip_module             
   --without-http_scgi_module            
   --without-http_uwsgi_module           
   --without-http_fastcgi_module
   

5. 编译文件
   • sudo make
6. 安装文件
   • sudo make install
7. 设置Nginx开机自启动,在/etc/init.d/中创建nginx脚本

   #!/bin/sh
   #
   # nginx - this script starts and stops the nginx daemin
   #
   # chkconfig:   - 85 15
   # description:  Nginx is an HTTP(S) server, HTTP(S) reverse 
   #               proxy and IMAP/POP3 proxy server
   # processname: nginx
   # config:      /etc/nginx/nginx.conf
   # pidfile:     /var/run/nginx.pid
   # user:        nginx
   
   # Source function library.
   . /etc/rc.d/init.d/functions
   
   # Source networking configuration.
   . /etc/sysconfig/network
   
   # Check that networking is up.
   [ "NETWORKING" = "no" ] && exit 0
   
   nginx="/usr/sbin/nginx"
   prog=(basename nginx)
   
   NGINX_CONF_FILE="/etc/nginx/nginx.conf"
   
   lockfile=/var/run/nginx.lock
   
   start() {
       [ -xnginx ] || exit 5
       [ -f NGINX_CONF_FILE ] || exit 6
       echo -n"Starting prog: "
       daemonnginx -c NGINX_CONF_FILE
       retval=?
       echo
       [ retval -eq 0 ] && touchlockfile
       return retval
   }
   
   stop() {
       echo -n"Stopping prog: "
       killprocprog -QUIT
       retval=?
       echo
       [retval -eq 0 ] && rm -f lockfile
       returnretval
   }
   
   restart() {
       configtest || return ?
       stop
       start
   }
   
   reload() {
       configtest || return?
       echo -n "Reloadingprog: "
       killproc nginx -HUP
       RETVAL=?
       echo
   }
   
   force_reload() {
       restart
   }
   
   configtest() {
     nginx -t -cNGINX_CONF_FILE
   }
   
   rh_status() {
       status prog
   }
   
   rh_status_q() {
       rh_status >/dev/null 2>&1
   }
   
   case "1" in
       start)
           rh_status_q && exit 0
           1
           ;;
       stop)
           rh_status_q || exit 01
           ;;
       restart|configtest)
           1
           ;;
       reload)
           rh_status_q || exit 71
           ;;
       force-reload)
           force_reload
           ;;
       status)
           rh_status
           ;;
       condrestart|try-restart)
           rh_status_q || exit 0
               ;;
       *)
           echo "Usage:0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"
           exit 2
   esac
   

8. 设置nginx启动服务
   • sudo chkconfig --add nginx
   • sudo chkconfig --level 345 nginx on
9. 启动nginx服务
   • sudo service nginx start
10. 添加防火墙策略，允许http、https流量
    • sudo firewall-cmd --zone=public --permanent --add-service=http
    • sudo firewall-cmd --zone=public --permanent --add-service=http
    • sudo firewall-cmd --reload
