centos7.1 安装 lnmp

centos 7.1 安装 lnmp

1. 安装nginx

   1. 准备安装（安装相应环境）：

   yum -y install gcc-c++ pcre pcre-devel zlib zlib-devel openssl openssl-devel vim
   

   2. 设置vim永久显示行号：vim ~/.vimrc

   set number
   

   1. 配置ssh链接时间：

      1. 服务器端：vim /etc/ssh/ssh_config

      GSSAPIAuthentication no
      ServerAliveInterval 3600
      ServerAliveCountMax 3
      

      2. 客户端：vim /etc/ssh/sshd_config

      ClientAliveInterval 50
      ClientAliveCountMax 3
      

   2. 安装nginx

      1. 检查是否已经安装过nginx如果有，则删除

      find -name nginx
      yum remove nginx
      

      2. 下载nginx、解压缩、编译安装

      wget -c http://nginx.org/download/nginx-1.14.1.tar.gz
      tar -zxvf nginx-1.14.1.tar.gz
      cd nginx-1.14.1
      ./configure
      make -j 4 && make install
      

      3. 安装成功后检查路径whereis nignx，默认在/usr/local/nginx

      4. 安装路径下：/nginx/sbin/nginx -t

      5. 查看进程：ps -ef | grep nginx

      6. 启动，重启，停止：

      命令	说明
      ./nginx	启动
      ./nginx -s reload	重启
      ./nginx -s stop	停止（自动杀死进程）
      ./nginx -s quit	停止

   3. 开放防火墙端口：

      1. 检查防火墙运行状态：systemctl status firewalld
      2. 启动防火墙：systemctl start firewalld
      3. 添加端口：firewall-cmd --zone=public --add-port=80/tcp --permanent
      4. 再次通过systemctl status firewalld查看firewalld状态，显示running即已开启了。

   4. 为域名创建配置：vim /usr/local/nginx/conf/nginx.conf，增加：include vhost/*.conf

   5. 创建nginx启动命令脚本：vim /etc/init.d/nginx

      1. 插入内容

      #! /bin/bash
      # chkconfig: - 85 15
      PATH=/usr/local/nginx
      DESC="nginx daemon"
      NAME=nginx
      DAEMON=$PATH/sbin/$NAME
      CONFIGFILE=$PATH/conf/$NAME.conf
      PIDFILE=$PATH/logs/$NAME.pid
      SCRIPTNAME=/etc/init.d/$NAME
      set -e
      [ -x "$DAEMON" ] || exit 0
      do_start() {
      $DAEMON -c $CONFIGFILE || echo -n "nginx already running"
      }
      do_stop() {
      $DAEMON -s stop || echo -n "nginx not running"
      }
      do_reload() {
      $DAEMON -s reload || echo -n "nginx can't reload"
      }
      case "$1" in
      start)
      echo -n "Starting $DESC: $NAME"
      do_start
      echo "."
      ;;
      stop)
      echo -n "Stopping $DESC: $NAME"
      do_stop
      echo "."
      ;;
      reload|graceful)
      echo -n "Reloading $DESC configuration..."
      do_reload
      echo "."
      ;;
      restart)
      echo -n "Restarting $DESC: $NAME"
      do_stop
      do_start
      echo "."
      ;;
      *)
      echo "Usage: $SCRIPTNAME {start|stop|reload|restart}" >&2
      exit 3
      ;;
      esac
      exit 0
      

      2. 设置执行权限：chmod a+x /etc/init.d/nginx
      3. 注册成服务：chkconfig --add nginx
      4. 设置开机启动：chkconfig nginx on
      5. 重启服务器：shutdown -h 0 -r
      6. 检查是否自动重启：netstat -apn|grep nginx
      7. 针对nginx服务执行命令

      命令	说明
      systemctl start nginx.service	启动
      systemctl stop nginx.service	停止
      systemctl restart nginx.service	重启
      systemctl reload nginx.service	不重启，重新加载配置，直接生效
