• Centos下快速安装Nginx


    1、准备工作

    选首先安装这几个软件:GCC,PCRE(Perl Compatible Regular Expression),zlib,OpenSSL。

    Nginx是C写的,需要用GCC编译;Nginx的Rewrite和HTTP模块会用到PCRE;Nginx中的Gzip用到zlib;

    用命令“# gcc”,查看gcc是否安装;如果出现“gcc: no input files”信息,说明已经安装好了。

    否则,就需要用命令“# yum install gcc”,进行安装了!一路可能需要多次输入y,进行确认。

    安装好后,可以再用命令“#gcc”测试,或者用命令“# gcc -v”查看其版本号。

    同样方法,用如下命令安装PCRE,zlib,OpenSSL(其中devel,是develop开发包的意思):

    # yum install -y pcre pcre-devel  
    # yum install -y zlib zlib-devel  
    # yum install -y openssl openssl-devel

    2、下载并安装

    一般习惯于在/usr/local/src目录下载安装包,进入目录然后,从官方地址(http://nginx.org/en/download.html)下载,解压,配置,编译,安装:

    # cd /usr/local/src
    # wget http://nginx.org/download/nginx-1.8.1.tar.gz
    # tar xzf nginx-1.8.1.tar.gz
    # cd nginx-1.8.1 
    # ./configure  
    # make  
    # make install

    默认的安装路径为:/usr/local/nginx;跳转到其目录下sbin路径下,便可以启动或停止它了。

    # ./nginx -h  
    nginx version: nginx/1.7.3  
    Usage: nginx [-?hvVtq] [-s signal] [-c filename] [-p prefix] [-g directives]  
    Options:  
      -?,-h         : this help  
      -v            : show version and exit  
      -V            : show version and configure options then exit  
      -t            : test configuration and exit  
      -q            : suppress non-error messages during configuration testing  
      -s signal     : send signal to a master process: stop, quit, reopen, reload  
      -p prefix     : set prefix path (default: /usr/local/nginx/)  
      -c filename   : set configuration file (default: conf/nginx.conf)  
      -g directives : set global directives out of configuration file
    启动:nginx
    停止:nginx -s stop

    3、添加到系统服务

    使用命令“# vi /etc/init.d/nginx”,打开编辑器,输入如下内容:

    #!/bin/sh  
    # chkconfig: 2345 85 15  
    # Startup script for the nginx Web Server  
    # description: nginx is a World Wide Web server.   
    # It is used to serve HTML files and CGI.  
    # processname: nginx  
    # pidfile: /usr/local/nginx/logs/nginx.pid  
    # config: /usr/local/nginx/conf/nginx.conf  
    PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin  
    DESC="nginx deamon"  
    NAME=nginx  
    DAEMON=/usr/local/nginx/sbin/$NAME  
    SCRIPTNAME=/etc/init.d/$NAME  
    test -x $DAEMON || exit 0  
    d_start(){  
      $DAEMON || echo -n "already running"  
    }   
    d_stop(){  
      $DAEMON -s quit || echo -n "not running"  
    }    
    d_reload(){  
      $DAEMON -s reload || echo -n "can not reload"  
    }  
    case "$1" in  
    start)  
      echo -n "Starting DESC:DESC:NAME"  
      d_start  
      echo "."  
    ;;  
    stop)  
      echo -n "Stopping DESC:DESC:NAME"  
      d_stop  
      echo "."  
    ;;  
    reload)  
      echo -n "Reloading $DESC conf..."  
      d_reload  
      echo "reload ."  
    ;;  
    restart)  
      echo -n "Restarting DESC:DESC:NAME"  
      d_stop  
      sleep 2  
      d_start  
      echo "."  
    ;;  
    *)  
      echo "Usage: $ScRIPTNAME {start|stop|reload|restart}" >&2  
      exit 3  
    ;;  
    esac
     exit 0   //保存退出后,再使用下面的命令,使其可执行;然后,添加配置并查看。

    可用chkconfig修改其值,也可用ntsysv工具改变是否自启动。

    # chmod +x /etc/init.d/nginx  
    # chkconfig --add nginx  
    # chkconfig nginx on/off  
    # chkconfig --list nginx  
    nginx 0:off 1:off 2:on 3:on 4:on 5:on 6:off

    ok,访问ip。
