Linux(CentOS)环境下安装下载Nginx并配置

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

创建目录(nginx-src)并进去;然后,从官方地址()下载,解压,配置,编译,安装:

  # mkdir nginx-src && cd nginx-src   # wget http://nginxorg/download/nginx-targz   # tar xzf nginx-targz    # cd nginx-3   # /configure   # make   # make install   # whereis nginx   nginx: /usr/local/nginx     

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/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/nginxconf)    -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/nginxpid   # config: /usr/local/nginx/conf/nginxconf      PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin   DESC="nginx deamon"   NAME=nginx   DAEMON=/usr/local/nginx/sbin/$NAME   SCRIPTNAME=/etc/initd/$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: $NAME"    d_start    echo ""   ;;   stop)    echo -n "Stopping $DESC: $NAME"    d_stop    echo ""   ;;   reload)    echo -n "Reloading $DESC conf"    d_reload    echo "reload "   ;;   restart)    echo -n "Restarting $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/initd/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
