Linux(CentOS)下,下载安装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(http://nginx.org/)下载,解压,配置,编译,安装:

# mkdir nginx-src && cd nginx-src

# wget http://nginx.org/download/nginx-1.7.3.tar.gz
# tar xzf nginx-1.7.3.tar.gz

# cd nginx-1.7.3

# ./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/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
