NGINX之linux系统下载安装并配置nginx

来源:互联网 发布:js实现下拉列表 编辑:程序博客网 时间:2024/05/24 01:49

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/NAMESCRIPTNAME=/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 “1instart)echonStartingDESC:DESC:NAMEdstartecho.;;stop)echonStoppingDESC:DESC:NAMEdstopecho.;;reload)echonReloadingDESC 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
