Linux(CentOS)环境下安装下载Nginx并配置

时间:2021-08-28 23:12:35

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://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

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。
