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。
