CentOS下安装Nginx
一、安装Nginx准备:
1、yum -y install pcre* #将所有的pcre安装包安装上,需连网
2、下载nginx安装包
下载地址:http://nginx.org/en/download.html
二、安装:
1、解压nginx-xxx.tar.gz包
命令:tar -xvf nginx-xxx.tar.gz
2、进入解压包
命令:cd nginx-xxx
3、进行安装
命令:./configure --prefix=/usr/local/nginx-1.9 --with-http_stub_status_module
加入--with-http_stub_status_module是为了后面负载做准备
4、修改配置
命令:vim /usr/local/nginx/conf/nginx.conf,修改servername这里的服务器名称,先修改为自己的IP地址
5、启动
命令:/usr/local/nginx/sbin/nginx
6、将防火墙关闭
关闭命令: service iptables stop
永久关闭防火墙:chkconfig iptables off
7、验证结果
在浏览器上输入 http://sername 回车,看是否存在welconme nginx页面,是,表示安装成功
三、配置服务
nginx如果每次用脚本启动,比较麻烦,喜欢使用脚本,所以,特意添加nginx添加到service中的脚本,vim /etc/rc.d/init.d/nginx
该配置代码由官网提供,地址:https://www.nginx.com/resources/wiki/start/topics/examples/redhatnginxinit/
#!/bin/sh # # nginx - this script starts and stops the nginx daemon # # chkconfig: - 85 15 # description: NGINX is an HTTP(S) server, HTTP(S) reverse \ # proxy and IMAP/POP3 proxy server # processname: nginx # config: /etc/nginx/nginx.conf # config: /etc/sysconfig/nginx # pidfile: /var/run/nginx.pid # Source function library. . /etc/rc.d/init.d/functions # Source networking configuration. . /etc/sysconfig/network # Check that networking is up.

二。将shell脚本放入到 /etc/rc.d/init.d/中,并执行下列命令
1:chmod +x /etc/rc.d/init.d/nginx (设置可执行权限)
2:chkconfig --add nginx (添加系统服务)
