Centos安装Nginx

安装说明

系统环境：CentOS-6.3
软件：nginx-1.2.6.tar.gz
安装方式：源码编译安装 
安装位置：/usr/local/nginx 
下载地址：http://nginx.org/en/download.html

安装前提

在安装nginx前，需要确保系统安装了g++、gcc、openssl-devel、pcre-devel和zlib-devel软件。安装必须软件：

[root@admin /]#yum install gcc-c++
yum -y install zlib zlib-devel openssl openssl--devel pcre pcre-devel

检查系统安装的Nginx：

[root@admin local]# find -name nginx
./nginx
./nginx/sbin/nginx
./nginx-1.2.6/objs/nginx

卸载原有的Nginx

[root@admin /]# yum remove nginx

安装

将安装包文件上传到/usr/local中执行以下操作：

[root@admin local]# cd /usr/local
[root@admin local]# tar -zxv -f nginx-1.2.6.tar.gz
[root@admin local]# rm -rf nginx-1.2.6.tar.gz
[root@admin local]# mv nginx-1.2.6 nginx
[root@admin local]# cd /usr/local/nginx
[root@admin nginx]# 

1. ./configure --prefix=/usr/local/nginx --conf-path=/usr/local/nginx/nginx.conf  

[root@admin nginx]# make
[root@admin nginx]# make install

配置

#修改防火墙配置： 
[root@admin nginx-1.2.6]# vi + /etc/sysconfig/iptables
#添加配置项 
-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT
#重启防火墙 
[root@admin nginx-1.2.6]# service iptables restart

启动

#方法1
[root@admin nginx-1.2.6]# /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
#方法2
[root@admin nginx-1.2.6]# cd /usr/local/nginx/sbin
[root@admin sbin]# ./nginx

停止

#查询nginx主进程号 
ps -ef | grep nginx
#停止进程 
kill -QUIT 主进程号 
#快速停止 
kill -TERM 主进程号 
#强制停止 
pkill -9 nginx

重启

[root@admin local]# /usr/local/nginx/sbin/nginx -s reload

出现错误

nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)

nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)

nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)

nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)

nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)

nginx: [emerg] still could not bind()

 

 

解决办法：修改usr/local/nginx/conf/nginx.conf中监听端口80为81，，防火墙中80改为81

，重启

测试

#测试端口 
netstat –na|grep 80
#浏览器中测试 
http://ip:80
