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]#  ./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
