CentOS安装nginx教程

用putty登录，运行以下命令：

#!/bin/bash

yum -y install gcc gcc-c++ autoconf automake zlib zlib-devel openssl openssl-devel pcre pcre-devel

wget http://nginx.org/download/nginx-1.10.1.tar.gz

tar zxvf nginx-1.10.1.tar.gz
cd nginx-1.10.1
./configure --prefix=/usr/local/nginx
make && make install

service httpd stop
yum -y remove httpd

/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

#设置开机启动
echo "/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf" >> /etc/rc.d/rc.local

Shell安装脚本：

#!/bin/bash

# 配置系统环境
yum install -y gcc gcc-c++ make autoconf automake wget screen iptables sendmail zip unzip perl perl-devel
yum install -y zlib zlib-devel openssl openssl-devel pcre pcre-devel

# 备份配置文件
if [ ! -d 'conf_backup'];then
mkdir 'conf_backup'
fi

if [ -f '/etc/init.d/nginx' ]; then
mv /etc/init.d/nginx ./conf_backup/
fi

if [ -f '/etc/nginx.conf' ]; then
mv /etc/nginx.conf ./conf_backup/
fi

# 检查文件
if [ ! -s 'nginx-1.6.0.tar.gz' ]; then
wget -c http://nginx.org/download/nginx-1.6.0.tar.gz
fi
