1. 安装Nginx

cd /usr/local/src
wget http://nginx.org/download/nginx-1.12.2.tar.gz
tar zxf nginx-1.12.2.tar.gz
cd nginx-1.12.2
./configure --prefix=/usr/local/nginx
make && make install

yum install -y gcc pcre-devel zlib-devel

编辑启动脚本

vim /etc/init.d/nginx

粘贴以下内容
https://coding.net/u/aminglinux/p/aminglinux-book/git/blob/master/D15Z/etc_init.d_nginx

#!/bin/bash
# chkconfig: - 30 21
# description: http service.
# Source Function Library
. /etc/init.d/functions
# Nginx Settings

NGINX_SBIN="/usr/local/nginx/sbin/nginx"
NGINX_CONF="/usr/local/nginx/conf/nginx.conf"
NGINX_PID="/usr/local/nginx/logs/nginx.pid"
RETVAL=0
prog="Nginx"

start() 
{
    echo -n $"Starting $prog: "
    mkdir -p /dev/shm/nginx_temp
    daemon $NGINX_SBIN -c $NGINX_CONF
    RETVAL=$?
    echo
    return $RETVAL
}

stop() 
{
    echo -n $"Stopping $prog: "
    killproc -p $NGINX_PID $NGINX_SBIN -TERM
    rm -rf /dev/shm/nginx_temp
    RETVAL=$?
    echo
    return $RETVAL
}

reload()
{
    echo -n $"Reloading $prog: "
    killproc -p $NGINX_PID $NGINX_SBIN -HUP
    RETVAL=$?
    echo
    return $RETVAL
}

restart()
{
    stop
    start
}

configtest()
{
    $NGINX_SBIN -c $NGINX_CONF -t
    return 0
}

case "$1" in
  start)
        start
        ;;
  stop)
        stop
        ;;
  reload)
        reload
        ;;
  restart)
        restart
        ;;
  configtest)
        configtest
        ;;
  *)
        echo $"Usage: $0 {start|stop|reload|restart|configtest}"
        RETVAL=1
esac

exit $RETVAL

修改权限, 加入开机启动

chmod 755 /etc/init.d/nginx
chkconfig --add nginx 
chkconfig nginx on 

编辑配置文件

cd /usr/local/nginx/conf/; mv nginx.conf nginx.conf.bak
vim nginx.conf
写入如下内容
参考https://coding.net/u/aminglinux/p/aminglinux-book/git/blob/master/D15Z/nginx.conf

    {
        listen 80;
        server_name localhost;
        index index.html index.htm index.php;
        root /usr/local/nginx/html;

        location ~ \.php$ 
        {
            include fastcgi_params;
            fastcgi_pass unix:/tmp/php-fcgi.sock;
            fastcgi_index index.php;
            fastcgi_param SCRIPT_FILENAME /usr/local/nginx/html$fastcgi_script_name;
        }    
    }
}

测试

/usr/local/nginx/sbin/nginx -t
/etc/init.d/nginx start
netstat -lntp |grep 80

2. 默认虚拟主机

编辑配置文件
vim /usr/local/nginx/conf/nginx.conf

引入vhost文件夹下的所有配置文件
在最后一个}上面加入include vhost/*.conf;

创建vhost目录
mkdir /usr/local/nginx/conf/vhost

编辑配置文件
cd !$; vim default.conf
加入如下内容

server
{
    listen 80 default_server;  #有这个标记的就是默认虚拟主机
    server_name aaa.com;
    index index.html index.htm index.php;
    root /data/wwwroot/default;
}

mkdir -p /data/wwwroot/default/
echo “This is a default site.”>/data/wwwroot/default/index.html

测试, 重新加载
/usr/local/nginx/sbin/nginx -t
/usr/local/nginx/sbin/nginx -s reload
curl localhost
curl -x127.0.0.1:80 123.com

3. Nginx用户认证

编辑配置文件
vim /usr/local/nginx/conf/vhost/test.com.conf
写入如下内容

server
{
    listen 80;
    server_name test.com;
    index index.html index.htm index.php;
    root /data/wwwroot/test.com;

    location  / 
    {
        auth_basic              "Auth";
        auth_basic_user_file  /usr/local/nginx/conf/htpasswd;
    }
}

yum install -y httpd
htpasswd -c /usr/local/nginx/conf/htpasswd aming

已安装用这个:
/usr/local/apache2.4/bin/htpasswd /usr/local/nginx/conf/htpasswd 1111

测试配置并重新加载
/usr/local/nginx/sbin/nginx -t
/usr/local/nginx/sbin/nginx -s reload

curl -x127.0.0.1:80 test.com
curl -uaming:aming -x127.0.0.1:80 test.com

mkdir /data/wwwroot/test.com
echo "hello world test.com" > /data/wwwroot/test.com/index.html

限制单个目录, 改成 location /admin/
匹配: location ~ admin.phplocation ~(.*)admin.php$

4. Nginx域名重定向

编辑配置文件
vim /usr/local/nginx/conf/vhost/test.com.conf

server
{
    listen 80;
    server_name test.com test1.com test2.com;
    index index.html index.htm index.php;
    root /data/wwwroot/test.com;
    if ($host != 'test.com' ) {
        rewrite  ^/(.*)$  http://test.com/$1  permanent;
    }
}

server_name后面支持写多个域名,这里要和httpd的做一个对比
permanent为永久重定向,状态码为301,如果写redirect则为302
