Linux系统中Nginx的安装并进行域名认证和重定向
本文主要介绍Linux系统中Nginx的安装并进行域名认证和重定向，希望通过本知识点的讲解对大家今后的学习和工作有所帮助，下面进行具体介绍：
12.6 Nginx安装
cd /usr/local/src
wget http://nginx.org/download/nginx-1.8.0.tar.gz
tar zxvf nginx-1.8.0.tar.gz
./configure --prefix=/usr/local/nginx
make && make install
查看配置文件是否有错 -t
/usr/local/nginx/sbin/nginx -t
启动脚本编辑：
vim /etc/init.d/nginx //复制如下内容(参考https://coding.net/u/aminglinux/p/aminglinux-book/git/blob/master/D15Z/etc_init.d_nginx)
内容为
--------------------------------------------------------------echo#!/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 $NGINX_SBIN -TERM
rm -rf /dev/shm/nginx_temp
RETVAL=$?
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
--------------------------------------------------------------
chmod 755 /etc/init.d/nginx
chkconfig --add nginx
chkconfig nginx on
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)
内容为

}
}
--------------------------------------------------------------
/usr/local/nginx/sbin/nginx -t
/etc/init.d/nginx start
ps aux | grep nginx
netstat -lntp | grep 80
测试#curl localhost
测试php
vim /usr/local/nginx/html/1.php
写入以下内容
----------------------------------------------------------------
echo "This is nginx test page";
----------------------------------------------------------------
测试curl localhost/1.php
12.7 默认虚拟主机
vim /usr/local/nginx/conf/nginx.conf //http里增加下面一行
include vhost/*.conf;
mkdir /usr/local/nginx/conf/vhost
cd !$;vim default.conf //加入如下内容
----------------------------------------------------------------
server
{
listen 80 default_server; //有这个标记的就是默认虚拟主机
server_name aaa.com;
index index.html index.htm index.php;
root /data/wwwroot/default;
}
----------------------------------------------------------------
mkdir -p /data/wwwroot/default
cd /data/wwwroot/default
echo "This is a default site." > /data/wwwroot/default/index.html
/usr/local/nginx/sbin/nginx -t //检查配置是否有错
/usr/local/nginx/sbin/nginx -s reload //重新加载，也可以重启服务
或/etc/init.d/nginx restart //重启服务
curl localhost
curl -x127.0.0.1:80 123.com
12.8 Nginx用户认证
vim /usr/local/nginx/conf/vhost/test.com.conf //写入如下内容
----------------------------------------------------------------
server
{
listen 80 ;
server_name test.com;
index index.html index.htm index.php;
root /data/wwwroot/test.com;
location /
{auth_basic "Auth";
auth_basic_user_file /usr/local/nginx/conf/htpasswd;
}
}
----------------------------------------------------------------
yum install -y httpd
htpasswd -c /usr/local/nginx/conf/htpasswd aming //-c创建
/usr/local/nginx/sbin/nginx -t //检查配置是否有错
/usr/local/nginx/sbin/nginx -s reload //重新加载
curl -x127.0.0.1:80 test.com -I
curl -uaming:lishiming -x127.0.0.1:80 test.com //404错误，-u指定用户；
ls /data/wwwroot/test.com
mkdir /data/wwwroot/test.com
echo "test.com" > /data/wwwroot/test.com/index.html
curl -uaming:lishiming -x127.0.0.1:80 test.com
指定访问admin才认证
curl -uaming:lishiming -x127.0.0.1:80 test.com/admin/
vim /usr/local/nginx/conf/vhost/test.com.conf
将location /修改为location /admin/即可；
curl -x127.0.0.1:80 test.com //就不用指定用户了；
curl -x127.0.0.1:80 test.com/admin/ //提示401用户请求
12.9 Nginx域名重定向
vim /usr/local/nginx/conf/vhost/test.com.conf //修改为如下内容
----------------------------------------------------------------
server
{
listen 80 ;
server_name test.com test1.com test2.com;
index index.html index.htm index.php;
root /data/wwwroot/test.com;
if($host!='test.com'){
rewrite ^/(.*)$ http://test.com/$1 permanent;
}
location ~ admin.php
{auth_basic "Auth";
auth_basic_user_file /usr/local/nginx/conf/htpasswd;
}
}
----------------------------------------------------------------
^表示以某某开头，这里指http://$host
(.*)表示通配所有，$表示直到结尾；
/usr/local/nginx/sbin/nginx -t //检查配置是否有错
/usr/local/nginx/sbin/nginx -s reload //重新加载
curl -x127.0.0.1:80 test2.com/index.html -I //提示301，都重定向到test.com/index.html网页；
