Nginx连接保持与访问控制

Nginx设置

为何修改Nginx用户与组？

• Nginx运行时进程需要有用户与组的支持，以实现对网站文件读取时进行访问控制

• Nginx默认使用 nobody用户账号与组账号，一般也要进行修改

• 修改的方法

  编译安装时指定用户与组

  修改配置文件时指定用户与组

开启和关闭Nginx

[root@localhost nginx]# cd /usr/local/nginx/
[root@localhost sbin]# nginx   开启nginx
[root@localhost sbin]# killall -s QUIT nginx  关闭进程

查看端口是否开启

[root@localhost nginx]# netstat -ntap | grep 80  查看监听地址
[root@localhost nginx]# yum install -y elinks  检查
[root@localhost sbin]# elinks http://localhost  查看是否开启

安装Nginx服务

[root@localhost ~]# tar zxvf nginx-1.12.2.tar.gz 
[root@localhost ~]#cd /opt
[root@localhost opt]# yum install -y gcc gcc-c++ pcre-devel zlib-devel 
[root@localhost opt]# useradd  -M -s /sbin/nologin nginx 创建用户，组
[root@localhost nginx-1.12.2]# ./configure \     启动脚本
--prefix=/usr/local/nginx \                      配置安装路径         
--user=nginx \                                        指定用户
--group=nginx \                                     指定组
--with-http_stub_status_module             开启统计模块
make && make install
[root@localhost nginx]# cd /usr/local/nginx/
[root@localhost nginx]# ln -s /usr/local/nginx/sbin/nginx /usr/local/sbin/   创建软链接让系统可以识别
[root@localhost sbin]# nginx   开启nginx

开启访问状态统计

[root@localhost nginx]# vim /usr/local/nginx/conf/nginx.conf
        server_name  www.kgc.com;

 47          location /status {       状态统计
 48               stub_status on;      功能开
 49               access_log off ;    访问日志关闭
 50
 51         }

配置named服务

[root@localhost conf]# yum -y install bind


options {
        listen-on port 53 { any; };
        listen-on-v6 port 53 { ::1; };
        directory       "/var/named";
        dump-file       "/var/named/data/cache_dump.db";
        statistics-file "/var/named/data/named_stats.txt";
        memstatistics-file "/var/named/data/named_mem_stats.txt";
        recursing-file  "/var/named/data/named.recursing";
        secroots-file   "/var/named/data/named.secroots";
        allow-query     { any; };

zone "kgc.com" IN {
        type master;
        file "kgc.com.zone";
        allow-update { none; };
};
[root@localhost named]# cp -p named.localhost kgc.com.zone
[root@localhost named]# vim kgc.com.zone 
www  IN   A   192.168.136.10

开启服务

[root@localhost nginx]# iptables -F
[root@localhost nginx]# setenforce 0
[root@localhost nginx]# systemctl stop firewalld
[root@localhost conf] systemctl restart namde
[root@localhost conf]#systemctl nginx restart

授权的访问控制

修改Ngnix配置

[root@localhost nginx]# vim /usr/local/nginx/conf/nginx.conf
43         location / {
 44            auth_basic "secret";
 45             auth_basic_user_file /user/local/nginx/passwd.db；
 

设置用户名和密码

[root@localhost nginx]# yum -y install httpd-tools
[root@localhost nginx]# htpasswd -c /usr/local/nginx/passwd.db zhang   
New password: 
Re-type new password: 
Adding password for user zhang
[root@localhost nginx]# cd /usr/local/nginx/
[root@localhost nginx]# nginx 
[root@localhost nginx]# iptables -F
[root@localhost nginx]# setenforce 0
[root@localhost nginx]# systemctl stop firewalld

[root@localhost nginx]# iptables -F
[root@localhost nginx]# setenforce 0
[root@localhost nginx]# systemctl stop firewalld
