3>.对数据库进行安全初始化操作

[[email protected] ~]# mysql_secure_installation 

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

In order to log into MariaDB to secure it, we'll need the current
password for the root user.  If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none): 
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.

Set root password? [Y/n] y
New password: 
Re-enter new password: 
Password updated successfully!
Reloading privilege tables..
 ... Success!


By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them.  This is intended only for testing, and to make the installation
go a bit smoother.  You should remove them before moving into a
production environment.

Remove anonymous users? [Y/n] y
 ... Success!

Normally, root should only be allowed to connect from 'localhost'.  This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] y
 ... Success!

By default, MariaDB comes with a database named 'test' that anyone can
access.  This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n] y
 - Dropping test database...
 ... Success!
 - Removing privileges on test database...
 ... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] y
 ... Success!

Cleaning up...

All done!  If you've completed all of the above steps, your MariaDB
installation should now be secure.

Thanks for using MariaDB!

Summary     : A persistent key-value database
URL         : http://redis.io
License     : BSD
Description : Redis is an advanced key-value store. It is often referred to as a data
            : structure server since keys can contain strings, hashes, lists, sets and
            : sorted sets.
            : 
            : You can run atomic operations on these types, like appending to a string;
            : incrementing the value in a hash; pushing to a list; computing set
            : intersection, union and difference; or getting the member with highest
            : ranking in a sorted set.
            : 
            : In order to achieve its outstanding performance, Redis works with an
            : in-memory dataset. Depending on your use case, you can persist it either
            : by dumping the dataset to disk every once in a while, or by appending
            : each command to a log.
            : 
            : Redis also supports trivial-to-setup master-slave replication, with very
            : fast non-blocking first synchronization, auto-reconnection on net split
            : and so forth.
            : 
            : Other features include Transactions, Pub/Sub, Lua scripting, Keys with a
            : limited time-to-live, and configuration settings to make Redis behave like
            : a cache.
            : 
            : You can use Redis from most programming languages also.

三.配置Nginx支持Mysql和Redis数据库的负载均衡实战

1>.修改nginx的主配置文件

[[email protected] ~]# cat /yinzhengjie/softwares/nginx/conf/nginx.conf
worker_processes  4;
worker_cpu_affinity 00000001 00000010 00000100 00001000; 
 
events {
   worker_connections  100000;
   use epoll;
   accept_mutex on;
   multi_accept on; 
}
 
#加载Nginx支持的TCP反向代理配置文件
include /yinzhengjie/softwares/nginx/conf/tcp/*.conf;
  
http {
     include       mime.types;
       
     default_type  text/html;
    
     server_tokens off; 
      
     charset utf-8;
   
     log_format my_access_json '{"@timestamp":"$time_iso8601",' '"host":"$server_addr",' '"clientip":"$remote_addr",' '"size":$body_bytes_sent,' '"responsetime":$request_ti
me,' '"upstreamtime":"$upstream_response_time",' '"upstreamhost":"$upstream_addr",' '"http_host":"$host",' '"uri":"$uri",' '"domain":"$host",' '"xff":"$http_x_forwarded_for",' '"referer":"$http_referer",' '"tcp_xff":"$proxy_protocol_addr",' '"http_user_agent":"$http_user_agent",' '"status":"$status"}';   
    access_log logs/access_json.log my_access_json;
 
    ssl_certificate /yinzhengjie/softwares/nginx/certs/www.yinzhengjie.org.cn.crt;
    ssl_certificate_key /yinzhengjie/softwares/nginx/certs/www.yinzhengjie.org.cn.key;
    ssl_session_cache shared:sslcache:20m;
    ssl_session_timeout 10m;
  
    include /yinzhengjie/softwares/nginx/conf.d/*.conf;
}
[[email protected] ~]# 
[[email protected] ~]# nginx -t
nginx: the configuration file /yinzhengjie/softwares/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /yinzhengjie/softwares/nginx/conf/nginx.conf test is successful
[[email protected] ~]# 
[[email protected] ~]# 

2>.修改nginx的子配置文件

[[email protected] ~]# cat /yinzhengjie/softwares/nginx/conf/tcp/tcp.conf
stream {
    upstream redis_server {
        server 172.30.1.106:6379 max_fails=3 fail_timeout=30s;
    }

    upstream mysql_server {
        least_conn;
        server 172.30.1.107:3306 max_fails=3 fail_timeout=30s;
    }

    server {
        listen 172.30.1.101:3306;
        proxy_connect_timeout 6s;
        proxy_timeout 15s;
        proxy_pass mysql_server;
    }

    server {
        listen 172.30.1.101:6379;
        proxy_connect_timeout 3s;
        proxy_timeout 3s;
        proxy_pass redis_server;
   }
}
[[email protected] ~]# 
[[email protected] ~]# nginx -t
nginx: the configuration file /yinzhengjie/softwares/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /yinzhengjie/softwares/nginx/conf/nginx.conf test is successful
[[email protected] ~]# 
[[email protected] ~]# 

3>.启动nginx服务

[[email protected] ~]# netstat -untalp | grep nginx
[[email protected] ~]# 
[[email protected] ~]# nginx 　　　　　　　　　　　　　　　　
[[email protected] ~]# 
[[email protected] ~]# netstat -untalp | grep nginx
