nginx tcp负载均衡的具体实现

mysql负载均衡

安装mysql

yum install -y mariadb-server systemctl start mariadb systemctl enable mariadb ss -ntl

创建数据库并授权

MariaDB [(none)]> create database wordpress; Query OK, 1 row affected (0.00 sec) MariaDB [(none)]> grant all privileges on wordpress .* to “wordpress”@”192.168.33.%” identified by “123456”; Query OK, 0 rows affected (0.00 sec) MariaDB [(none)]> flush privileges; Query OK, 0 rows affected (0.00 sec)

配置nginx

vim /apps/nginx/conf/nginx.conf } stream { upstream mysql_server { server 192.168.33.171:3306 max_fails=3 fail_timeout=30s; } server { listen 192.168.33.180:3306; proxy_connect_timeout 30s; proxy_timeout 300s; proxy_pass mysql_server; } }

写入时闭合http

 访问

redis负载均衡

安装redis

wget https://download.redis.io/releases/redis-6.0.6.tar.gz tar -zxvf redis-6.0.6.tar.gz cd redis-6.0.6 make cd src/ redis-server ss -ntl

修改文件

vim /root/redis-4.0.14/redis.conf 修改为bind 0.0.0.0

配置nginx

stream { upstream mysql_server { server 192.168.33.171:3306 max_fails=3 fail_timeout=30s; server 192.168.33.149:6379 max_fails=3 fail_timeout=30s; } server { listen 192.168.33.180:6379; proxy_connect_timeout 30s; proxy_timeout 300s; proxy_pass mysql_server;} server { listen 192.168.33.180:3306; proxy_connect_timeout 30s; proxy_timeout 300s; proxy_pass mysql_server; } }
