docker部署mysql8.0 master slave讀取分離

docker拉取鏡像

docker pull mysql

運行master服務器

docker run -d -e MYSQL_ROOT_PASSWORD=123456 --privileged=true --name masterMysql -v /usr/local/docker/mysql/master/conf:/etc/mysql -v /usr/local/docker/mysql/master/data:/var/lib/mysql -v /usr/local/docker/mysql/master/mysql-files:/var/lib/mysql-files -p 3308:3306 mysql:8.0

運行slave服務器

docker run -d -e MYSQL_ROOT_PASSWORD=123456 --privileged=true --name slaveMysql -v /usr/local/docker/mysql/slave/conf:/etc/mysql -v /usr/local/docker/mysql/slave/data:/var/lib/mysql -v /usr/local/docker/mysql/slave/mysql-files:/var/lib/mysql-files -p 3309:3306 mysql:8.0

配置master mysql

[mysqld]
pid-file        = /var/run/mysqld/mysqld.pid
socket          = /var/run/mysqld/mysqld.sock
datadir         = /var/lib/mysql
secure-file-priv= NULL
server-id = 1
log-bin = master-bin

character-set-server=UTF8MB4
default-storage-engine=INNODB

# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0

# Custom config should go here
!includedir /etc/mysql/conf.d/
[mysql]
default-character-set=UTF8MB4

配置slave mysql

[mysqld]
pid-file        = /var/run/mysqld/mysqld.pid
socket          = /var/run/mysqld/mysqld.sock
datadir         = /var/lib/mysql
secure-file-priv= NULL
server-id = 2
skip-log-bin  # slave關閉命令日誌 減少延時
relay-log = slave-relay-bin
log-slave-updates = 1
read-only = 1
character-set-server=UTF8MB4
default-storage-engine=INNODB

# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0

# Custom config should go here
!includedir /etc/mysql/conf.d/
[mysql]
default-character-set=UTF8MB4

查看並進入容器

docker ps -a
dpcker exec -it masterMysql bash

再開啓個終端運行

docker exec -it slaveMysql bash

進入mysql shell

mysql -uroot -p123456

master服務器執行
