# Bitnami部署Mysql主从
|
||
|
|
|
||
|
|
1. 创建持久化目录
|
||
|
|
|
||
|
|
```bash
|
||
|
|
mkdir -p /opt/mysql/data
|
||
|
|
chmod 777 /opt/mysql/data
|
||
|
|
```
|
||
|
|
|
||
|
|
2. 部署 Master 容器
|
||
|
|
|
||
|
|
```bash
|
||
|
|
docker run --name mysql-master --restart=always \
|
||
|
|
-p 3306:3306 \
|
||
|
|
-v /opt/mysql/data:/bitnami/mysql/data \
|
||
|
|
-e MYSQL_ROOT_PASSWORD=root \
|
||
|
|
-e MYSQL_REPLICATION_MODE=master \
|
||
|
|
-e MYSQL_REPLICATION_USER=slave \
|
||
|
|
-e MYSQL_REPLICATION_PASSWORD=slave_password \
|
||
|
|
-e MYSQL_AUTHENTICATION_PLUGIN=mysql_native_password \
|
||
|
|
-d bitnami/mysql:latest
|
||
|
|
```
|
||
|
|
|
||
|
|
3. 部署 Slave 容器
|
||
|
|
|
||
|
|
```bash
|
||
|
|
docker run --name mysql-slave --restart=always \
|
||
|
|
-p 3306:3306 \
|
||
|
|
-v /opt/mysql/data:/bitnami/mysql/data \
|
||
|
|
-e MYSQL_MASTER_HOST=<MYSQL_MASTER_HOST> \
|
||
|
|
-e MYSQL_MASTER_ROOT_PASSWORD=root \
|
||
|
|
-e MYSQL_MASTER_PORT_NUMBER=3306 \
|
||
|
|
-e MYSQL_REPLICATION_MODE=slave \
|
||
|
|
-e MYSQL_REPLICATION_USER=slave \
|
||
|
|
-e MYSQL_REPLICATION_PASSWORD=slave_password \
|
||
|
|
-e MYSQL_AUTHENTICATION_PLUGIN=mysql_native_password \
|
||
|
|
-d bitnami/mysql:latest
|
||
|
|
```
|
||
|
|
|
||
|
|
4. 进入 Slave 容器
|
||
|
|
|
||
|
|
```bash
|
||
|
|
docker exec -it mysql-slave bash
|
||
|
|
mysql -u root -proot
|
||
|
|
```
|
||
|
|
|
||
|
|
5. 查看同步状态
|
||
|
|
|
||
|
|
```bash
|
||
|
|
show slave status\G;
|
||
|
|
```
|
||
|
|
|
||

> 切记请勿在主使用清空 GTID 信息命令，会使主从状态失效
