前言

• CentOS 7.9
• Docker Version: 1.13.1

準備

• docker 已安裝。

• 選擇合適的mysql鏡像(mysql:5.7.31)。

拉取鏡像

shell> docker pull mysql:5.7.31 Trying to pull repository docker.io/library/mysql ... 5.7.31: Pulling from docker.io/library/mysql bb79b6b2107f: Pull complete 49e22f6fb9f7: Pull complete 842b1255668c: Pull complete 9f48d1f43000: Pull complete c693f0615bce: Pull complete 8a621b9dbed2: Pull complete 0807d32aef13: Pull complete 6d2fc69dfa35: Pull complete 56153548dd2c: Pull complete 3bb6ba940303: Pull complete 3e1888da91a7: Pull complete Digest: sha256:b3dc8d10307ab7b9ca1a7981b1601a67e176408be618fc4216d137be37dae10b Status: Downloaded newer image for docker.io/mysql:5.7.31 shell> docker images REPOSITORY TAG IMAGE ID CREATED SIZE docker.io/hello-world latest feb5d9fea6a5 6 weeks ago 13.3 kB docker.io/mysql 5.7.31 42cdba9f1b08 12 months ago 448 MB

創建但不運行容器

shell> docker create --restart=always --name mysql1 \ -v /data/mysql1/data:/var/lib/mysql \ -v /data/mysql1/conf.d:/etc/mysql/conf.d \ -e MYSQL_ROOT_PASSWORD=my-secret-pw mysql:5.7.31

• --restart=always： 自動運行
• -v /data/mysql1/data:/var/lib/mysql： 將宿主機的/data/mysql1/data掛載成容器的/var/lib/mysql
• -v /data/mysql1/conf.d:/etc/mysql/conf.d： 將宿主機的/data/mysql1/conf.d掛載成容器的/etc/mysql/conf.d

運行容器

shell> docker start mysql1

命令行登錄mysql

shell> docker exec -it mysql1 bash root@a6f9e4a700a3:/# mysql -uroot -pmy-secret-pw mysql: [Warning] Using a password on the command line interface can be insecure. Welcome to the MySQL monitor.

或者：

shell> docker exec -it mysql1 mysql -uroot -pmy-secret-pw mysql: [Warning] Using a password on the command line interface can be insecure. Welcome to the MySQL monitor. Commands end with ; or \g.

Type '\c' to clear the current input statement.mysql> exit Bye

修改密碼

mysql> set password=password('123456');

mysql 隨 docker 自動啟動

創建容器未添加--restart=always參數時，可以使用docker update添加。

shell> docker update --restart=always mysql1

• 每次docker啟動時，mysql也會自動啟動

設置mysql數據編碼格式為utf8mb4

shell> vim /data/mysql1/conf.d/my.cnf # 打開文件(沒有該文件時，創建它)后，添加下面的配置。注意對應節點 [client] default-character-set = utf8mb4[mysql] default-character-set = utf8mb4[mysqld] character-set-client-handshake = FALSE character-set-server = utf8mb4 collation-server = utf8mb4_unicode_ci init_connect = 'SET NAMES utf8mb4'

設置mysql表名不區分大小寫

shell> vim /data/mysql1/conf.d/my.cnf ----------------------------- # 打開文件后，添加下面的配置。注意對應節點 [mysqld] lower_case_table_names = 1

重啟mysql并查看設置

shell> docker exec -it mysql1 mysql -uroot -p123456 mysql: [Warning] Using a password on the command line interface can be insecure. Welcome to the MySQL monitor. Commands end with ; or \g.
