docker images

创建挂载目录

mkdir -p /data/mysql/conf
mkdir -p /data/mysql/data
mkdir -p /data/mysql/logs

运行

docker run -p 3306:3306 --name mysql --restart=always --privileged=true \
-v /data/mysql/log:/var/log/mysql \
-v /data/mysql/data:/var/lib/mysql \
-v /data/mysql/conf:/etc/mysql/conf.d \
-v /etc/localtime:/etc/localtime:ro \
-e MYSQL_ROOT_PASSWORD=123456 -d mysql:8.0

创建my.cnf文件，放在 /data/mysql/conf 目录中，注意配置文件中的端口号、字符集、时区

[client]
default-character-set=utf8mb4
[mysql]
default-character-set=utf8mb4
[mysqld]
# 设置东八区时区
default-time_zone = '+8:00'
# 设置密码验证规则，default_authentication_plugin参数已被废弃
# 改为authentication_policy
#default_authentication_plugin=mysql_native_password
authentication_policy=mysql_native_password


#secure_file_priv=/var/lib/mysql
secure_file_priv=
init_connect='SET collation_connection = utf8mb4_0900_ai_ci'
init_connect='SET NAMES utf8mb4'
character-set-server=utf8mb4
collation-server=utf8mb4_0900_ai_ci
skip-character-set-client-handshake
skip-name-resolve
