容器化部署MySQL5.7数据库

数据持久化

复制代码

# 创建数据目录
data]# ls
mysql  mysql_conf  nginx

# 配置文件 中增加了字符集的配置
data]# cd mysql_conf/
[root@data-visualization-010050101050-security mysql_conf]# ls
my.cnf
[root@data-visualization-010050101050-security mysql_conf]# cat my.cnf 
# For advice on how to change settings please see

[mysqld]
#
# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M
#
# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin
#
# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M

创建容器服务

复制代码

# 创建容器服务，挂载数据文件和配置文件，运行以下命令
docker run -d --restart=always -e LANG=C.UTF-8 -e TZ=Asia/Shanghai -v /data/mysql_conf/my.cnf:/etc/my.cnf -v /data/mysql:/var/lib/mysql --name=mysql_master -p 3306:3306 -e MYSQL_ROOT_PASSWORD=123123 harbor.dazhenyun.cn/repo/mysql:5.7

验证新建的容器化MySQL服务

复制代码

# 进入容器 验证账号密码和字符集配置
bash-4.2# mysql -uroot -p123123
