Mysql系列：Mysql5.7 Docker安装

 准备mysql目录
 

mkdir mysql_docker

数据目录
mkdir mysql_docker/mysql_data
日志目录
mkdir mysql_docker/mysql_log

准备mysql配置文件

准备mysql-compose.yml

vim mysql_docker/mysql-compose.yml

    restart: unless-stopped

    volumes:
      - ./my.cnf:/etc/mysql/my.cnf
      - ./mysql_data:/var/lib/mysql
      - ./mysql_log:/var/log/mysql

管理mysql

cd mysql_docker
# 启动
docker-compose -f mysql-compose.yml up -d

# 停止
docker-compose -f mysql-compose.yml stop

docker mysql外网不通问题

查看路由是否打开
sysctl net.ipv4.ip_forward
返回值为1代表路由已开启，为0就是未开启

开启路由
echo 'net.ipv4.ip_forward = 1' >>/etc/sysctl.conf
sysctl -p
sysctl net.ipv4.ip_forward
docker重启mysql
