docker-compose部署MySQL5.7

不说废话直接上

• 编辑mysql配置

$ vim my.cnf
# 这个配置要挂载进去

[client]
port = 3306
socket = /var/lib/mysql/data/mysql.sock
[mysqld]
 # 针对5.7版本执行group by字句出错问题解决
sql_mode='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION'
 # 一般配置选项
basedir = /var/lib/mysql
datadir = /var/lib/mysql/data
port = 3306
socket = /var/lib/mysql/data/mysql.sock
lc-messages-dir = /usr/share/mysql # 务必配置此项，否则执行sql出错时，只能显示错误代码而不显示具体错误消息
character-set-server=utf8mb4
back_log = 300
max_connections = 3000
max_connect_errors = 50
table_open_cache = 4096
max_allowed_packet = 32M
#binlog_cache_size = 4M
max_heap_table_size = 128M
read_rnd_buffer_size = 16M
sort_buffer_size = 16M
join_buffer_size = 16M
thread_cache_size = 16
query_cache_size = 64M
query_cache_limit = 4M
ft_min_word_len = 8
thread_stack = 512K
#tx_isolation = READ-COMMITTED
tmp_table_size = 64M
#log-bin=mysql-bin
long_query_time = 6
server_id=1
innodb_buffer_pool_size = 1024M
innodb_thread_concurrency = 16
innodb_log_buffer_size = 16M
wait_timeout= 31536000
interactive_timeout= 31536000
lower_case_table_names = 1

• 编辑docker-compose.yml

$ vim docker-compose.yml
# mysql数据要挂载出来，注意自行修改配置目录

version: '3'
services:
  mysql:
    hostname: mysql
    image: mysql:5.7.26
    # network_mode: "host" # 如果需要容器使用宿主机IP(内网IP)，则可以配置此项
    container_name: mysql # 指定容器名称，如果不设置此参数，则由系统自动生成
    restart: unless-stopped # 设置容器自启模式
    command: mysqld
    environment:
      - TZ=Asia/Shanghai # 设置容器时区与宿主机保持一致
      - MYSQL_ROOT_PASSWORD=root # 设置root密码
    volumes:
       # 数据挂载目录自行修改哦！
       - /etc/localtime:/etc/localtime:ro # 设置容器时区与宿主机保持一致
       - /data/mysql/data:/var/lib/mysql/data # 映射数据库保存目录到宿主机，防止数据丢失
       - /data/mysql/my.cnf:/etc/mysql/my.cnf # 映射数据库配置文件

• 启动MySQL5.7

$ docker-compose up -d

• 使用

mysql -uroot -p -h 127.0.0.1
# 输入设置的密码即可
# 默认已给root用户授权，其它用户自行创建并授权
