mac 源生安装mysql_docker安装MySQL数据库
本文說明，剛上來使用MySQL高版本的，結果MySQL容器正常運行后，外部客戶端連接不上，最后降低版本就OK
拉取MySQL數據庫鏡像

創建MySQL容器，并后臺啟動
# docker run --name djlmysql -e MYSQL_ROOT_PASSWORD=123456 -p 3307:3306 -d mysql:5.7.22
[root@localhost ~]# docker run --name djlmysql -e MYSQL_ROOT_PASSWORD=123456 -p 3307:3306 -d mysql:5.7.22fa0c44b306c1b5038d39cbe5add1dc05a9f034d21dc1e62bb52487bc8b7ff04f

-e環境變量說明：
MYSQL_ROOT_PASSWORD
本變量必填，它指定了 MySQL?root?的用戶的密碼
MYSQL_DATABASE
本變量可選，通過該變量當 MySQL 啟動時會創建一個由你指定的數據庫。如果你另外又提供了一對用戶名和密碼(見下方)，那么他將會被授予本數據庫的所有權限。
MYSQL_USER,?MYSQL_PASSWORD
這兩個變量可選，同時使用的話會創建一個新用戶并設置相應的密碼，該用戶會被授予由?MYSQL_DATABASE?變量指定的數據庫的所有權限(見上方)。只有當同時提供了這兩個變量時該用戶才會被創建。
特別注意沒有必要使用這個機制來創建 root 用戶，root 用戶的密碼會被設置為?MYSQL_ROOT_PASSWORD?變量的值。
MYSQL_ALLOW_EMPTY_PASSWORD
本變量可選，當其被設置為?yes?時將會允許當前容器中的 root 用戶能夠使用空密碼。注意：絕對不建議將該變量設置為?yes，除非你知道自己在做什么。如果這么做的話你的 MySQL 服務將會失去保護，所有人都可以以超級用戶的身份訪問該 MySQL 服務。
MySQL配置文件的掛載目錄
當 MySQL 服務啟動時會以?/etc/mysql/my.cnf?為配置文件，本文件會導入?/etc/mysql/conf.d?目錄中所有以?.cnf?為后綴的文件。這些文件會拓展或覆蓋?/etc/mysql/my.cnf?文件中的配置。因此你可以創建你自己需要的配置文件并掛載至 MySQL 容器中的?/etc/mysql/conf.d?目錄。
# cat my.cnf
root@70d513b30042:/etc/mysql# ls -l

拷貝源生MySQL配置文件到宿主機
# docker cp djlmysql:/etc/mysql/mysql.conf.d /home/mysqldata/
# docker cp djlmysql:/etc/mysql/conf.d /home/mysqldata/
[root@docker-servers ~]# docker cp djlmysql:/etc/mysql/mysql.conf.d /home/mysqldata/[root@docker-servers ~]#
[root@docker-servers ~]# ls /home/mysqldata/mysql.conf.d
[root@docker-servers ~]#
[root@docker-servers ~]#
[root@docker-servers ~]# docker cp djlmysql:/etc/mysql/conf.d /home/mysqldata/[root@docker-servers ~]#
[root@docker-servers ~]#
[root@docker-servers ~]# ls /home/mysqldata/conf.d mysql.conf.d
MySQL儲存數據的位置(可用于掛載到本地)：/var/lib/mysql
# docker cp djlmysql:/var/lib/mysql /home/mysqldata/
[root@docker-servers ~]# docker cp djlmysql:/var/lib/mysql /home/mysqldata/[root@docker-servers ~]#
[root@docker-servers ~]# ls /home/mysqldata/conf.d mysql mysql.conf.d
[root@docker-servers ~]#
[root@docker-servers ~]# cd /home/mysqldata/mysql
[root@docker-servers mysql]#
[root@docker-servers mysql]# lsauto.cnf ca.pem client-key.pem ibdata1 ib_logfile1 mysql private_key.pem server-cert.pem sys

創建MySQL容器，掛載數據和配置文件到本地
-e TZ="Asia/Shanghai"
# docker run --name mysql -e MYSQL_ROOT_PASSWORD=123456 -p 3306:3306 -v /home/mysqldata/mysql.conf.d:/etc/mysql/mysql.conf.d -v /home/mysqldata/conf.d:/etc/mysql/conf.d -v /home/mysqldata/mysql:/var/lib/mysql -d mysql:5.7.22
