1.參照官網，安裝docker
2.拉取mysql鏡像（默認拉取最新的鏡像）8.0.11
dockerpullmysql
3.在宿主機創建持久化mysqldata及mysql.cnf
mkdir/usr/local/mysqlData/test/cnf mkdir/usr/local/mysqlData/test/data vi/usr/loal/mysqlData/test/cnf/mysql.cnf
設置本地文件共享：
Docker->Preferences...->FileSharing
4.添加操作權限
chmod777/usr/local/mysqlData/test/data 備注：掛載時權限驗證（操作權限）
5.運行鏡像，設置初始密碼、本機與docker端口的映射與掛載本地數據盤(啟動msyql服務)
dockerrun-itd-p3307:3306--nametest_mysql-v/usr/local/mysqlData/test/conf:/etc/mysql -v/usr/local/mysqlData/test/data:/var/lib/mysql-eMYSQL_ROOT_PASSWORD=123456mysql
運行結果：
6.進入test_mysql容器
Dockerexec-ittest_mysqlbash
如圖：
7.在容器內登錄mysql
8.查看用戶信息
mysql>selectuser,host,authentication_stringfrommysql.user; +------------------+-----------+------------------------------------------------------------------------+ |user|host|authentication_string| +------------------+-----------+------------------------------------------------------------------------+ |root|%|$A$005$7o{'|'AomAw(QvF#.p5wLtCnrG6yX6XQdDVQivGr96POVL.gKnhIAhUhl3.| |mysql.infoschema|localhost|*THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE| |mysql.session|localhost|*THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE| |mysql.sys|localhost|*THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE| |root|localhost|$A$005$0.-%i)H{uYi@zFo7uYF82fYw7DsA93vYLr4uZv6I1tSKao0sbzzcDap3| +------------------+-----------+------------------------------------------------------------------------+ 5rowsinset(0.00sec)
9.設置權限（為root分配權限，以便可以遠程連接）
mysql>grantallPRIVILEGESon*.*toroot@'%'WITHGRANTOPTION; QueryOK,0rowsaffected(0.01sec)
10.由于Mysql5.6以上的版本修改了Password算法，這里需要更新密碼算法，便于使用Navicat連接
mysql>grantallPRIVILEGESon*.*toroot@'%'WITHGRANTOPTION; QueryOK,0rowsaffected(0.01sec) mysql>ALTERuser'root'@'%'IDENTIFIEDBY'123456'PASSWORDEXPIRENEVER; QueryOK,0rowsaffected(0.11sec) mysql>ALTERuser'root'@'%'IDENTIFIEDWITHmysql_native_passwordBY'123456'; QueryOK,0rowsaffected(0.11sec) mysql>FLUSHPRIVILEGES; QueryOK,0rowsaffected(0.01sec)
11.使用navicat連接mysql,如圖：
12.建庫、建表、加數據
查看掛載本地數據盤的內容：
13.測試將容器移除后，數據是否仍然存在
dockerrm-ftest_msyql
容器已經移除了。重新部署test_mysql,參照第5的步驟，進入新容器，訪問數據庫：
xushijiandeiMac:dataxushijian$dockerrun-itd-p3307:3306--nametest_mysql-v/usr/local/mysqlData/test/conf:/etc/mysql-v/usr/local/mysqlData/test/data:/var/lib/mysql-eMYSQL_ROOT_PASSWORD=123456mysql 65b7a60050aaef5765ed055acfd071c7c76f60e85dc25d0e73e0d56eae14aed1 xushijiandeiMac:dataxushijian$dockerexec-ittest_mysqlbash root@65b7a60050aa:/#mysql-uroot-p Enterpassword: WelcometotheMySQLmonitor.Commandsendwith;or\g.

發現數據仍然可以使用，不需要額外的配置，實現了數據的持久化。
阿里云上docker部署MySQL(通過編排模板部署)
<1.配置同第3步類似（只是目錄變化）
master: image:'mysql:latest' environment: -MYSQL_ROOT_PASSWORD=123456 ports: -'3307:3306/tcp' volumes: -'/usr/local/mysqlData/master/conf:/etc/mysql:rw' -'/usr/local/mysqlData/master/data:/var/lib/mysql:rw' labels: aliyun.scale:'1'
<2.如下圖,已部署完成
[root@c13a6d832fd0a49398c62002361d75c60-node1~]#clear [root@c13a6d832fd0a49398c62002361d75c60-node1~]#dockerps CONTAINERIDIMAGECOMMANDCREATEDSTATUSPORTSNAMES 8597b7539a3amysql:latest"docker-entrypoint..."3minutesagoUp3minutes0.0.0.0:3307->3306/tcpmysql_master_1
<3.進入容器，進行權限設置，后續過程參照本機
[root@c13a6d832fd0a49398c62002361d75c60-node1/]#dockerexec-itmysql_master_1bash root@2fc0bbf48941-mysql-master-1:/#mysql-uroot-p Enterpassword: WelcometotheMySQLmonitor.Commandsendwith;or\g.

OracleisaregisteredtrademarkofOracleCorporationand/orits affiliates.Othernamesmaybetrademarksoftheirrespective owners. Type'help;'or'\h'forhelp.Type'\c'toclearthecurrentinputstatement. mysql>
<4.開放3307端口，使得外網可以訪問
云服務器ECS->安全組->選擇所在的地區->配置規則->添加安全組
添加安全組，如圖：
5.外網訪問，如下圖
已連接成功。

主從庫原理分析：
i/o線程去請求主庫的binlog，并將得到的binlog日志寫到relaylog（中繼日志）文件中；主庫會生成一個logdump線程，用來給從庫i/o線程傳binlog；
SQL線程，會讀取relaylog文件中的日志，并解析成具體操作，來實現主從的操作一致，而最終數據一致；
即：從庫IO線程請求->中繼日志->獲取binlog->從庫SQL線程，解析
