Docker MySQL Cluster installation simulation

A, Docker MySQL Cluster installation simulation

1, download the image

docker pull mysql:5.7

2. Create Master instance and launch

3306 RUN -p Docker: 3306 --name MySQL-Master \ 
-v / mydata / MySQL / Master / log: / var / log / MySQL \ 
-v / mydata / MySQL / Master / Data: / var / lib / MySQL \ 
-v / mydata / MySQL / master / the conf: / etc / MySQL \ 
-e = MYSQL_ROOT_PASSWORD the root \ 
-d MySQL: 5.7 
parameter Description 
 -p 3307: 3306: 3306 mapped to port 3307 of the container port of the host 
 -v / mydata / mysql / master / conf : / etc / mysql: hanging folder configuration to the host 
 -v / mydata / mysql / master / log: / var / log / mysql: log folder mounted to the host 
l -v / mydata / mysql / master / data: / var / lib / mysql /: the host to mount configuration folder 
 -e MYSQL_ROOT_PASSWORD = root: initializing root password

Modify the master configuration file

Modified master basic configuration 
Vim /mydata/mysql/master/conf/my.cnf 

[Client] 
default = UTF8-Character-SET 
 
[MySQL] 
default = UTF8-Character-SET 
 
[mysqld] 
init_connect = '= the SET collation_connection utf8_unicode_ci' 
init_connect = 'the SET NAMES UTF8' 
Character-Server-SET = UTF8 
collation = utf8_unicode_ci-Server 

skip-Character-SET-Client-Handshake 
skip-name-resolve 
# skip DNS 
Note: skip-name-resolve must be added, or connected mysql It will be super slow

Add master primary configuration from the reproducing section 
the server_id =. 1 
log-bin = MySQL-bin 
Read-only = 0 
the binlog-do-DB = gmall_ums 
the binlog-do-DB = gmall_pms 
the binlog-do-DB = gmall_oms 
the binlog-do-DB = gmall_sms 
-do-db = binlog gmall_cms 

replicate the ignore-ignore-db = # MySQL database 
replicate the ignore-db = SYS- 
replicate-the ignore-db = information_schema 
replicate-the ignore-db = performance_schema

3. Create Slave instance and launch

docker run -p 3316:3306 --name mysql-slaver-01 \
-v /mydata/mysql/slaver/log:/var/log/mysql \
-v /mydata/mysql/slaver/data:/var/lib/mysql \
-v /mydata/mysql/slaver/conf:/etc/mysql \
-e MYSQL_ROOT_PASSWORD=root \
-d mysql:5.7

Modify slave configuration files

修改slave基本配置
vim /mydata/mysql/slaver/conf/my.cnf

[client]
default-character-set=utf8
 
[mysql]
default-character-set=utf8
 
[mysqld]
init_connect='SET collation_connection = utf8_unicode_ci'
init_connect='SET NAMES utf8'
character-set-server=utf8
collation-server=utf8_unicode_ci
skip-character-set-client-handshake
skip-name-resolve 

修改slave基本配置
vim /mydata/mysql/slaver/conf/my.cnf

[client]
default-character-set=utf8
 
[mysql]
default-character-set=utf8
 
[mysqld]
init_connect='SET collation_connection = utf8_unicode_ci'
init_connect='SET NAMES utf8'
character-set-server=utf8
collation-server=utf8_unicode_ci
skip-character-set-client-handshake
skip-name-resolve 

4, in order to master his authorized users to synchronize data

1, the container enters the master 
Docker Exec Expediting IT mysql / bin / the bash 

2, into the interior of mysql (mysql -uroot--p) 

   1), root can remotely access authorization (independent from the main, in order to facilitate remote connection we mysql) 
　　　　Grant All privileges ON . * * to 'the root' @ '%' IDENTIFIED by 'the root' with Grant Option; 
　　　　the flush privileges; 
   2), was added to a synchronized user 
       GRANT REPLICATION SLAVE ON * * to ' backup' @ '%' identified by '. 123456 '; 
3, view the status of master 
   show master status \ G;

5, master data synchronization configuration slaver

1, the container enters the slaver 
Docker mysql-slaver Exec Expediting IT-01 / bin / the bash 
2, into the interior of mysql (mysql -uroot--p) 
   1), root can remotely access authorization (independent from the main, in order to facilitate remote connection we mysql) 
　　　  . * * Grant All privileges to ON 'the root' @ '%' IDENTIFIED by 'the root' with Grant Option; 
　　　  the flush privileges; 
   2), set the main database connection 
　　　　change master to master_host = '192.168.159.128' , master_user = 'backup' , master_password = '123456', MASTER_LOG_FILE = 'MySQL-bin.000001', MASTER_LOG_POS = 0, MASTER_PORT = 3307; 
  . 3), starting from the synchronization database 
　　　　start Slave; 
  . 4), from the library to view the state 
     　show slave status \ G;

Thus complete master slave configuration;

to sum up:

         1), master-slave database in its own configuration file statement which needs to be synchronized database, database and other information which is ignored. And server-id can not be the same

         2), the main library authorize an account password to synchronize your data

         3), from the library using the account password to connect the primary repository to synchronize data
