mysql innodb cluster服务器搭建

一、限于环境，只有2台服务器，一台安装mysql + mysqlrouter，另外一台安装2个mysql实例；

二、添加2台服务器的/etc/hosts文件，以下：

192.168.1.223  dbserver01
192.168.1.224  dbserver02

三、准备安装包文件：

mysql-router-2.1.4-linux-glibc2.12-x86-64bit.tar.gz
mysql-shell-1.0.10-linux-glibc2.12-x86-64bit.tar.gz
mysql-5.7.20-linux-glibc2.12-x86_64.tar.gz

四、解压安装包到相应目录如：/test/mysql-3306，在/test/mysql-3306目录下建立data、log目录，建立my.cnf文件

my.cnf文件内容：

[mysqld]
port = 3306
socket=/test/mysql-3306/mysql.sock
basedir=/test/mysql-3306
datadir=/test/mysql-3306/data
log-error=/test/mysql-3306/log/mysql.log
pid-file=/test/mysql-3306/mysql.pid

# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0

[mysqld_safe]
port = 3306
socket=/test/mysql-3306/mysql.sock
basedir=/test/mysql-3306
datadir=/test/mysql-3306/data
log-error=/test/mysql-3306/log/mysql.log
pid-file=/test/mysql-3306/mysql.pid


[mysql]
port = 3306
socket=/test/mysql-3306/mysql.sock


[mysqladmin]
port = 3306
socket=/test/mysql-3306/mysql.sock

五、拷贝init_3306.sh、login_3306.sh、start_3306.sh、stop_3306.sh到/test/mysql-3306目录，各文件内容以下：

init_3306.sh文件内容：

#!/bin/sh

bin/mysqld --defaults-file=/test/mysql-3306/my.cnf --initialize --user=root --console

login_3306.sh文件内容：

#!/bin/sh

bin/mysql --defaults-file=/test/mysql-3306/my.cnf -uroot -p

start_3306.sh文件内容：

#!/bin/sh


nohup bin/mysqld_safe --defaults-file=/test/mysql-3306/my.cnf --user=root >/dev/null 2>&1 &

stop_3306.sh文件内容：

#!/bin/sh

bin/mysqladmin --defaults-file=/test/mysql-3306/my.cnf shutdown -uroot -pxxxx@2017

六、执行init_3306.sh文件初始化数据库成功；

七、查看log/mysql.log文件中生成的密码；

八、执行start_3306.sh文件启动数据库成功；

九、执行login_3306.sh数据log文件中密码登陆成功；

 

mysql> set sql_log_bin = 0;
Query OK, 0 rows affected (0.00 sec)

mysql> set password=password('xxxx@2017');
Query OK, 0 rows affected, 1 warning (0.00 sec)

mysql> grant all privileges on *.* to 'root'@'%' identified by 'xxxx@2017' with grant option;
Query OK, 0 rows affected, 1 warning (0.01 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

mysql> set sql_log_bin = 1;
Query OK, 0 rows affected (0.00 sec)

mysql> exit
Bye 

 

十、修改my.cnf文件，增长【mysqld】段内配置

server_id = 1
gtid_mode = ON
enforce_gtid_consistency = ON
master_info_repository = TABLE
relay_log_info_repository = TABLE
binlog_checksum = NONE
log_slave_updates = ON
log_bin = binlog
binlog_format = ROW

transaction_write_set_extraction = XXHASH64

十一、重启mysql，执行mysqlsh命令

[root@dbserver01 test]# mysqlsh 
MySQL Shell 1.0.10

Type '\help' or '\?' for help; '\quit' to exit.

Currently in JavaScript mode. Use \sql to switch to SQL mode and execute queries.
mysql-js> dba.configureLocalInstance('root@localhost:3306');
Please provide the password for 'root@localhost:3306': 

Detecting the configuration file...
Default file not found at the standard locations.                  
Please specify the path to the MySQL configuration file: /test/mysql-3306/my.cnf
Validating instance...

The instance 'localhost:3306' is valid for Cluster usage
You can now use it in an InnoDB Cluster.

{
    "status": "ok"
}
mysql-js> 

 十二、建立集群实例

mysql-js> \c root@dbserver01:3306
Creating a Session to 'root@dbserver01:3306'
Enter password: 
Your MySQL connection id is 8
Server version: 5.7.20-log MySQL Community Server (GPL)
No default schema selected; type \use <schema> to set one.
mysql-js> var cluster = dba.createCluster('szcluster');
A new InnoDB cluster will be created on instance 'root@dbserver01:3306'.

Creating InnoDB cluster 'szcluster' on 'root@dbserver01:3306'...
Adding Seed Instance...

Cluster successfully created. Use Cluster.addInstance() to add MySQL instances.
At least 3 instances are needed for the cluster to be able to withstand up to
one server failure.

mysql-js> cluster.status();
{
    "clusterName": "szcluster", 
    "defaultReplicaSet": {
        "name": "default", 
        "primary": "dbserver01:3306", 
        "status": "OK_NO_TOLERANCE", 
        "statusText": "Cluster is NOT tolerant to any failures.", 
        "topology": {
            "dbserver01:3306": {
                "address": "dbserver01:3306", 
                "mode": "R/W", 
                "readReplicas": {}, 
                "role": "HA", 
                "status": "ONLINE"
            }
        }
    }
}
mysql-js> 

 1三、完成另外一台服务器两个实例的配置(执行到十、11步便可，无需执行12步)

 

1四、mysqlrouter --bootstrap root@dbserver01:3306 --user=root
