1、限于环境,只有2台服务器,一台安装mysql + mysqlrouter,另一台安装2个mysql实例;
2、添加2台服务器的/etc/hosts文件,如下:
192.168.1.223 dbserver01192.168.1.224 dbserver02
3、准备安装包文件:
mysql-router-2.1.4-linux-glibc2.12-x86-64bit.tar.gzmysql-shell-1.0.10-linux-glibc2.12-x86-64bit.tar.gzmysql-5.7.20-linux-glibc2.12-x86_64.tar.gz
4、解压安装包到相应目录如:/test/mysql-3306,在/test/mysql-3306目录下创建data、log目录,创建my.cnf文件
my.cnf文件内容:
[mysqld]port = 3306socket=/test/mysql-3306/mysql.sockbasedir=/test/mysql-3306datadir=/test/mysql-3306/datalog-error=/test/mysql-3306/log/mysql.logpid-file=/test/mysql-3306/mysql.pid# Disabling symbolic-links is recommended to prevent assorted security riskssymbolic-links=0[mysqld_safe]port = 3306socket=/test/mysql-3306/mysql.sockbasedir=/test/mysql-3306datadir=/test/mysql-3306/datalog-error=/test/mysql-3306/log/mysql.logpid-file=/test/mysql-3306/mysql.pid[mysql]port = 3306socket=/test/mysql-3306/mysql.sock[mysqladmin]port = 3306socket=/test/mysql-3306/mysql.sock
5、拷贝init_3306.sh、login_3306.sh、start_3306.sh、stop_3306.sh到/test/mysql-3306目录,各文件内容如下:
init_3306.sh文件内容:
#!/bin/shbin/mysqld --defaults-file=/test/mysql-3306/my.cnf --initialize --user=root --console
login_3306.sh文件内容:
#!/bin/shbin/mysql --defaults-file=/test/mysql-3306/my.cnf -uroot -p
start_3306.sh文件内容:
#!/bin/shnohup bin/mysqld_safe --defaults-file=/test/mysql-3306/my.cnf --user=root >/dev/null 2>&1 &
stop_3306.sh文件内容:
#!/bin/shbin/mysqladmin --defaults-file=/test/mysql-3306/my.cnf shutdown -uroot -pxxxx@2017
6、执行init_3306.sh文件初始化数据库成功;
7、查看log/mysql.log文件中生成的密码;
8、执行start_3306.sh文件启动数据库成功;
9、执行login_3306.sh数据log文件中密码登录成功;
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> exitBye
10、修改my.cnf文件,增加【mysqld】段内配置
server_id = 1gtid_mode = ONenforce_gtid_consistency = ONmaster_info_repository = TABLErelay_log_info_repository = TABLEbinlog_checksum = NONElog_slave_updates = ONlog_bin = binlogbinlog_format = ROWtransaction_write_set_extraction = XXHASH64
11、重启mysql,执行mysqlsh命令

12、创建集群实例
mysql-js> \c root@dbserver01:3306Creating a Session to 'root@dbserver01:3306'Enter password: Your MySQL connection id is 8Server version: 5.7.20-log MySQL Community Server (GPL)No default schema selected; type \useto 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 toone 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>
13、完成另一台服务器两个实例的配置(执行到10、11步即可,无需执行12步)
14、mysqlrouter --bootstrap root@dbserver01:3306 --user=root
