mysql_mgr_test

use script to create MySQL Group Replication environments fast and efficiently.

1. download MySQL installation packages. www.mysql.com and ensure IP is configured is /etc/hosts.
   for example, /etc/hosts as below, 10.127.1.18 is current machine IP, and mysqltestdb is hostname,else MGR creation will have issues.
   127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
   ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
   10.127.1.18 mysqltestdb

2. change parameters from file auto.cnf following your environment needs.
   for example, change below parameter values, you need to put mysql running path to /usr/local/mysql and create directory /home/data these can be changed following your needs.

   base_dir=/usr/local/mysql
   base_data_dir=/home/data

3. config file init.lst following your environments needs.
   for example ,I need to crate 5 nodes in one machine, I should config init.lst as below.
   24801 s1 24901 Y
   24802 s2 24902 Y
   24803 s3 24903 Y
   24804 s4 24904 Y
   24805 s5 24905 Y

4. run script init.sh to start MGR environments creation.

   if you need to create single Primary environments, you should put seconds onwards rows, the last values as N,for example.
   24801 s1 24901 Y
   24802 s2 24902 N
   24803 s3 24903 N
   24804 s4 24904 N
   24805 s5 24905 N
   if you need to create multi-Primary environments, you should put node role as Y, for example.
   24801 s1 24901 Y
   24802 s2 24902 Y
   24803 s3 24903 Y
   24804 s4 24904 Y
   24805 s5 24905 Y

5. use check.sh to check node status, you should use input parameter node_name which is included in init.lst for example, we want to check node status ,node name is s2 which is from init.lst
   I should use below command to check
   sh check_node.sh s2
