mysql+proxysql+replication-manager的主从半同步复制+高可用+读写分离

左马盘河

环境：
AlmaLinux release 9.1
MySQL Community Server Ver 8.0.33
Replication Manager v2.2.40 for MariaDB 10.x and MySQL 5.7 Series
ProxySQL version 2.5.1-90-gbedaa6c
主机分配情况：

采用hyper-v创建虚拟机的方式进行的，创建1台模板之后另外3台导入虚拟机复制。
1、安装mysql
mysql8的默认加密插件变为了caching_sha2_password需要修改成mysql_native_password，因为proxysql不支持caching_sha2_password
安装完成后在server01、02、03上创建以下用户
rep-manager供replication-manager使用，repl供主从复制使用

1. mysql> create user 'rep-manager'@'%' identified by 'your password';
2. Query OK, 0 rows affected (0.01 sec)
4. mysql> create user 'repl'@'%' identified by 'your password';
5. Query OK, 0 rows affected (0.02 sec)
7. mysql> create user 'proxysql'@'%' identified by 'your password';
8. Query OK, 0 rows affected (0.02 sec)
10. mysql> grant process,replication slave,replication client on *.* to 'proxysql'@'%';
11. Query OK, 0 rows affected (0.01 sec)
13. mysql> grant select,replication slave,replication client,reload,super on *.* to 'repl'@'%';
14. Query OK, 0 rows affected, 1 warning (0.01 sec)
16. mysql> grant all privileges on *.* to 'rep-manager'@'%' with grant option;
17. Query OK, 0 rows affected (0.01 sec)
19. mysql> flush privileges;
20. Query OK, 0 rows affected (0.01 sec)

复制代码

 
2、复制虚拟机
3、在server00上安装replication-manager
4、在server00上安装proxysql
5、启动mysql，创建主从半同步复制
半同步需要安装插件，在主库和从库上都安装

1. mysql> install plugin rpl_semi_sync_source soname 'semisync_source.so';
2. mysql> install plugin rpl_semi_sync_replica soname 'semisync_replica.so';

10. # IMPORTANT INFORMATION REGARDING THIS CONFIGURATION FILE:                             
11. ########################################################################################
12. # On startup, ProxySQL reads its config file (if present) to determine its datadir.
13. # What happens next depends on if the database file (disk) is present in the defined
14. # datadir (i.e. "/var/lib/proxysql/proxysql.db").
15. #
16. # If the database file is found, ProxySQL initializes its in-memory configuration from
17. # the persisted on-disk database. So, disk configuration gets loaded into memory and
18. # then propagated towards the runtime configuration.
19. #
20. # If the database file is not found and a config file exists, the config file is parsed
21. # and its content is loaded into the in-memory database, to then be both saved on-disk
22. # database and loaded at runtime.
23. #
24. # IMPORTANT: If a database file is found, the config file is NOT parsed. In this case
25. #            ProxySQL initializes its in-memory configuration from the persisted on-disk
26. #            database ONLY. In other words, the configuration found in the proxysql.cnf
27. #            file is only used to initial the on-disk database read on the first startup.
28. #
29. # In order to FORCE a re-initialise of the on-disk database from the configuration file
30. # the ProxySQL service should be started with "systemctl start proxysql-initial".

其实proxysql配置基本上在启动了之后都是通过数据库来设置的配置文件
proxysql的配置如下，进入proxysql

1. [root@server00 ~]# mysql -uadmin -p -P6032 -h127.0.0.1 --prompt='proxysql Admin> '
2. Enter password:

复制代码

 按照以上配置打开replication-manager的web管理端，默认账号admin密码repman

 切换主从后

 

 

切换主从后
 
 在server01的主库上创建appbox用户

1. mysql> create user appbox@'%' identified by 'Appbox@123';
2. Query OK, 0 rows affected (0.01 sec)
4. mysql> create database appboxdb character set utf8mb4;
5. Query OK, 1 row affected (0.01 sec)
7. mysql> grant all privileges on appboxdb.* to appbox@'%';
8. Query OK, 0 rows affected (0.01 sec)
10. mysql>

复制代码

 用Navicat连proxysql

在proxysql中插入读写规则

1. insert into mysql_query_rules(rule_id,active,match_digest,destination_hostgroup,apply)values(1,1,'^SELECT.*FOR UPDATE$',100,1);
2. insert into mysql_query_rules(rule_id,active,match_digest,destination_hostgroup,apply)values(2,1,'^SELECT',1000,1);<br>load mysql query rules to runtime;<br>save mysql query rules to disk;

复制代码

bash下进行读写测试

1. for i in {1..100}; do mysql -uappbox -pAppbox@123 -h server00.mshome.net  -P6033  -e 'select * from mysql.user LIMIT 2;' ; sleep 0.5; done

复制代码
