mysql设置定时入伍_mysql 集群自动化配置

發布時間：2025/5/22 数据库 17 豆豆

生活随笔收集整理的這篇文章主要介紹了 mysql设置定时入伍_mysql 集群自动化配置小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

#!/bin/sh

#文件名: autogen_mysql.sh

#功能: 自動生成Mysql集群配置文件,生成環境自動部署,自動運行腳本等

#創建時間: 2012-02-05

#自動化生成的文件列表:

#(執行autogen_mysql.sh后,會生成autogen目錄，里面會存放自動生成的相關文件)

#1. ConfigAllServer.sh ????自動配置所有Mysql集群節點腳本，包括NDB節點，mysql節點，管理節點

#2. RunAllServer.sh????????自動啟動所有Mysql集群節點腳本，包括NDB節點，mysql節點，管理節點

#3. mgm_node.sh ????????啟動，關閉，重啟管理節點腳本.在執行ConfigAllServer.sh時，會將該腳本自動拷貝到管理節點的/etc/目錄下

#4. mysql_node.sh ????????啟動或關閉Mysql節點腳本.在執行ConfigAllServer.sh時，會將該腳本自動拷貝到Mysql節點的/etc/目錄下

#5. ndb_node_start.sh ????啟動NDB節點腳本.在執行ConfigAllServer.sh時，會將該腳本自動拷貝到NDB節點的/etc/目錄下

#6. config.ini ????????????管理配置文件.在執行ConfigAllServer.sh時，會將該配置文件自動拷貝到管理節點的/var/lib/mysql/目錄下

#7. my_ndb.cnf ????????????NDB節點配置文件.在執行ConfigAllServer.sh時，會將該腳本自動拷貝到NDB節點的/etc/目錄下，并命名為my.cnf

#8. my_mysql.cnf???? ????Mysql節點配置腳本.在執行ConfigAllServer.sh時，會將該腳本自動拷貝到Mysql節點的/etc/目錄下，并命名為my.cnf

#注意事項

#1. 執行ConfigAllServer.sh, RunAllServer.sh這兩個腳本的主機需要修改/etc/ssh/ssh_config,將StrictHostKeyChecking設置為no,防止彈出提示框引起自動化無法執行完畢

#　測試　sysbench --mysql-user=uProfile --mysql-password=123456 --test=oltp --mysql-host=10.74.213.38 --oltp-test-mode=complex --mysql-table-engine=ndbcluster --oltp-table-size=5000000 --mysql-db=uProfile --num-threads=64 --max-requests=500000 prepare

# -------------------------------------------------以下根據實際情況進行設定----------------------------------------------------

# ROOT權限密碼,該密碼為所有集群節點通用密碼,所有服務器ROOT將使用統一密碼,便于自動化控制，否則上面提到的ConfigAllServer.sh, RunAllServer.sh這兩個文件無法正常運行

ROOTPASSWORD=123qwe

# 管理節點IP地址

MGM_IP=192.168.254.5

# NDB節點IP數組，數據之間用空格隔開,如'10.0.0.1 10.0.0.2'

NDB_IPS='192.168.254.101 192.168.254.102'

# MySQL節點IP數組，數據之間用空格隔開,如'10.0.0.1 10.0.0.2'

SQL_IPS='192.168.254.10 192.168.254.11'
