脚本命令配置mysql_MySQL 自动化部署脚本
一、環境說明
操作系統：CentOS
數據庫版本：MySQL 5.7/8.0
參數：buffer pool 會根據系統內存指定、默認雙一、GTID、SlowLog
腳本默認安裝路徑：/usr/local/mysql
腳本默認數據路徑：/data/mysql*(根據安裝包版本適應 比如 5.7 mysql57)
二、使用方法
服務器上創建一個 /myinstall 臨時文件夾
mkdir /myinstall
將本地的 MySQL 安裝包 和 mysql_install.py 上傳到服務器：
[root@172-16-104-56 test01]# ll
總用量 645732
-rw-r--r--. 1 root root 661214270 1月 11 13:59 mysql-5.7.32-linux-glibc2.12-x86_64.tar.gz
-rw-r--r--. 1 root root 10727 1月 12 18:34 mysql_install.py
運行 mysql_install.py 即可執行
python mysql_install.py mysql-5.7.32-linux-glibc2.12-x86_64.tar.gz
腳本執行完成后會將登入數據庫的命令打印出來，直接登入即可
接下來修改密碼即可：
ALTER USER 'root'@'localhost' IDENTIFIED BY 'YouPassword';
將 MySQL 添加到 .bash_profile 中：
vi /root/.bash_profile
-- 添加到文件中
PATH=$PATH:$HOME/bin:/usr/local/mysql/bin
-- 保存后 source
source /root/.bash_profile
驗證：
[root@db01 /]# mysql
mysql mysql_embedded
mysqladmin mysqlimport
mysqlbinlog mysql_install_db
mysqlcheck mysql_plugin
mysql_client_test_embedded mysqlpump
mysql_config mysql_secure_installation
mysql_config_editor mysqlshow
mysqld mysqlslap
mysqld-debug mysql_ssl_rsa_setup
mysqld_multi mysqltest_embedded
mysqld_safe mysql_tzinfo_to_sql
mysqldump mysql_upgrade
mysqldumpslow mysqlxtest
[root@db01 /]#
