MySQL5.7多例項自動化部署指令碼
阿新 • • 發佈：2018-12-30
一、安裝說明
------------------------------------------------------
mysql5.7.10_onekey_install.sh自動化部署指令碼支援mysql5.7.10初始化安裝，多例項建立，且使用經過優化後的my.cnf配置檔案和mysql.server啟動指令碼，該SHELL指令碼在CentOS6.5_x86_64作業系統測試通過。部署示意圖如下：
1、安裝方式
需要準備的檔案如下，放到同一個目錄下，然後執行shell指令碼
執行方式：
| 1 2 |
.
/mysql5
.7.10_onekey_install.sh 3307
埠自定義，要求整數，且不和伺服器埠衝突

| 1 2 3 4 5 6 |
# tree mysql5.7.10_onekey_install
mysql5.7.10_onekey_install
├── my.cnf
├── mysql-5.7.10-linux-glibc2.5-x86_64.
tar
.gz
├── mysql5.7.10_onekey_install.sh└── mysql.server
|
1、如果是首次安裝mysql，則會構建所需的所有預安裝環境並建立第一個例項；
2、如果不是首次安裝mysql，則會在原有基礎上建立多例項；
2、安裝軟體版本
- 作業系統：CentOS6.5_x86_64
- MySQL版本：mysql-5.7.10-linux-glibc2.5-x86_64.tar.gz （最新版本5.7.10）
3、安裝目錄規劃
上傳軟體包目錄：/home/zkyw/install
mysql程式目錄：/opt/application/mysql
mysql例項資料檔案目錄：/data/$Port
4、程式啟停操作
啟動mysql例項：/data/$Port/mysql.server start
停止mysql例項: /data/$Port/mysql.server stop
檢視mysql例項狀態：/data/$Port/mysql.server status
5、指令碼執行過程
第一步：對傳入的引數（埠號）做判斷，要求為整數且不能與伺服器已有埠號衝突；
第二步：如果伺服器還沒有安裝過mysql，則進行初始化安裝，自動配置所需安裝環境；
第三步：如果伺服器上已經安裝了mysql，則會建立多例項；
第四步：初始化安裝過程：刪除msyql相關的rpm包→安裝libaio包→建立安裝所需的使用者目錄等→安裝mysql→配置mysql
第五步：建立多例項過程：建立目錄並授權→安裝mysql→配置mysql
