MySQL5.7.10最新版初始化安装及多实例创建自动部署脚本

21fdfsd

mysql5.7.10_onekey_install.sh自动化部署脚本支持mysql5.7.10初始化安装，多实例创建，且使用经过优化后的my.cnf配置文件和mysql.server启动脚本，该SHELL脚本在CentOS6.5_x86_64操作系统测试通过。
1、安装方式
将mysql5.7.10_onekey_install.zip包上传到Linux服务器解压并执行包中的shell脚本：

解压包：unzip mysql5.7.10_onekey_install.zip

切换目录：cd mysql5.7.10_onekey_install

执行脚本：./mysql5.7.10_onekey_install.sh 3307

# 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

注意：执行脚本后要求带一个参数（端口号），参数要求是整数，且不能与服务器上已有的端口号重复

1、如果是首次安装mysql，则会构建所需的所有预安装环境并创建第一个实例；

2、如果不是首次安装mysql，则会在原有基础上创建多实例；

2、安装软件版本

- 操作系统：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、安装目录规划

上传软件包目录：/home/zkyw/install

mysql程序目录：/opt/application/mysql

mysql实例数据文件目录：/data/$Port

4、程序启停操作

启动mysql实例：/data/$Port/mysql.server start

停止mysql实例: /data/$Port/mysql.server stop

查看mysql实例状态：/data/$Port/mysql.server status

5、脚本执行过程

第一步：对传入的参数（端口号）做判断，要求为整数且不能与服务器已有端口号冲突；

第二步：如果服务器还没有安装过mysql，则进行初始化安装，自动配置所需安装环境；

第三步：如果服务器上已经安装了mysql，则会创建多实例；

第四步：初始化安装过程：删除msyql相关的rpm包→安装libaio包→创建安装所需的用户目录等→安装mysql→配置mysql

第五步：创建多实例过程：创建目录并授权→安装mysql→配置mysql

二、自动化部署脚本
