一、安装说明
------------------------------------------------------
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。部署示意图如下：
1、安装方式
需要准备的文件如下，放到同一个目录下，然后执行shell脚本
执行方式：
|
1
2
|
./mysql5.7.10_onekey_install.sh 3307
端口自定义，要求整数，且不和服务器端口冲突

# 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
