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 |
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
