MySQL单实例安装

1. 环境准备

1、上传MySQL二进制压缩包到Linux上

2、解压到/usr/local/mysql中

 tar -xzvf mysql-5.6.24-linux-glibc2.5-x86_64.tar.gz -C /usr/local/mysql

查看/usr/local/mysql

3、创建新用户

4、/var/local/mysql 更改属主为mysql

5、mysql/bin 添加到环境变量

6、创建mysql数据目录并更改属主为mysql

2. 二进制方式安装MySQL

1、修改my.cnf到/etc/mysql中

2、初始化3306数据库 指定文件/etc/mysql/my3306.cnf

3、查看/data1/db3306 目录

4、查看error.log文件

5、启动mysql3306实例

6、查看端口

3. 测试

1、进入mysql

2、设置root用户的密码为123456

3、使用密码登录mysql

4. 附件 mysql3306.cnf
