linux 安装mysql5.6版本 步骤

1.卸载老版本MySQL
find / -name mysql
rm -rf 上边查找到的路径，多个路径用空格隔开 #或者下边一条命令即可 find / -name mysql|xargs rm -rf

2.解压文件
tar -zxvf mysql-5.6.31-linux-glibc2.5-x86_64.tar.gz

3.删除安装包，重命名解压后的文件
rm -f mysql-5.6.31-linux-glibc2.5-x86_64.tar.gz mv mysql-5.6.31-linux-glibc2.5-x86_64/ mysql

useradd -r -g mysql mysql
检车mysql组是否存在 groups mysql

mkdir ./data/mysql
chown -R mysql:mysql ./
./scripts/mysql_install_db --user=mysql --datadir=/usr/local/mysql/data/mysql
cp support-files/mysql.server /etc/init.d/mysqld
chmod 755 /etc/init.d/mysqld
cp support-files/my-default.cnf /etc/my.cnf
 ```
 ```
#修改启动脚本
vi /etc/init.d/mysqld
 ```
 ```
#修改项：
basedir=/usr/local/mysql/
datadir=/usr/local/mysql/data/mysql
 ```
 ```
#启动服务
service mysqld start
 ```
 ```
