创建数据目录

创建数据目录以存储MySQL的数据文件。

1. 创建数据目录“/data”和进程所需的相关目录。

   1 2 3

   mkdir -p /data/mysql cd /data/mysql mkdir data tmp run log relaylog

2. 修改数据目录“/data”的用户组和用户权限为mysql:mysql。

   1 2	chown -R mysql:mysql /data ll /

   预期结果示例：可以看到“/data”的用户组和用户权限已经修改为mysql:mysql。

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23
