请问在 chroot 下该如何安装 MySQL

补充一下目前的报错信息

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

而我在 /var/run/mysqld/ 目录下面根本找不到 mysqld.sock

安装就直接安装
启动时会报错 Runing in chroot,Ignore request
这时候就手动启动 MySQL，一样的
setsid mysqld_safe > /dev/null 2>&1 &

然后再运行 mysql -uroot ...是不是就可以连上了

@seanan MySQL 服务器没有启动起来
直接 root 用户运行
mysqld_safe
看看提示什么错误
