在企业中服务器重启有时候会遇到mysql 启动报错 Cant change dir to xxx, No such file or directory。大致意思是无法将目录换成xxx因为没有这个目录。
原因通常是配置文件配置的目录有问题或者挂载盘加载慢于mysql启动mysql的data数据放在挂载盘里
linux中配置文件是my.cnf通常路径是 /etc/my.cnf
windows中配置文件是my.ini
mysql配置文件大致内容如下
# mysql路径
basedir/sata09/data/mysql
# mysql存数据的路径
datadir/sata09/data/mysql/data
这篇文章以挂载问题导致为例。
挂载有两种rc.localfstab。
推荐使用fstab。原因如下 开机挂载mount/etc/fstab 与 /etc/rc.d/rc.local 差不多差别就是如果你有程序依赖于NFS的话还是放到fstab比较好。程序启动先加载 /etc/fastab 文件。 放fstab里会在程序启动前加载NFS文件系统放rc.local里往往造成程序启动加载时找不到路径。 我之前的挂载命令是放在 /etc/rc.local现在改成放在 /etc/fstab
