[求助] 惨了，升级mysql5.5，启动不了了

testu

按admin的方法，wget http://down.wdlinux.cn/in/mysql_up55.sh
sh mysql_up55.sh
然后 改写mysqld
basedir=/www/wdlinux/mysql
datadir=/www/wdlinux/mysql/var
然后
。。。。。

楼主好样的。

testu

解决了
一个是mysql目录最好放在home里，很容易占满空间
二是/var/lib/mysql/目录权限不正确，造成sock文件无法创建
还做了几个修改，见招拆招，在服务商客服帮助下搞定了。

testu

[root@west11237 ~]# df -h
文件系统              容量  已用  可用 挂载点
/dev/sda1             9.9G  9.7G     0 100% /
tmpfs                 1.9G     0  1.9G   0% /dev/shm
/dev/sdb1             483G   62G  397G  14% /home

发现空间满了

testu

努力抢修以后
变成这样了
