[root@Rnet root]# cd /usr/local/mysql
[root@Rnet mysql]# safe_mysqld mysql &
[1] 16089
[root@Rnet mysql]# Starting mysqld daemon with databases from /usr/local/mysql/data
050714 10:10:20  mysqld ended


[root@Rnet mysql]# ps -ef|grep safe_mysqld
root      6195     1  0 Jul12 ?        00:00:00 vim safe_mysqld
root     16110 14096  0 10:13 pts/1    00:00:00 grep safe_mysqld
[root@Rnet mysql]# pwd
/usr/local/mysql
[root@Rnet mysql]# safe_mysqld --skip-grant-tables &
[1] 16111
[root@Rnet mysql]# Starting mysqld daemon with databases from /usr/local/mysql/data
这次没有mysqld ended，但是同样没有启动，这是为什么

[root@Rnet mysql]# ps -ef|grep safe_mysqld
root      6195     1  0 Jul12 ?        00:00:00 vim safe_mysqld
root     16111 14096  0 10:14 pts/1    00:00:00 /bin/sh /usr/local/mysql/bin/safe_mysqld --skip-grant-tables
root     16131 14096  0 10:15 pts/1    00:00:00 grep safe_mysqld
