错误原因：

不能写入默认的pid文件，就 修改 /etc/init.d/mysqld，把pid指向别的路经

[root@app60 mysqld]# vi /etc/init.d/mysqld

.....

get_mysql_option mysqld datadir "/var/lib/mysql"
datadir="$result"
get_mysql_option mysqld socket "$datadir/mysql.sock"
socketfile="$result"
get_mysql_option mysqld_safe log-error "/var/log/mysqld.log"
errlogfile="$result"
get_mysql_option mysqld_safe pid-file "/opt/mysqldata/mysqld.pid"    # '/var/run/mysqld/mysqld.pid' 原始值,这里修改成别的路径/opt/mysqldata/mysqld.pid
mypidfile="$result"

.....

然后启动mysqld服务，OK，成功了。
