zabbix 的报错sock报错

Tail var/log/zabbix/zabbix_server
mysql_connect(): Can'tconnect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)[include/db.inc.php:77]Error connecting to database [Can't connect to localMySQL server through socket '/var/lib/mysql/mysql.sock' (2)]
出现sock问题 sock [2002]

更改配置文件/etc/my.cnf
[mysqld]
port = 3306
socket = /var/lib/mysql/mysql.sock
skip-locking
key_buffer_size = 256M
datadir = /data/mysql
max_allowed_packet = 1M
table_open_cache = 256
sort_buffer_size = 1M
read_buffer_size = 1M
read_rnd_buffer_size = 4M
myisam_sort_buffer_size =64M
thread_cache_size = 8
query_cache_size= 16M
以/etc/zabbix/zabbix_server.conf下的sock路径为正确路径
DBsock =/var/lib/mysql/mysql.sock
