配置Mysql Cluster时出错Unable to connect with connect string_MySQL

在执行 /etc/init.d/ndbd --initial出现下列错误

[root@ndbd1 ~]# /etc/init.d/ndbd --initial
Unable to connect with connect string: nodeid=0,localhost:1186
Retrying every 5 seconds. Attempts left: 12 11 10 9 8 7 6 5 4 3 2 1, failed.

解决办法

1.查看/etc/my.cnf文件配置

[root@ndbd1 ~]# cat /etc/my.cnf
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0n

[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

2.修改该配置文件

[root@ndbd1 ~]# vim /etc/my.cnf
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
ndbcluster
ndb-connectstring=192.168.0.30

[MYSQL_CLUSTER]
ndb-connectstring=192.168.0.30

[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

3.重新进行初始化

[root@ndbd1 ~]# /etc/init.d/ndbd --initial
2014-05-09 21:45:17 [ndbd] INFO -- Angel connected to '192.168.0.30:1186'
2014-05-09 21:45:17 [ndbd] INFO -- Angel allocated nodeid: 2
