有人在solaris上测试cluster成功过吗？

lovechina

我的SQL 节点无法加入cluster中！！！有人遇到这个问题吗？

我参考这个white paper [
Installation of MySQLTM 5.1 Cluster Software on the SolarisTM 10 OS for x64 Platforms
] 安装 mysql cluster于 solaris10.

Management node, DATA node, SQL node 都可以启动成功，但是下面的命令显示, SQL nodes没有加入cluser中。
"ndb_mgm> show


下面是我在mysql论坛的提问，结果没有任何人回答。请朋友们帮助我！！！万分感激！！！折磨我好多天了！！！

I have tried to run Management node, DATA node and SQL node on the same server, please refer to Part I.
I tried run DATA node on one server, and MANAGEMENT node, SQL node on the other server, please refer to Part II.
But none of this two cases works!
------------------------------------------------------------------------
------------------------------------------------------------------------
------------------------------------------------------------------------
Part I: Single server

Management node, data node and SQL node all run on the same server.
They share the same my.cnf
-------------------------------------

My environment:
1)server: sunws05, Solaris 10 SPARC
2)software: mysql-cluster-gpl-7.0.9-solaris10-sparc-64bit.pkg [unzipped]

------------------------------------------------------------------------
steps:
1. Log in the server and switch to root context:
login as: yxiang
...
sunws05:/home/yxiang$
sunws05:/home/yxiang$ su
Password:***
# su - root
Sun Microsystems Inc.   SunOS 5.10      Generic January 2005
sunws05:/#
sunws05:/# bash

-------------------------------------

2. clean all mysql related things:

2.1 After all mysql-related processes are killed:
sunws05:/# ps -ef |grep mysql
    root 23297 22979   0 09:08:39 pts/3       0:00 grep mysql
sunws05:/#

2.2 uninstall mysql
sunws05:/# pkginfo | grep mysql
application mysql                            MySQL Cluster Server (GPL)
sunws05:/# pkgrm mysql
    .........................
    Removal of <mysql> was successful.

2.3 clean all data and dirs:
sunws05:/# cd /opt/mysql/mysql
sunws05:/opt/mysql/mysql# ls
data           mysql-cluster
sunws05:/opt/mysql/mysql# rm -r data
sunws05:/opt/mysql/mysql# rm -r mysql-cluster
sunws05:/opt/mysql/mysql#

sunws05:/# cd /var/lib
sunws05:/var/lib# ls
gdm            log            mysql          mysql-cluster  pgsql          sgml
sunws05:/var/lib# rm -r mysql
sunws05:/var/lib#

sunws05:/var/lib# cd /etc/mysql
sunws05:/etc/mysql# ls
config.ini  my.cnf      temp
sunws05:/etc/mysql#
sunws05:/etc/mysql# rm config.ini
sunws05:/etc/mysql# rm my.cnf


-------------------------------------


3. Installation:
3.1 add mysql user and group
sunws05:/var/lib# groupadd mysql
UX: groupadd: ERROR: mysql is already in use.  Choose another.
sunws05:/var/lib# useradd -g mysql mysql

上面安装一切看起来正常，可是SQL节点就是无法加入到cluster中，我研究了2个多星期了，一直没有结果。

下面的内容是我另外的一种做法，请朋友们帮帮我分析下，万分感谢！那么多论坛，就这个中文的好像还活跃一点。

You can see that SQL NODE is started, but does NOT join the cluster.
I tried similar configuraiotn on two redhat EL 5.3 servers, everything is OK, even when server-id is NOT set!!!

~~~~~~~~we can see that mysqld is stared!!! but it does NOT work, i'll show you later.

6.3.2 show cluster info:
sunws05:/# ndb_mgm
-- NDB Cluster -- Management Client --
ndb_mgm> show

[ndb_mgmd(MGM)] 1 node(s)

[mysqld(API)] 2 node(s)
id=4 (not connected, accepting connect from 10.80.1.15)
id=5 (not connected, accepting connect from any host)

ndb_mgm>

~~~~~~we can see, SQL node does NOT join the mysql cluster!!!


6.3.3 Now, let's see the error file[/var/lib/mysql/sunws05.err] again, i find that below contents are added:
100212 14:00:12 [Warning] NDB: Could not acquire global schema lock (4009)Cluster Failure
100212 14:03:15 [Warning] NDB: Could not acquire global schema lock (4009)Cluster Failure
100212 14:03:53 [Warning] NDB: Could not acquire global schema lock (4009)Cluster Failure

6.3.4 create DB:
mysql> CREATE TABLE Persons(
-> Id_P int,
-> LastName varchar(255),
-> FirstName varchar(255),
-> Address varchar(255),
-> City varchar(255)
-> )ENGINE=NDBCLUSTER;
ERROR 1005 (HY000): Can't create table 'genview.Persons' (errno: 157)



You can see that SQL NODE is started, but does NOT join the cluster.
I tried similar configuraiotn on two redhat EL 5.3 servers, everything is OK, even when server-id is NOT set!!!

没有细看，有的只是提示：
1、所以的安装都用rpm包方式的，最好是用官方发布的最新的，适合你OS环境的。
2、你的问题与配置有关，仔细检查你的配置文件。如：server-id等。
3、OS方面的配置文件也要检查，如hosts
另外建议你看看"深入浅出MySQL数据库开发、优化与管理维护.pdf"一书中关于cluster一章节，简单易学。我放在了文档资料栏目中了，你找找吧...
