一、软件包

a) perl-Proc-Daemon-0.03-1.el5.noarch.rpm

b) perl-DBI-1.52-1.fc6.i386.rpm

c) perl-Algorithm-Diff-1.1902-2.el5.noarch.rpm

d) DBD-mysql-4.018.tar.gz

e) mysql-master-master-1.2.6.tar.gz

f) mysql-5.0.27.tar.gz

二、安装步骤

a) Nod1 ip 59.64.30.118 vip 59.64.30.103(read)

b) Node2 ip 59.64.30.107 vip 59.64.30.102(read)

c) Vip 59.64.30.101(writer)

d) Mgr 59.64.28.92(管理节点)

e) 首先安装好MYSQL软件,配置好MYSQL主主同步。(可以正常主主同步数据)

f) Cd /var/local/software

g) rpm -ivh perl-Proc-Daemon-0.03-1.el5.noarch.rpm

h) rpm -ivh perl-DBI-1.52-1.fc6.i386.rpm

i) ln -s /usr/local/mysql/lib/mysql/libmysqlclient.so.15 /bin/libmysqlclient.so.15

j) ln -s /usr/local/mysql/lib/mysql/libmysqlclient.so.15 /usr/bin/libmysqlclient.so.15

k) ln -s /usr/local/mysql/lib/mysql/libmysqlclient.so.15 /usr/lib/libmysqlclient.so.15

l) ln -s /usr/local/mysql/lib/mysql/libmysqlclient.so.15 /usr/sbin/libmysqlclient.so.15

m) ln -s /usr/local/mysql/lib/mysql/libmysqlclient.so.15 /sbin/libmysqlclient.so.15

n) tar zxvf DBD-mysql-4.018.tar.gz

o) cd DBD-mysql-4.018

p) perl Makefile.PL --with-mysql=/usr/local/mysql --mysql_config=/usr/local/mysql/bin/mysql_config

q) make && make test && make install

r) cd ../

s) rpm -ivh perl-Algorithm-Diff-1.1902-2.el5.noarch.rpm

t) tar zxvf mysql-master-master-1.2.6.tar.gz

u) cd mysql-master-master-1.2.6

v) ./install.pl

w) Cd /usr/local/mmm/etc/examples/

x) cp mmm_agent.conf.example mmm_agent.conf

y) >mmm_agent.conf

aa) 同步方法安装mysql_mmm另一台服务器

bb) Vi /usr/local/mmm/etc/mmm_agent.conf

a1) 两个节点服务器MYSQL同时增加如下用户。

GRANT ALL PRIVILEGES on *.* to 'rep_agent'@'%' identified by '123456' WITH GRANT OPTION;

GRANT ALL PRIVILEGES on *.* to 'rep_monitor'@'%' identified by '123456' WITH GRANT OPTION;

MySQL Multi-Master Replication Manager

Version: 1.2.6

Config file: mmm_mon.conf

Daemon is running!

===============================

Cluster failover method: AUTO

===============================

Servers status:

db1(59.64.30.118): master/ONLINE. Roles: reader(59.64.30.103;), writer(59.64.30.101 //这里是虚拟IP;)

db2(59.64.30.107): master/ONLINE. Roles: reader(59.64.30.102 //这里是虚拟IP;)

三、附加

a) 因为主主同步我没在意,都是NO,所以在show过程中状态老报错,最后一直查到修复主主看看,show才正常。警告配置时首先一定要保证MYSQL主主同步是正常的。配置就不会有什么问题。

b) 安装过程中装perl包真麻烦。找了好多包。郁闷死。
