安装mysql-mmm
1. 安装mysql-mmm-agent
2. agent机器上要安装iproute 包，
3. 如果手工编译的 MYSQL,一定要把加载 MYSQL 的 LIB
# ECHO "/USR/LOCAL/MYSQL/LIB/MYSQL/" >> /ETC/LD.SO.CONF
#LDCONFIG
4. 安装perl库文件（cpan），cpan 分两种安装方式,一种是在线安装, 如下面所示;另一种是手动安装,手动安装需要根据安装模块 search.cpan.org 上 下载下来,然后再安装。
4.1 在 agent机器上都安装如下 perl 库(mysql-agent 需求的 perl 库)
有些 perl 库,特别是红色的三个库系统默认应该是有的,可以通过以下方法查看是否,安装,如果安装,就不必要安装,因为
安装这三个库比较麻烦,特别 DBD::mysql,需要下载软件手工编译
确认是否安装一下模块:
#find /usr/lib/perl5/ -name mysql.pm (rhel默认没有，需要手动安装DBD-mysql)
#find /usr/lib/perl5/ -name stat.pm
#find /usr/lib/perl5/ -name Basename.pm
红色的应该是系统自带的:
DBI and DBD::mysql （如果没有，这个要先装）
在 PERL MAKEFILE.PL 的时候,一定要指定你定制的一些 MYSQL 的信息
#PERL MAKEFILE.PL --MYSQL_CONFIG=/USR/LOCAL/MYSQL/BIN/MYSQL_CONFIG --WITH- MYSQL=/USR/LOCAL/MYSQL/
一定要 MAKE TEST,通过了再 MAKE INSTALL
File::Basename
File::stat
File::Temp
Net::Ping （放在最后安装）
Algorithm::Diff
Class::Singleton
Log::Log4perl
Log::Dispatch (需要安装ExtUtils-MakeMaker,Params-Validate,Sys-Syslog)
Mail:Send (需要安装 TimeDate，Pod::Escapes，Pod-Simple，ExtUtils-CBuilder，ExtUtils- Par***S，Test-Harness，Compress-Raw-Zlib，Compress-Raw-Bzip2，IO- Compress，Package-Constants，IO-Zlib，Text-Diff，Archive-Tar，podlators，Pod- Readme，ExtUtils-Install，Module::Metadata，Test-Simple，Perl-OSType，Module- Build，Test::Pod，MailTools)
Proc::Daemon
Thread::Queue(在 rhel5.6 版本中,需要先装 threads,再装 threads-shared,再装 threads-queue;依据提示 安装版本,否则后面到 mysql-mmm-monitor 无法启动)

5. 安装mysql-mmm
5.1 tar xf mysql-mmm.<version>.tar.gz
5.2 make install
6. 启动mysql-mmm-agent（是否能正常运行，能运行后，再关闭）
/etc/init.d/mysql-mmm-agent start
安装脚本：
#! /bin/bash
pathname="/usr/lib/perl5/site_perl/5.8.8/i386-linux-thread-multi/DBD"
cpanpath=/root/cpan
echo "/usr/local/mysql/lib/mysql/" >> /etc/ld.so.conf
ldconfig
file1="DBD-mysql-4.020.tar.gz"
file2="perl-DBI-1.52-2.el5.i386.rpm"
ls $cpanpath > /root/file
while read i
do
file3=$(rpm -qa perl-DBI |awk -F "1" '{print $1}')
if [ "$file3" != "perl-DBI-" ]
then
rpm -ivh $cpanpath/$i
sleep 2
else
if [ -d $pathname ]
then
tar xf $cpanpath/$i -C /tmp && cd /tmp/$(echo $i |awk -F ".tar" '{print $1}')
perl Makefile.PL && make test && make install
mv $cpanpath/$i /root
else
if [ "$i" = "$file1" ]
then
tar xf $cpanpath/$i -C /tmp && cd /tmp/$(echo $i |awk -F ".tar" '{print $1}')
perl Makefile.PL --mysql_config=/usr/local/mysql/bin/mysql_config --with-mysql=/usr/local/mysql && make test && make install && mv $cpanpath/$i /root
continue
fi
fi
fi
done < /root/file
for j in `ls /root/cpan`
do
tar xf $cpanpath/$j -C /tmp && cd /tmp/$(echo $j |awk -F ".tar" '{print $1}')
perl Makefile.PL && make test && make install
mv $cpanpath/$j /root
done
tar xf /root/mysql-mmm* -C /tmp && cd /tmp/mysql-mmm* && make install
rm -rf /root/file
配 置 MYSQL-MMM-AGENTD
添加 agentd 使用的 mysql 用户,db1,db2,db3 都要添加
db1,db2,db3:
mysql>grant super,replication client,process on *.* to 'mmm_agent'@'192.168.56.101' identified by 'mmm_agent';
mysql>grant super,replication client,process on *.* to 'mmm_agent'@'192.168.56.103' identified by 'mmm_agent';
mysql>grant super,replication client,process on *.* to 'mmm_agent'@'192.168.56.105' identified by 'mmm_agent';
mysql>grant super,replication client,process on *.* to 'mmm_agent'@'192.168.56.99' identified by 'mmm_agent';
修改mysql-mmm配置文件
db1：
# cat /etc/mysql-mmm/mmm_agent.conf
include mmm_common.conf
this db1
# cat /etc/mysql-mmm/mmm_common.conf
active_master_role writer
<host default>
cluster_interface eth0
pid_path /var/run/mmm_agentd.pid
bin_path /usr/lib/mysql-mmm/
replication_user slave
replication_password 123456
agent_user mmm_agent
agent_password 123456
</host>
<host db1>
ip 192.168.56.101
mode master
peer db2
</host>
<host db2>
ip 192.168.56.103
mode master
peer db1
</host>
<host db3>
ip 192.168.56.105
mode slave
</host>
<role writer>
hosts db1, db2
ips 192.168.56.200
mode exclusive
</role>
<role reader>
hosts db1, db2,db3
ips 192.168.56.201,192.168.56.203,192.168.56.205
mode balanced
</role>
将db1的/etc/mysql-mmm/mmm_common.conf文件拷贝到db2，db3，db4相同的位置，拷贝方法自定义
db2:
# cat /etc/mysql-mmm/mmm_agent.conf
include mmm_common.conf
this db2
db3:
# cat /etc/mysql-mmm/mmm_agent.conf
include mmm_common.conf
this db3
启动MYSQL-mmm_agent
db1，db2，db3：
# /etc/init.d/mysql-mmm-agent start
Daemon bin: '/usr/sbin/mmm_agentd'
Daemon pid: '/var/run/mmm_agentd.pid'
Starting MMM Agent daemon... Ok
# /etc/init.d/mysql-mmm-agent status
Daemon bin: '/usr/sbin/mmm_agentd'
Daemon pid: '/var/run/mmm_agentd.pid'
Checking MMM Agent process: running.
[root@(155/15)~]# ps aux | grep mmm
root 26758 0.0 0.1 11524 6912 ? S 14:52 0:00 mmm_agentd
root 26759 0.0 0.1 11568 7088 ? S 14:52 0:00 mmm_agentd
root 26798 0.0 0.0 3920 672 pts/1 S+ 14:55 0:00 grep mmm
[root@(155/15)~]# netstat -tulnp | grep mmm
tcp 0 0 192.168.56.101:9989 0.0.0.0:* LISTEN 26759/mmm_agentd
[root@(155/15)~]# /etc/init.d/mysql-mmm-agent --help
Daemon bin: '/usr/sbin/mmm_agentd'
Daemon pid: '/var/run/mmm_agentd.pid'
Usage: /etc/init.d/mysql-mmm-agent {start|stop|restart|status}
Note:如果不能启动，可以查看/var/log/mysql-mmm/mmm_agentd.log 文件的提示，或者启动时候的报错，最大的可能是perl对应模块没有安装成功，成功安装对应的模块就可以解决问题了。
配置MYSQL-MMM-monitor
创建mmm-monitor使用的mysql用户，在db1，db2，db3上
db1，db2，db3：
mysql>grant replication client on *.* to 'mmm_monitor'@'192.168.56.99' identified by '123456';
在实际使用中可以简化用户，让复制，agent，monitor使用同一个用户，注意权限就可以行了。下面配置monitor
db4:
# cat /etc/mysql-mmm/mmm_mon.conf
include mmm_common.conf
<monitor>
ip 10.1.1.12
pid_path /var/run/mmm_mond.pid
bin_path /usr/lib/mysql-mmm/
status_path /var/lib/misc/mmm_mond.status
ping_ips 192.168.56.105, 192.168.56.103, 192.168.56.101
</monitor>
<host default>
monitor_user mmm_monitor
monitor_password mmm_monitor
</host>
debug 0
启动MYSQL-MMM-monitor
# /etc/init.d/mysql-mmm-monitor start
Daemon bin: '/usr/sbin/mmm_mond'
Daemon pid: '/var/run/mmm_mond.pid'
Starting MMM Monitor daemon: Ok
[root@(140/12)~]# /etc/init.d/mysql-mmm-monitor --help
Daemon bin: '/usr/sbin/mmm_mond'
Daemon pid: '/var/run/mmm_mond.pid'
Usage: /etc/init.d/mysql-mmm-monitor {start|stop|restart|status}
# ps aux | grep mmm

root 2754 0.5 0.1 12860 7820 ? S 15:10 0:00 perl /usr/lib/mysql-mmm//monitor/checker rep_threads
管理MYSQL-MMM-monitor
查看mmm集群节点的状态：
db4:
# mmm_control mode
ACTIVE
# mmm_control show
db1(192.168.56.101) master/AWAITING_RECOVERY. Roles:
db2(192.168.56.103) master/AWAITING_RECOVERY. Roles:
db3(192.168.56.105) slave/AWAITING_RECOVERY. Roles:
现在都处于AWATING_RECOVERY状态
我们将db1和db2两个master置于ONLINE状态
# mmm_control set_online db1
OK: State of 'db1' changed to ONLINE. Now you can wait some time and check its new roles!
# mmm_control set_online db2
OK: State of 'db2' changed to ONLINE. Now you can wait some time and check its new roles!
# mmm_control show
db1(192.168.56.101) master/ONLINE. Roles: reader(192.168.56.203), writer(192.168.56.200)
db2(192.168.56.103) master/ONLINE. Roles: reader(192.168.56.201), reader(192.168.56.205)
db3(192.168.56.105) slave/AWAITING_RECOVERY. Roles:。
现在mysql-mmm两个master的模式已经搭建完成，我们对所有节点做一次检查：
# mmm_control checks all
db2 ping [last change: 2011/05/18 15:10:15] OK
db2 mysql [last change: 2011/05/18 15:10:15] OK
db2 rep_threads [last change: 2011/05/18 15:10:15] OK
db2 rep_backlog [last change: 2011/05/18 15:10:15] OK: Backlog is null
db3 ping [last change: 2011/05/18 15:10:15] OK
db3 mysql [last change: 2011/05/18 15:10:15] OK
db3 rep_threads [last change: 2011/05/18 15:10:15] ERROR: Replication is not set up
db3 rep_backlog [last change: 2011/05/18 15:10:15] ERROR: Replication is not set up
db1 ping [last change: 2011/05/18 15:10:15] OK
db1 mysql [last change: 2011/05/18 15:10:15] OK
db1 rep_threads [last change: 2011/05/18 15:10:15] OK
db1 rep_backlog [last change: 2011/05/18 15:10:15] OK: Backlog is null
db1和db2已经正常了，只有db3复制是失败的，因为我们还没有配置，只要将db3作为slave加入其中，就完成两个master多个slave的架构。

配 置 MYSQL-MMM-AGENTD
添加 agentd 使用的 mysql 用户,db1,db2,db3 都要添加
db1,db2,db3:
mysql>grant super,replication client,process on *.* to 'mmm_agent'@'192.168.56.101' identified by 'mmm_agent';
mysql>grant super,replication client,process on *.* to 'mmm_agent'@'192.168.56.103' identified by 'mmm_agent';
mysql>grant super,replication client,process on *.* to 'mmm_agent'@'192.168.56.105' identified by 'mmm_agent';
mysql>grant super,replication client,process on *.* to 'mmm_agent'@'192.168.56.99' identified by 'mmm_agent';
修改mysql-mmm配置文件
db1：
# cat /etc/mysql-mmm/mmm_agent.conf
include mmm_common.conf
this db1
# cat /etc/mysql-mmm/mmm_common.conf
active_master_role writer
<host default>
cluster_interface eth0
pid_path /var/run/mmm_agentd.pid
bin_path /usr/lib/mysql-mmm/
replication_user slave
replication_password 123456
agent_user mmm_agent
agent_password 123456
</host>
<host db1>
ip 192.168.56.101
mode master
peer db2
</host>
<host db2>
ip 192.168.56.103
mode master
peer db1
</host>
<host db3>
ip 192.168.56.105
mode slave
</host>
<role writer>
hosts db1, db2
ips 192.168.56.200
mode exclusive
</role>
<role reader>
hosts db1, db2,db3
ips 192.168.56.201,192.168.56.203,192.168.56.205
mode balanced
</role>
将db1的/etc/mysql-mmm/mmm_common.conf文件拷贝到db2，db3，db4相同的位置，拷贝方法自定义
db2:
# cat /etc/mysql-mmm/mmm_agent.conf
include mmm_common.conf
this db2
db3:
# cat /etc/mysql-mmm/mmm_agent.conf
include mmm_common.conf
this db3
启动MYSQL-mmm_agent
db1，db2，db3：
# /etc/init.d/mysql-mmm-agent start
Daemon bin: '/usr/sbin/mmm_agentd'
Daemon pid: '/var/run/mmm_agentd.pid'
Starting MMM Agent daemon... Ok
# /etc/init.d/mysql-mmm-agent status
Daemon bin: '/usr/sbin/mmm_agentd'
Daemon pid: '/var/run/mmm_agentd.pid'
Checking MMM Agent process: running.
[root@(155/15)~]# ps aux | grep mmm
root 26758 0.0 0.1 11524 6912 ? S 14:52 0:00 mmm_agentd
root 26759 0.0 0.1 11568 7088 ? S 14:52 0:00 mmm_agentd
root 26798 0.0 0.0 3920 672 pts/1 S+ 14:55 0:00 grep mmm
[root@(155/15)~]# netstat -tulnp | grep mmm
tcp 0 0 192.168.56.101:9989 0.0.0.0:* LISTEN 26759/mmm_agentd
[root@(155/15)~]# /etc/init.d/mysql-mmm-agent --help
Daemon bin: '/usr/sbin/mmm_agentd'
Daemon pid: '/var/run/mmm_agentd.pid'
Usage: /etc/init.d/mysql-mmm-agent {start|stop|restart|status}
Note:如果不能启动，可以查看/var/log/mysql-mmm/mmm_agentd.log 文件的提示，或者启动时候的报错，最大的可能是perl对应模块没有安装成功，成功安装对应的模块就可以解决问题了。
配置MYSQL-MMM-monitor
创建mmm-monitor使用的mysql用户，在db1，db2，db3上
db1，db2，db3：
mysql>grant replication client on *.* to 'mmm_monitor'@'192.168.56.99' identified by '123456';
在实际使用中可以简化用户，让复制，agent，monitor使用同一个用户，注意权限就可以行了。下面配置monitor
db4:
# cat /etc/mysql-mmm/mmm_mon.conf
include mmm_common.conf
<monitor>
ip 10.1.1.12
pid_path /var/run/mmm_mond.pid
bin_path /usr/lib/mysql-mmm/
status_path /var/lib/misc/mmm_mond.status
ping_ips 192.168.56.105, 192.168.56.103, 192.168.56.101
</monitor>
<host default>
monitor_user mmm_monitor
monitor_password mmm_monitor
</host>
debug 0
启动MYSQL-MMM-monitor
# /etc/init.d/mysql-mmm-monitor start
Daemon bin: '/usr/sbin/mmm_mond'
Daemon pid: '/var/run/mmm_mond.pid'
Starting MMM Monitor daemon: Ok
[root@(140/12)~]# /etc/init.d/mysql-mmm-monitor --help
Daemon bin: '/usr/sbin/mmm_mond'
Daemon pid: '/var/run/mmm_mond.pid'
Usage: /etc/init.d/mysql-mmm-monitor {start|stop|restart|status}
# ps aux | grep mmm
root 2737 0.0 0.2 13764 8892 ? S 15:10 0:00 mmm_mond
root 2738 1.3 0.9 108480 39992 ? Sl 15:10 0:00 mmm_mond
root 2745 0.4 0.1 10676 6668 ? S 15:10 0:00 perl /usr/lib/mysql-mmm//monitor/checker ping_ip
root 2748 0.5 0.1 12860 7776 ? S 15:10 0:00 perl /usr/lib/mysql-mmm//monitor/checker mysql
root 2750 0.4 0.1 10676 6668 ? S 15:10 0:00 perl /usr/lib/mysql-mmm//monitor/checker ping
root 2752 0.5 0.1 12860 7824 ? S 15:10 0:00 perl /usr/lib/mysql-mmm//monitor/checker rep_backlog
root 2754 0.5 0.1 12860 7820 ? S 15:10 0:00 perl /usr/lib/mysql-mmm//monitor/checker rep_threads
管理MYSQL-MMM-monitor
查看mmm集群节点的状态：
db4:
# mmm_control mode
ACTIVE
# mmm_control show
db1(192.168.56.101) master/AWAITING_RECOVERY. Roles:
db2(192.168.56.103) master/AWAITING_RECOVERY. Roles:
db3(192.168.56.105) slave/AWAITING_RECOVERY. Roles:
现在都处于AWATING_RECOVERY状态
我们将db1和db2两个master置于ONLINE状态
# mmm_control set_online db1
OK: State of 'db1' changed to ONLINE. Now you can wait some time and check its new roles!
# mmm_control set_online db2
OK: State of 'db2' changed to ONLINE. Now you can wait some time and check its new roles!
# mmm_control show
db1(192.168.56.101) master/ONLINE. Roles: reader(192.168.56.203), writer(192.168.56.200)
db2(192.168.56.103) master/ONLINE. Roles: reader(192.168.56.201), reader(192.168.56.205)
db3(192.168.56.105) slave/AWAITING_RECOVERY. Roles:。
现在mysql-mmm两个master的模式已经搭建完成，我们对所有节点做一次检查：
# mmm_control checks all
db2 ping [last change: 2011/05/18 15:10:15] OK
db2 mysql [last change: 2011/05/18 15:10:15] OK
db2 rep_threads [last change: 2011/05/18 15:10:15] OK
db2 rep_backlog [last change: 2011/05/18 15:10:15] OK: Backlog is null
db3 ping [last change: 2011/05/18 15:10:15] OK
db3 mysql [last change: 2011/05/18 15:10:15] OK
db3 rep_threads [last change: 2011/05/18 15:10:15] ERROR: Replication is not set up
db3 rep_backlog [last change: 2011/05/18 15:10:15] ERROR: Replication is not set up
db1 ping [last change: 2011/05/18 15:10:15] OK
db1 mysql [last change: 2011/05/18 15:10:15] OK
db1 rep_threads [last change: 2011/05/18 15:10:15] OK
db1 rep_backlog [last change: 2011/05/18 15:10:15] OK: Backlog is null
db1和db2已经正常了，只有db3复制是失败的，因为我们还没有配置，只要将db3作为slave加入其中，就完成两个master多个slave的架构。
