csmail双机配置

邮件启动
/etc/init.d/mysql.server.front.csmail start
/etc/init.d/mysql.server.csmail start
/etc/init.d/csmail.rc start
邮件件关闭
/etc/init.d/csmail.rc stop
/etc/init.d/mysql.server.csmail stop
/etc/init.d/mysql.server.front.csmail stop

1.准备双机环境
    操作系统:    CentOS release 5.8 (Final)
    三台机器:    csmail_ha1    --ha1    --192.168.0.21    ->第一台csmail
            csmail_ha2    --ha2    --192.168.0.22    ->第二台csmail
            csmail_nfs    --nfs    --192.168.0.30    ->两台机器的共用存储，使用nfs
                    --vip    --192.168.0.20    ->虚拟IP
2.相关软件
    csmail邮件8.12版本
    heartbeat-2.1.4.tar.bz2
3.系统配置
    .
    .nfs配置
        在csmail_nfs主机建/csdata目录，并共享出去
        /csdata 192.168.0.0/24(rw,sync,no_root_squash)
   
    .以下操作要在ha1和ha2都做一次
    .安装依赖组件:
        yum groupinstall -y "Legacy Software Development" "Legacy Software Support" \
                    "Development Libraries" "Development Tools"
   
    .更新ha1和ha2对应的主机名

    .创建用户和用户组，要保证两台机器的uid和gid相同,组id为600，uid为601
        groupadd -g 600 haclient
        useradd -u 601 -g haclient hacluster
    .设置/etc/hosts文件
        csmail_ha1    192.168.0.21
        csmail_ha2    192.168.0.22
        同时指出自己是哪台机器
        127.0.0.1    csmail_ha? localhost.localdomain localhost
        ::1        csmail_ha? localhost6.localdomain6 localhost6
    .设置/etc/sysconfig/networks
        NETWORKING=yes
        NETWORKING_IPV6=yes
        #HOSTNAME=localhost.localdomain
        HOSTNAME=csmail_ha?
    .设置/etc/reslov.conf
        第一行：search localdomain  先查找本地hosts文件
       
       
4.安装过程
    a.安装邮件
        .在ha1安装邮件，执行setup.sh安装
        .ha1查看/etc/passwd，找到以下三个对应的行，并复制到ha2的passwd文件中
            csmail:x:500:501::/opt/foundir/csmail:/bin/bash
            postfix:x:501:503::/home/postfix:/bin/bash
            mysql:x:502:504::/home/mysql:/bin/bash
        .ha1查看/etc/group，找到以下个对应的行，并复制到ha2的group文件中
            postdrop:x:500:
            foundir:x:501:
            csmail:x:502:csmail
            postfix:x:503:
            mysql:x:504:
        .在ha2安装邮件，执行setup.sh安装
        .关闭开机自动启动,后面程序的启动会由heartbeat来控制
            chkconfig mysql.server.front.csmail off
            chkconfig mysql.server.csmail off
            chkconfig csmail.rc off
    b.安装heartbeat
        .上传软件包Heartbeat-2-1-STABLE-2.1.4.tar.bz2并解压
        .cd到解压出来的目录
        ./bootstrap --prefix=/opt/heartbeat && make && make install
        .cp /opt/heartbeat/share/doc/heartbeat-2.1.4/{ha.cf,haresources,authkeys} /opt/heartbeat/etc/ha.d/
        .mv /etc/init.d/*csmail* /opt/heartbeat/etc/ha.d/resource.d/
    c.三个文件配置
        .ha.cf文件
            use_logd yes
            debugfile /var/log/rhythmha-debug
            logfile /var/log/rhythmha-log
            logfacility    local0
            udpport 694
            keepalive 2
            deadtime 30
            warntime 10
            initdead 120
            hopfudge 1
            ucast eth0 192.168.0.21
            auto_failback off 
            node    csmail_ha1 csmail_ha2
        .haresources文件
            csmail_ha1 192.168.0.20 rhythmha_mount httpd mysql.server.csmail mysql.server.front.csmail csmail.rc rhythmha_report
        .authkeys文件
            auth 1
            1 crc
            2 sha1 HI!
            3 md5 Hello!
5，启动测试
