  前端用两台server做lvs+keepalived负载调度器,中间用apache+php作为web应用服务器,后端用两台做mysql高可用,用nfs、mfs或作为web文件共享服务器
系统环境:LVS调度主服务器:192.168.8.11LVS调度从服务器:192.168.8.12LVS VIP:192.168.8.10apache服务器:192.168.8.20  192.168.8.21MySQL主服务器:192.168.8.31MySQL从服务器:192.168.8.32MySQL VIP:192.168.8.30由于工作时间比较紧,同时还要培训,架构图后期补上!!用到软件准备:所有服务器软件包都放在/opt 目录下,下面是下载地址:

  •   wget http://www.keepalived.org/software/keepalived-1.1.20.tar.gz
  •   wget http://downloads.mysql.com/archives/mysql-5.5/mysql-5.5.24-linux2.6-x86_64.tar.gz  #64位
  •   wget http://downloads.mysql.com/archives/mysql-5.5/mysql-5.5.24-linux2.6-i686.tar.gz    #32位
一、LVS+Keepalived1.安装ipvsadmyum -y install ipvsadm kernel-develln -sv /usr/src/kernels/2.6.18-308.8.2.el5-x86_64/ /usr/src/linux2.安装keepalived

  •   cd /opt/
  •   tar zxf keepalived-1.1.20.tar.gz
  •   cd keepalived-1.1.20
  •   ./configure --prefix=/usr/local/keepalived --with-kernel-dir=/usr/src/kernels/2.6.18-308.11.1.el5-x86_64/
  •   出现如下信息内核加载成功:
  •   Keepalived configuration
  •   ------------------------
  •   Keepalived version       : 1.1.20
  •   Compiler                 : gcc
  •   Compiler flags           : -g -O2
  •   Extra Lib                : -lpopt -lssl -lcrypto
  •   Use IPVS Framework       : Yes
  •   IPVS sync daemon support : Yes
  •   Use VRRP Framework       : Yes
  •   Use Debug flags          : No
  •   make;make install
  •   cp /usr/local/keepalived/etc/rc.d/init.d/keepalived /etc/rc.d/init.d
  •   cp /usr/local/keepalived/etc/sysconfig/keepalived /etc/sysconfig/
  •   mkdir /etc/keepalived
  •   chkconfig keepalived on
3.创建配置文件

  •   cat /etc/keepalived/keepalived.conf
  •   ! Configuration File for keepalived
  •   global_defs {
  •   notification_email {
  •   250621008@qq.com
  •   }
  •   notification_email_from 250621008@qq.com
  •   smtp_server smtp.163.com
  •   #smtp_connect_timeout 30
  •   router_id LVS_DEVEL
  •   }
  •   vrrp_instance VI_1 {
  •   state MASTER             #备份服务器上将MASTER改为BACKUP
  •   interface eth0
  •   lvs_sync_daemon_inteface eth0
  •   virtual_router_id 51
  •   priority 100        #备份服务上将100改为低于100的数值
  •   advert_int 5
  •   authentication {
  •   auth_type PASS
  •   auth_pass 1111
  •   }
  •   virtual_ipaddress {
  •   192.168.8.10
  •   }
  •   }
  •   virtual_server 192.168.8.10 80 {
  •   delay_loop 6                  #(每隔10秒查询realserver状态)
  •   lb_algo wlc                   #(lvs 算法)
  •   lb_kind DR                    #(Direct Route)
  •   persistence_timeout 60        #(同一IP的连接60秒内被分配到同一台realserver)
  •   protocol TCP                  #(用TCP协议检查realserver状态)
  •   real_server 192.168.8.11 80 {
  •   weight 100                #(权重)
  •   TCP_CHECK {
  •   connect_timeout 10        #(10秒无响应超时)
  •   nb_get_retry 3
  •   delay_before_retry 3
  •   connect_port 80
  •   }
  •   }
  •   real_server 192.168.8.12 80 {
  •   weight 100
  •   TCP_CHECK {
  •   connect_timeout 10
  •   nb_get_retry 3
  •   delay_before_retry 3
  •   connect_port 80
  •   }
  •   }
  •   }
PS :从配置文件参考以上主的配置文件,不同的地方是红色标注两处!二、WEB集群1、这里可以选择lamp、lnmp、lanmp等web架构,至于搭建略!2、在各web节点上创建realserver脚本

  •   cat /root/sh/lvs_real.sh
  •   #!/bin/bash
  •   #Description: Config realserver script
  •   #Written by : opsren----http://linuxops.blog.51cto.com
  •   SNS_VIP=192.168.8.10
  •   /etc/rc.d/init.d/functions
  •   case"$1"in
  •   start)
  •   /sbin/ifconfig lo:0 $SNS_VIP netmask 255.255.255.255 broadcast $SNS_VIP
  •   /sbin/route add -host $SNS_VIP dev lo:0
  •   echo "1" >/proc/sys/net/ipv4/conf/lo/arp_ignore
  •   echo "2" >/proc/sys/net/ipv4/conf/lo/arp_announce
  •   echo "1" >/proc/sys/net/ipv4/conf/all/arp_ignore
  •   echo "2" >/proc/sys/net/ipv4/conf/all/arp_announce
  •   sysctl -p >/dev/null 2>&1
  •   echo "RealServer Start OK"
  •   ;;
  •   stop)
  •   /sbin/ifconfig lo:0 down
  •   /sbin/route del $SNS_VIP >/dev/null 2>&1
  •   echo "0" >/proc/sys/net/ipv4/conf/lo/arp_ignore
  •   echo "0" >/proc/sys/net/ipv4/conf/lo/arp_announce
  •   echo "0" >/proc/sys/net/ipv4/conf/all/arp_ignore
  •   echo "0" >/proc/sys/net/ipv4/conf/all/arp_announce
  •   echo "RealServer Stoped"
  •   ;;
  •   *)
  •   echo "Usage: $0 {start|stop}"
  •   exit 1
  •   esac
  •   exit 0
  •   给予可执行权限:
  •   chmod +755 /roo/sh/lvs_real.sh
  •   启动脚本:
  •   /root/sh/lvs_real.sh start
三、MySQL高可用(双主)部署1.MySQL安装与配置这里采用mysql5.5.24二进制tar包tar zxf mysql-5.5.24-linux2.6-x86_64.tar.gz -C /usr/local/mysql5.5设置配置文件:

注意两点:1).在两台MySQL服务器上开启bin-log日志,默认是开启的!2).另外一台服务器节点的server-id设置为20,本来设置为102.将31服务器设置32的主服务器在31服务器上建立授权用户!

4.主主同步测试先在31服务器上建个库:

  •   mysql> create database t_test;
  •   Query OK, 1 row affected (0.03 sec)
  •   mysql> show databases;
  •   +--------------------+
  •   | Database           |
  •   +--------------------+
  •   | information_schema |
  •   | mysql              |
  •   | performance_schema |
  •   | t_test             |
  •   | test               |
  •   +--------------------+
  •   5 rows in set (0.00 sec)
  •   再到32服务器查询是否同步过来这个库:
  •   mysql> show databases;
  •   +--------------------+
  •   | Database           |
  •   +--------------------+
  •   | information_schema |
  •   | bbs                |
  •   | mysql              |
  •   | performance_schema |
  •   | t_test             |
  •   | test               |
  •   +--------------------+
  •   6 rows in set (0.00 sec)
  •   可以看到同步过来了!
  •   反过来一样!这步略!
  •   5.keepalived安装配置

主备配置文件注意几点:1).router_id 两边必须相同2).state 两边都为BACKUP3).virtual_router_id 两边必须相同4).priority 主节点的值必须大于从节点的值5).nopreempt 不抢占,只在priority高的节点(即主节点)上设置6).real_server 只需要本机的IP,不需要其它节点的!7).notify_down 作用是监测到当mysql停止工作时自动关闭本机的keepalived的脚本,实现故障转移!在主从上都创建当mysql停止工作时自动关闭本机的keepalived的脚本:

  •   cat /root/sh/mysql.sh
  •   #!/bin/bash
  •   MYSQL=/usr/local/mysql/bin/mysql
  •   MYSQL_HOST=localhost
  •   MYSQL_USER=root
  •   MYSQL_PASSWORD="admin"
  •   CHECK_TIME=3

  •   #mysql is working MYSQL_OK is 0 , mysql down MYSQL_OK is 1
  •   MYSQL_OK=1
  •   function check_mysql_helth (){
  •   $MYSQL -h $MYSQL_HOST -u $MYSQL_USER -p $MYSQL_PASSWORD -e "show status;" > /dev/null 2>&1
  •   if [ $? = 0 ] ;then
  •   MYSQL_OK=0
  •   else
  •   MYSQL_OK=1
  •   fi
  •   return $MYSQL_OK
  •   }
  •   while [ $CHECK_TIME -ne 0 ]
  •   do
  •   let "CHECK_TIME -= 1"
  •   check_mysql_helth
  •   if [ $MYSQL_OK = 0 ] ; then
  •   CHECK_TIME=0
  •   exit 0
  •   fi
  •   if [ $MYSQL_OK -eq 1 ] && [ $CHECK_TIME -eq 1 ]
  •   then
  •   /etc/init.d/keepalived stop
  •   exit 1
  •   fi
  •   sleep 1
  •   done
6.故障转移测试分别启动主备节点的keepalived服务,然后在主节点查看VIP有没有启动:

  •   31服务器:
  •   [root@mysql1 ~]# ip a |grep eth0
  •   2: eth0:  mtu 1500 qdisc pfifo_fast qlen 1000
  •   inet 192.168.8.31/24 brd 192.168.8.255 scope global eth0
  •   inet 192.168.8.30/32 scope global eth0
  •   32服务器:
  •   [root@mysql2 keepalived-1.1.19]# ip a |grep eth0
  •   2: eth0:  mtu 1500 qdisc pfifo_fast qlen 1000
  •   inet 192.168.8.32/24 brd 192.168.8.255 scope global eth0
  •   现在把31服务器的mysql服务停掉:
  •   [root@mysql1 keepalived]# ip a
  •   1: lo:  mtu 16436 qdisc noqueue
  •   link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
  •   inet 127.0.0.1/8 scope host lo
  •   2: eth0:  mtu 1500 qdisc pfifo_fast qlen 1000
  •   link/ether 00:0c:29:d4:fd:b3 brd ff:ff:ff:ff:ff:ff
  •   inet 192.168.8.31/24 brd 192.168.8.255 scope global eth0
  •   inet 192.168.8.30/32 scope global eth0
  •   [root@mysql1 keepalived]# service mysqld stop
  •   Shutting down MySQL.                                       [  OK  ]
  •   [root@mysql1 keepalived]# service keepalived status
  •   keepalived is stopped
  •   [root@mysql1 keepalived]#
可以看到mysql服务停掉后,keepalived服务也马上停掉了!再到32节点上查看下VIP有没有接管:[root@mysql2 ~]# ip a1: lo:  mtu 16436 qdisc noqueue     link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00    inet 127.0.0.1/8 scope host lo2: eth0:  mtu 1500 qdisc pfifo_fast qlen 1000    link/ether 00:0c:29:e3:dd:5a brd ff:ff:ff:ff:ff:ff    inet 192.168.8.32/24 brd 192.168.8.255 scope global eth0    inet 192.168.8.30/32 scope global eth0可以看到接管过来了!四、存储部分请参考笔者的相关文章:http://linuxops.blog.51cto.com/2238445/895945  --mfs分布式存储(这里修正了几个错误!!!)http://linuxops.blog.51cto.com/2238445/899652  --第五部分:NFS高可用web存储部署
