MongoDB 数据库简单介绍（安装篇）

一、启动服务

1、在每台RS（真实服务器）上绑定LVS的虚拟IP及抑制ERP

[root@LVS_RS_104 ~]# /etc/rc.d/init.d/lvs_dr.sh start
RealServer Start OK
[root@LVS_DR_103 ~]# /etc/rc.d/init.d/lvs_dr.sh start
RealServer Start OK

2、启动LVS主的Keepalived服务 并查看日志 /var/log/messages

[root@LVS_Master_101 ~]# /etc/rc.d/init.d/keepalived start
正在启动 keepalived： [确定]
[root@LVS_Master_101 ~]# tail -f /var/log/messages

Jan 22 04:06:30 centos1 avahi-daemon[1261]: Registering new address record for 192.168.1.181 on eth0.IPv4.

3、启动备的Keeplived服务，，并查看日志

[root@LVS_Backup_114 ~]# /etc/rc.d/init.d/keepalived start
正在启动 keepalived： [确定]
[root@LVS_Backup_114 ~]# cat /var/log/messages
Jan 22 04:17:29 test Keepalived: Starting Keepalived v1.1.17 (01/13,2013)
Jan 22 04:17:29 test Keepalived: Starting Healthcheck child process, pid=1528
Jan 22 04:17:29 test Keepalived: Starting VRRP child process, pid=1529
Jan 22 04:17:29 test Keepalived_vrrp: Using MII-BMSR NIC polling thread...
Jan 22 04:17:29 test Keepalived_healthcheckers: Using MII-BMSR NIC polling thread...
Jan 22 04:17:29 test Keepalived_healthcheckers: Netlink reflector reports IP 192.168.1.114 added
Jan 22 04:17:29 test Keepalived_vrrp: Netlink reflector reports IP 192.168.1.114 added
Jan 22 04:17:29 test Keepalived_healthcheckers: Registering Kernel netlink reflector
Jan 22 04:17:29 test Keepalived_healthcheckers: Registering Kernel netlink command channel
Jan 22 04:17:29 test Keepalived_vrrp: Registering Kernel netlink reflector
Jan 22 04:17:29 test Keepalived_vrrp: Registering Kernel netlink command channel
Jan 22 04:17:29 test Keepalived_vrrp: Registering gratutious ARP shared channel
Jan 22 04:17:29 test Keepalived_vrrp: Opening file '/etc/keepalived/keepalived.conf'. #打开Keepalived的主配置文件
Jan 22 04:17:29 test Keepalived_vrrp: Configuration is using : 62711 Bytes
Jan 22 04:17:29 test Keepalived_vrrp: VRRP_Instance(VI_1) Entering BACKUP STATE #进入备 角色
Jan 22 04:17:29 test Keepalived_vrrp: VRRP sockpool: [ifindex(2), proto(112), fd(10,11)]

4、使用ipvsadm -Ln查看状态

[root@LVS_Master_101 ~]# ipvsadm
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP 192.168.1.181:http rr persistent 50
-> 192.168.1.104:http Route 1 0 0
-> 192.168.1.103:http Route 1 0 0

如果输出和上面的一致表明 LVS + Keepalived安装配置成功。接下来测试负载均衡和高可用。
