Linux下的LVS,Apache,resin配置负载均衡
1.需要准备的硬件和安装的软件.
192.168.1.128安装LVS虚拟服务器。
192.168.1.126安装一个Apache和3个resin,LVS真实服务器
192.168.1.127安装一个Apache和3个resin，LVS真实服务器
2.先在126上进行安装
3.安装Apache.
$tarzxvfhttpd-2.2.*.tar.gz
$cdhttpd-2.2.*
$./configure--prefix=/usr/local/apache2-enable-mods-shared=all--enable-so
$make
$makeinstall
4.安装resin
$tarzxvfresin-3.1.*.tar.gz
$cdresin-3.1.*
$./configure--prefix=/usr/local/resina--with-apxs=/usr/local/apache2/bin/apxs
$make
$makeinstall
$tarzxvfresin-3.0.23.tar.gz
$cdresin-3.0.23
$./configure--prefix=/usr/local/resinb--with-apxs=/usr/local/apache2/bin/apxs
$make
$makeinstall
$tarzxvfresin-3.1.*.tar.gz
$cdresin-3.1.*
$./configure--prefix=/usr/local/resinb--with-apxs=/usr/local/apache2/bin/apxs
$make
$makeinstall
4.修改http.conf配置文件
在最后增加如下内容:
LoadModulecaucho_module/usr/local/apache2/modules/mod_caucho.so
ResinConfigServerlocalhost6801
ResinConfigServerlocalhost6802
ResinConfigServerlocalhost6803
CauchoConfigCacheDirectory/tmp
CauchoStatusyes
5.配置resina,resinb,resinc的resin.conf文件
三个配置文件修改成一样的.
注释掉默认的8080端口
<server-default>
<!--Thehttpport-->
<!--<httpaddress="*"port="8080"/>-->
找到<!--definetheserversinthecluster-->一行，改为如下内容：
<serverid="a"address="127.0.0.1"port="6801"/>
<serverid="b"address="127.0.0.1"port="6802"/>
<serverid="c"address="127.0.0.1"port="6803"/>
6.启动Apache进行验证：
/usr/local/apache2/bin/apachectlstart
7.启动三个resin
$cd/usr/local/resina/bin
$httpd.sh-serverastart
启动resinb
$cd/usr/local/resina/bin
$httpd.sh-serverbstart
启动resinc
$cd/usr/local/resinc/bin
$httpd.sh-servercstart
8.停止Apache和Resin
/usr/local/apache2/bin/apachectlstop
$cd/usr/local/resina/bin
$httpd.sh-serverastop
启动resinb
$cd/usr/local/resina/bin
$httpd.sh-serverbstop
启动resinc
$cd/usr/local/resinc/bin
$httpd.sh-servercstop
9.192.168.1.127也是这样安装。
10.安装LVS
在192.168.1.128运行如下脚本命令：
#description:startLVSofDirectorserver
VIP=192.168.1.130
RIP1=192.168.1.126
RIP2=192.168.1.127
GW=192.168.1.1
./etc/rc.d/init.d/functions
case"$1"in
start)
echo"startLVSofDirectorServer"
#settheVirtualIPAddress
/sbin/ifconfigeth0:0$VIPbroadcast$VIPnetmask255.255.255.255up
/sbin/routeadd-host$VIPdeveth0:0
#ClearIPVStable
/sbin/ipvsadm-C
#setLVS
/sbin/ipvsadm-A-t$VIP:80-srr
/sbin/ipvsadm-a-t$VIP:80-r$RIP1:80-g
/sbin/ipvsadm-a-t$VIP:80-r$RIP2:80-g
#RunLVS
/sbin/ipvsadm
#end
;;
stop)
echo"closeLVSDirectorserver"
/sbin/ipvsadm-C
;;
*)
echo"Usage:$0{start|stop}"
exit1
esac
在192.168.1.126和192.168.1.127下运行如下脚本命令：
#!/bin/bash
#description:startrealserver
VIP=192.168.1.130
/sbin/ifconfiglo:0$VIPbroadcast$VIPnetmask255.255.255.255up
/sbin/routeadd-host$VIPdevlo: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
#end
在浏览器中输入http://192.168.1.130就通过LVS转发到127和126两台不同的服务器上。
在通过Apache分发到不同的Resin服务器上.
