centos7如何保存ipvsadm规则

一、部署环境keepalived:10.10.10.30(CentOS 7)lvs1:10.10.10.140(CentOS 6.4)lvs2:10.10.10.150(CentOS 6.4)二、在lvs1:10.10.10.140上配置# yum install -y httpd # /etc/init.d/httpd start# cd /var/www/html/# echo "ok" 》 keep.html # vim /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE=eth0HWADDR=00:0C:29:15:B7:DCTYPE=EthernetUUID=93f4695a-8641-4360-9fce-5e3af0e32fc9ONBOOT=yesNM_CONTROLLED=yesBOOTPROTO=staticIPADDR=10.10.10.140NETMASK=255.255.255.0GATEWAY=10.10.10.30#/etc/init.d/network restart#/sbin/ifconfig eth0:0 10.10.10.140 broadcast 10.10.10.255 netmask 255.255.255.255 up三、在lvs2:10.10.10.150上配置# yum install -y httpd # /etc/init.d/httpd start# cd /var/www/html/# echo "ok" 》 keep.html # vim /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE=eth0HWADDR=00:0C:29:0D:33:ACTYPE=EthernetUUID=e04f57dc-ef9d-4563-bfa4-9c8c1e8fc870ONBOOT=yesNM_CONTROLLED=noBOOTPROTO=staticIPADDR=10.10.10.150NETMASK=255.255.255.0GATEWAY=10.10.10.30#/etc/init.d/network restart#/sbin/ifconfig eth0:0 10.10.10.140 broadcast 10.10.10.255 netmask 255.255.255.255 up四、在keepalived:10.10.10.30上配置# vim /etc/sysconfig/network-scripts/ifcfg-eno33554984HWADDR=00:0C:29:DC:FE:1BTYPE=EthernetBOOTPROTO=staticDEFROUTE=yesPEERDNS=yesPEERROUTES=yesIPV4_FAILURE_FATAL=no#IPV6INIT=yes#IPV6_AUTOCONF=yes#IPV6_DEFROUTE=yes#IPV6_PEERDNS=yes#IPV6_PEERROUTES=yes#IPV6_FAILURE_FATAL=noNAME=eno33554984#UUID=56cae8b8-235f-471d-9051-2508ee149e48ONBOOT=yesNM_CONTROLLED=noIPADDR=10.10.10.30NETMASK=255.255.255.0# /etc/init.d/network restart# cd /data/keepalived/# tar zxvf keepalived-1.2.12.tar.gz # cd keepalived-1.2.12/# ./configure --prefix=/usr/local/keepalived# make # make install# ln -s /usr/local/keepalived/etc/keepalived/ /etc/# ln -s /usr/local/keepalived/etc/rc.d/init.d/keepalived /etc/init.d/# ln -s /usr/local/keepalived/etc/sysconfig/keepalived /etc/sysconfig/# ln -s /usr/local/keepalived/sbin/keepalived /usr/sbin/# cd##keepalived健康检查 HTTP_GET# /usr/local/keepalived/bin/genhash -s 10.10.10.140 -p 80 -u /keep.htmlMD5SUM = eff5bc1ef8ec9d03e640fc4370f5eacd# /usr/local/keepalived/bin/genhash -s 10.10.10.150 -p 80 -u /keep.htmlMD5SUM = eff5bc1ef8ec9d03e640fc4370f5eacd# vim /etc/keepalived/keepalived.conf !

安装ipvsadm时出现下面所示错误，请问该如何解决

在ipvsadm安装过程中出现以下错误，导致一直无法安装，在网上搜索了很久也没找到解决方法。# makemake -C libipvsmake: Entering directory `/var/tmp/ipvsadm-1.24/libipvs’gcc -Wall -Wunused -Wstrict-prototypes -g -O2 -I/usr/src/linux/include -DHAVE_NET_IP_VS_H -c -o libipvs.c:79: error: dereferencing pointer to incomplete type。。。。。。。libipvs.c:309: error: dereferencing pointer to incomplete typelibipvs.c:315: error: `IP_VS_SO_GET_DAEMON’ undeclared (first use in this function)libipvs.c: At top level:libipvs.c:33: error: storage size of `ipvs_info’ isn’t knownlibipvs.c:132: error: `IP_VS_SO_SET_DELDEST’ undeclared (first use in this function)make Error 2最后在官网的wiki上发现原来是无法在/usr/src/linux下找到内核源码，所以无法安装。# cd /usr/src# mkdir linux# rpm -ivh kernel-devel-2.6.18-164.el5.i686.rpm #/usr/src目录下出现kernels目录# cd kernels# ls2.6.18-164.el5-i686这个目录就是源码的位置，下边做一个链接# ln -s /usr/src/kernels/2.6.18-164.el5-i686 /usr/src/linux

linux ipvsadm 是什么，详解，谢谢！

• 做负载均衡的一个模块，具体可以参考：http://sapling.me/unixlinux/lvs.html符合要求，记得给分哦

• 是LVS linux虚拟服务的一个控制命令可以使用ipvsadmin来定义负载均衡分发策略，管理各个节点

在Ubuntu的lvs-ipvs (ipvsadm)中如何设定转发决定

ipvsadm只是一个管理ipvs的命令行工具，对于这2个要求：ipvsadm是可以办到的，在调用ipvs的命令中，选择源地址散列+目标地址散列调度结合使用即可。其中对于第二个要求：还可以结合管理ipvsadm的keepalived高可用软件还实现，具体实现的关键参数是sorry_server，然后real server就只设定一台。
