LVS fullnat + ecmp [2] install keepalived + ipvsadm + quaage

1. Copy The LVS-tools compressed package

cd lvs-fullnat-synproxy/cp lvs-tools.tar.gz /home/pukongcd /home/pukong/tar xzf lvs-tools.tar.gz;

After decompression, there will be a tool folder.

2. Install keepalived

cd /home/pukong/tools/keepalived;yum -y install popt-devel openssl-devel./configure --with-kernel-dir="/lib/modules/`uname -r`/build";

After the previous step is executed, the following message appears, indicating that keepalived has been compiled successfully.

Then proceed to the next step.

make;make install;mkdir /etc/keepalived -pvcp -a bin/keepalived /sbin/cp -a keepalived/etc/init.d/keepalived.init /etc/init.d/keepalivedcp -a keepalived/etc/keepalived/keepalived.conf /etc/keepalivedcp -a keepalived/etc/init.d/keepalived.sysconfig /etc/sysconfig/keepalived

2.1 check whether keepalived is successfully installed

[[email protected] ~]# service keepalived statuskeepalived is stopped[[email protected] ~]# service keepalived startStarting keepalived:                                       [  OK  ][[email protected] ~]# service keepalived statuskeepalived (pid  9057) is running...[[email protected] ~]# 

3. Install ipvsadm

Note: ipvsadm must be installed in the compressed package, because ipvsadm In the yum source does not have the fullnat mode parameter.

cd /home/pukong/tools/ipvsadm;make;make install;

3.1 check whether ipvsadm is successfully installed

[[email protected] ipvsadm]# ipvsadm -lnIP Virtual Server version 1.2.1 (size=4194304)Prot LocalAddress:Port Scheduler Flags  -> RemoteAddress:Port           Forward Weight ActiveConn InActConnTCP  192.168.200.100:443 rr persistent 50TCP  10.10.10.2:1358 rr persistent 50  -> 192.168.200.200:1358         Masq    1      0          0         TCP  10.10.10.3:1358 rr persistent 50[[email protected] ipvsadm]# ipvsadm -h...... --ipip         -i                   ipip encapsulation (tunneling) --fullnat      -b                   fullnat mode --masquerading -m                   masquerading (NAT)......

The above ECHO is successful. However, some backend and some backend are not displayed because of configuration parameters. For more information, see the Configuration Guide of keepalived.
