lvs+keepalived離線安裝包安裝
一、ipvsadm安裝
1，安裝環境centos7.0內核3.10.0-327.el7.x86_64 。需安裝gcc
[root@localhost ~]# yum -y install gcc
未避免安裝過程安全其他依賴，可在安裝系統時選擇如下幾個組件：
2，下載ipvsadm安裝包（下載1.27版本）
https://kernel.org/pub/linux/utils/kernel/ipvsadm/
3，解壓、編譯、安裝
[root@localhost ~]# tar -Jxvf ipvsadm-1.27.tar.xz [root@localhost ~]# cd ipvsadm-1.27 [root@localhost ipvsadm-1.27]# make && make install
4，可能出現如下錯誤：
[root@localhost ipvsadm-1.27]# make &make install [1] 14264 make -C libipvs make -C libipvs make[1]: Entering directory`/root/ipvsadm-1.27/libipvs' gcc -Wall -Wunused -Wstrict-prototypes -g-fPIC -DLIBIPVS_USE_NL -DHAVE_NET_IP_VS_H -c -olibipvs.o libipvs.c make[1]: Entering directory`/root/ipvsadm-1.27/libipvs' gcc -Wall -Wunused -Wstrict-prototypes -g-fPIC -DLIBIPVS_USE_NL -DHAVE_NET_IP_VS_H -c -olibipvs.o libipvs.c In file included from libipvs.h:13:0, from libipvs.c:23: ip_vs.h:15:29: fatal error:netlink/netlink.h: No such file or directory #include <netlink/netlink.h> ^ compilation terminated. In file included from libipvs.h:13:0, from libipvs.c:23: ip_vs.h:15:29: fatal error:netlink/netlink.h: No such file or directory #include <netlink/netlink.h> ^ compilation terminated. make[1]: *** [libipvs.o] Error 1 make[1]: Leaving directory`/root/ipvsadm-1.27/libipvs' make: *** [libs] Error 2 make[1]: *** [libipvs.o] Error 1 make[1]: Leaving directory`/root/ipvsadm-1.27/libipvs' make: *** [libs] Error 2 [1]+ Exit 2 make
解決方法是安裝如下軟件：
[root@localhost ipvsadm-1.27]# yum installpopt-static [root@localhost ipvsadm-1.27]# yum installlibnl* libpopt*
二、keepalived安裝
1）軟件下載（下載1.2.13版本）
http://www.keepalived.org/software/
2）解壓、配置、編譯、安裝
[root@localhost ~]# tar -zxvf keepalived-1.2.13\ \(1\).tar.gz [root@localhost ~]# cd keepalived-1.2.13 [root@localhost keepalived-1.2.13]#./configure --prefix=/usr/local/keepalived [root@localhost keepalived-1.2.13]# make && make install
3）編譯時可能會出現如下錯誤1
configure: error: !!!OpenSSL is not properly installed on your system. !!! !!!Can not include OpenSSL headers files. !!!
解決方法：
[root@localhost keepalived-1.2.13]# yuminstall -y openssl openssl-devel
4）編譯過程可能會出現如下錯誤2
[root@localhost keepalived-1.2.13]# make make -C lib || exit 1; make[1]: Entering directory`/root/keepalived-1.2.13/lib' gcc -g -O2 -DFALLBACK_LIBNL1 -I. -Wall-Wunused -Wstrict-prototypes -D_WITHOUT_SNMP_ -c command.c make[1]: Leaving directory`/root/keepalived-1.2.13/lib' make -C keepalived make[1]: Entering directory`/root/keepalived-1.2.13/keepalived' make[2]: Entering directory`/root/keepalived-1.2.13/keepalived/core' gcc -g -O2 -DFALLBACK_LIBNL1 -I/usr/src/linux/include -I/usr/src/linux/include-I../include -I../../lib -Wall -Wunused -Wstrict-prototypes -D_KRNL_2_6_-D_WITH_LVS_ -D_WITH_VRRP_ -D_WITHOUT_SNMP_ -D_WITH_SO_MARK_ -c main.c gcc -g -O2 -DFALLBACK_LIBNL1 -I/usr/src/linux/include-I/usr/src/linux/include -I../include -I../../lib -Wall -Wunused-Wstrict-prototypes -D_KRNL_2_6_ -D_WITH_LVS_ -D_WITH_VRRP_ -D_WITHOUT_SNMP_-D_WITH_SO_MARK_ -c smtp.c In file included from/usr/include/linux/if_addr.h:4:0, from../include/vrrp_ipaddress.h:33, from ../include/vrrp.h:31, from ../include/smtp.h:34, from smtp.c:27: 。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。 /usr/src/linux/include/linux/linkage.h:7:25:fatal error: asm/linkage.h: No such file or directory #include <asm/linkage.h> ^ compilation terminated. make[2]: *** [smtp.o] Error 1 make[2]: Leaving directory`/root/keepalived-1.2.13/keepalived/core' make[1]: *** [all] Error 1 make[1]: Leaving directory`/root/keepalived-1.2.13/keepalived' make: *** [all] Error 2
解決方法：
去掉如下符號鏈接（之前配置符號鏈接ln -s /usr/src/kernels/3.10.0-229.el7.x86_64/ /usr/src/linux）
[root@localhost keepalived-1.2.13]# rm -rf /usr/src/linux
5）配置
[root@localhost keepalived]#cp /usr/local/keepalived/etc/rc.d/init.d/keepalived /etc/rc.d/init.d/ [root@localhost keepalived]#cp /usr/local/keepalived/etc/sysconfig/keepalived /etc/sysconfig/ [root@localhost keepalived]#mkdir /etc/keepalived [root@localhost keepalived]#cp /usr/local/keepalived/etc/keepalived/keepalived.conf /etc/keepalived/ [root@localhost keepalived]#cp /usr/local/keepalived/sbin/keepalived /usr/sbin/
6）修改配置文件
/etc/keepalived/keepalived.conf
7）啓動服務並開啓開機自啓動
[root@localhost keepalived]# service keepalived
Usage: /etc/init.d/keepalived{start|stop|reload|restart|condrestart|status}
[root@localhost keepalived]# chkconfig keepalived on8）啓動可能出現如下錯誤3
[root@localhost ~]# service keepalived status keepalived.service - SYSV:Start and stop Keepalived Loaded: loaded (/etc/rc.d/init.d/keepalived) Active: failed (Result: exit-code) since Wed 2016-08-31 07:22:19 EDT;5min ago Docs: man:systemd-sysv-generator(8) Process: 2405 ExecStart=/etc/rc.d/init.d/keepalived start (code=exited,status=1/FAILURE) Aug 31 07:22:19 localhost.localdomainsystemd[1]: Starting SYSV: Start and stop Keepalived...

解決方法：
[root@localhost ~]# ln -s/usr/local/keepalived/sbin/keepalived /usr/sbin/
其中/usr/local/keepalived/爲軟件安裝目錄。
