先上一个图,在内网测试机上安装了一个虚拟机,已经安装好了CentOS
乖乖连wget都没有安装,先安装wget吧
sudo yum install wget
下载LVS
wget http://www.linuxvirtualserver.org/software/kernel-2.6/ipvsadm-1.26.tar.gz
解压
tar zxvf ipvsadm-1.26.tar.gz
cd ipvsadm-1.26
make && make install
make -C libipvs make[1]: Entering directory `/root/ipvsadm-1.26/libipvs‘ gcc -Wall -Wunused -Wstrict-prototypes -g -fPIC -DLIBIPVS_USE_NL -DHAVE_NET_IP_VS_H -c -o libipvs.o libipvs.c make[1]: gcc: Command not found make[1]: *** [libipvs.o] Error 127 make[1]: Leaving directory `/root/ipvsadm-1.26/libipvs‘ make: *** [libs] Error 2
出错了,原来是没有找到gcc 哪么安装gcc吧
yum install gcc
Complete! 安装成功再使用
make && make install
又出错了
libipvs.c:1051: error: ‘NL_OK’ undeclared (first use in this function) libipvs.c: In function ‘ipvs_get_daemon’: libipvs.c:1071: error: ‘NLM_F_DUMP’ undeclared (first use in this function) libipvs.c:1072: error: too many arguments to function ‘ipvs_nl_send_message’ make[1]: *** [libipvs.o] Error 1 make[1]: Leaving directory `/root/ipvsadm-1.26/libipvs‘ make: *** [libs] Error 2
看看象是lib类型库的问题,安装以后库
yum install libnl*
make ipvsadm.c:114:18: error: popt.h: No such file or directory ipvsadm.c: In function ‘parse_options’: ipvsadm.c:365: error: ‘poptContext’ undeclared (first use in this function) ipvsadm.c:365: error: (Each undeclared identifier is reported only once ipvsadm.c:365: error: for each function it appears in.) ipvsadm.c:365: error: expected ‘;’ before ‘context’ ipvsadm.c:367: error: array type has incomplete element type ipvsadm.c:368: error: ‘POPT_ARG_NONE’ undeclared (first use in this function) ipvsadm.c:383: error: ‘POPT_ARG_STRING’ undeclared (first use in this function) ipvsadm.c:394: error: ‘POPT_ARGFLAG_OPTIONAL’ undeclared (first use in this function) ipvsadm.c:432: error: ‘context’ undeclared (first use in this function) ipvsadm.c:432: warning: implicit declaration of function ‘poptGetContext’ ipvsadm.c:435: warning: implicit declaration of function ‘poptGetNextOpt’ ipvsadm.c:661: warning: implicit declaration of function ‘poptBadOption’ ipvsadm.c:661: error: ‘POPT_BADOPTION_NOALIAS’ undeclared (first use in this function) ipvsadm.c:669: warning: implicit declaration of function ‘poptStrerror’ ipvsadm.c:670: warning: implicit declaration of function ‘poptFreeContext’ ipvsadm.c:677: warning: implicit declaration of function ‘poptGetArg’ ipvsadm.c:367: warning: unused variable ‘options_table’ make: *** [ipvsadm.o] Error 1
又出现了新问题,看起来像是popt类型库的问题
yum install popt*
make && make install
安装成功!
接下来安装 Keepalived
下载
wget http://www.keepalived.org/software/keepalived-1.2.4.tar.gz
tar zxvf keepalived-1.2.4.tar.gz
cd keepalived-1.2.4
./configrue
!!! OpenSSL is not properly installed on your system. !!!
原来是OpenSSL没有安装,哪么安装OpenSSL吧
yum install openssl-devel
再次 ./configure 成功
Keepalived configuration ------------------------ Keepalived version : 1.2.4 Compiler : gcc Compiler flags : -g -O2 Extra Lib : -lpopt -lssl -lcrypto -lnl Use IPVS Framework : Yes IPVS sync daemon support : Yes IPVS use libnl : Yes Use VRRP Framework : Yes Use VRRP VMAC : Yes Use Debug flags : No
开始安装Keepalived
make && make install
安装成功
make -C genhash install make[1]: Entering directory `/root/keepalived-1.2.4/genhash‘ install -d /usr/local/bin install -m 755 ../bin/genhash /usr/local/bin/ install -d /usr/local/share/man/man1 install -m 644 ../doc/man/man1/genhash.1 /usr/local/share/man/man1 make[1]: Leaving directory `/root/keepalived-1.2.4/genhash‘
开启路由转发
vi /etc/sysctl.conf
将
net.ipv4.ip_forward = 0
修改成
net.ipv4.ip_forward = 1
:wq保存
刷新一下系统变量,使配置值生效
sysctl -p
net.ipv4.ip_forward = 1
看到了输出变量为1
接下来
配置Real Server
由于我们的Real Server是windows2008主机
需要增加一个虚拟网卡
配置网卡地址为
192.168.1.14
子网掩码为
255.255.255.255
