LVS+Keepalived安装配置故障排除

1.源码安装ipvsadm时报错：
make -C libipvs
make[1]: Entering directory `/root/ipvsadm-1.26/libipvs'
make[1]: Nothing to be done for `all'.
make[1]: Leaving directory `/root/ipvsadm-1.26/libipvs'
gcc -Wall -Wunused -Wstrict-prototypes -g -o ipvsadm ipvsadm.o config_stream.o dynamic_array.o libipvs/libipvs.a  -lnl

collect2: ld 返回 1
make: *** [ipvsadm] 错误 1

解决方法：
# rpm -ivh popt-static-1.13-7.el6.x86_64.rpm            

2.安装keepalived，  ./configure时报错： 
checking for sys/ioctl.h... yes
checking sys/time.h usability... yes
checking sys/time.h presence... yes
checking for sys/time.h... yes
checking openssl/ssl.h usability... no
checking openssl/ssl.h presence... no
checking for openssl/ssl.h... no
configure: error: 
  !!! OpenSSL is not properly installed on your system. !!!
  !!! Can not include OpenSSL headers files.            !!!

解决方法：
# yum install openssl-devel -y

3. keepalived, ./configure的结果
Keepalived configuration
------------------------
Keepalived version       : 1.2.0
Compiler                 : gcc
Compiler flags           : -g -O2
Extra Lib                : -lpopt -lssl -lcrypto 
Use IPVS Framework       : No          
IPVS sync daemon support : No
Use VRRP Framework       : Yes
Use Debug flags          : No

上面两条状态为No的话，将不支持lvs, 导致的结果是全部配置好后，ipvsadm -ln无论怎样都不显示结果。

解决方法：
./configure --with-kernel-dir=/usr/src/kernels/2.6.32-279.el6.x86_64/  
加上--with-kernel-dir选项，再重新configure
