安装keepalived遇到problem
-----------------------------新安装的干净centos---------------------------------------安装keepalived遇到的一些问题：
-------------------------------------------------------------------------------
1.更新yum源安装所需的库文件
yum install gcc* c++ * autoconf automake zlib*libxml* ncurses-devel libmcrypt*
libtool-ltdl-devel* popt-devel
-------------------------------------------------------------------------------
2.安装ipvsadm遇到如下错误：
make: *** Error 1
make: Leaving directory `/root/keepalived/ipvsadm-1.24/libipvs'
make: *** Error 2
-------------------------------------------------------------------------------
解决办法：
# yum install kernel-devel -y
# ln -s /usr/src/kernels/2.6.32-279.19.1.el6.i686/
/usr/src/linux
再次make如下：
# make
make -C libipvs
make: Entering directory `/root/keepalived/ipvsadm-1.24/libipvs'
gcc -Wall -Wunused -Wstrict-prototypes -g -O2 -I/usr/src/linux/include-
DHAVE_NET_IP_VS_H -c -o libipvs.o libipvs.c
ar rv libipvs.a libipvs.o
ar: creating libipvs.a
a - libipvs.o
make: Leaving directory `/root/keepalived/ipvsadm-1.24/libipvs'
gcc -Wall -Wunused -Wstrict-prototypes -g -O2 -I/usr/src/linux/include -I.. -I.
-DVERSION=\"1.24\" -DSCHEDULERS=\""rr|wrr|lc|wlc|lblc|lblcr|dh|sh|sed|nq"\"-
DHAVE_NET_IP_VS_H -c -o ipvsadm.o ipvsadm.c
gcc -Wall -Wunused -Wstrict-prototypes -g -O2 -I/usr/src/linux/include -I.. -I.
-DVERSION=\"1.24\" -DSCHEDULERS=\""rr|wrr|lc|wlc|lblc|lblcr|dh|sh|sed|nq"\"-
DHAVE_NET_IP_VS_H -c -o config_stream.o config_stream.c
gcc -Wall -Wunused -Wstrict-prototypes -g -O2 -I/usr/src/linux/include -I.. -I.
-DVERSION=\"1.24\" -DSCHEDULERS=\""rr|wrr|lc|wlc|lblc|lblcr|dh|sh|sed|nq"\"-
DHAVE_NET_IP_VS_H -c -o dynamic_array.o dynamic_array.c
gcc -Wall -Wunused -Wstrict-prototypes -g -O2 -o ipvsadm ipvsadm.o
config_stream.o dynamic_array.o libipvs/libipvs.a
make install 能顺利完成
------------------------------------------------------------------------------
3.安装keepalived遇到问题：
# ./configure --prefix=/usr/local/keepalived
出现：
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.
意思就是缺少openssl文件
-------------------------------------------------------------------------------
解决办法：
yum -y install openssl-devel*
再次执行
# ./configure --prefix=/usr/local/keepalived
成功！！！！
但是make时又出现错误
make: *** No targets specified and no makefile found. Stop.
将解压完的目录全部删除，重新编译又出现如下问题。
checking for SSL_CTX_new in -lssl... yes
checking for poptGetContext in -lpopt... no
configure: error: Popt libraries is required
解决办法：
# yum install popt-devel
出现如下：
Keepalived configuration
-------------------------------------------------------------------------------
Keepalived version : 1.2.7
Compiler : gcc
Compiler flags : -g -O2
Extra Lib : -lpopt -lssl -lcrypto
Use IPVS Framework : Yes
IPVS sync daemon support : Yes
IPVS use libnl : No（缺少lib文件）
Use VRRP Framework : Yes
Use VRRP VMAC : Yes
SNMP support : No
Use Debug flags : No
-------------------------------------------------------------------------------
解决办法：
# yum -y install libnl-devel
OK如下所示：
Keepalived configuration
------------------------
Keepalived version : 1.2.7
Compiler : gcc
Compiler flags : -g -O2
Extra Lib : -lpopt -lssl -lcrypto-lnl

cp /usr/local/keepalived/etc/rc.d/init.d/keepalived /etc/init.d/
cp /usr/local/keepalived/etc/sysconfig/keepalived/etc/sysconfig/
mkdir /etc/keepalived
mkdir -pv/etc/keepalived
mkdir -pv /etc/keepalived
cp /usr/local/keepalived/etc/keepalived/keepalived.conf/etc/keepalived/
ln -s /usr/local/keepalived/sbin/keepalived /sbin/
