编译安装问题:

1../configure

Keepalived configuration

------------------------

Keepalived version : 1.1.15

Compiler : gcc

Compiler flags : -g -O2

Extra Lib : -lpopt -lssl -lcrypto

Use IPVS Framework : Yes

IPVS sync daemon support : Yes

Use VRRP Framework : Yes

Use LinkWatch : No

Use Debug flags : No

如果Use IPVS Framework 为No 则使用keepalived启用后将无法条用ipvsadm,所以

安装时需要指定kernel:

./configure --with-kernel-dir=/usr/src/kernels/2.6.18-194.32.1.el5-i686

ü 2. Can not include OpenSSL
!!! OpenSSL is not properly installed on your system. !!!
  !!! Can not include OpenSSL headers files.            !!!

提示open-ssl未安装:yum openssl-devel

ü .make时出现如下乱码错误:

check_http.c:459: 警告:对指针赋值时目标与指针有/无符号不一致

check_http.c:461: 警告:传递参数 1 (属于 ‘sprintf’) 给指针时目标与指针有/无符号不一致

check_http.c:463: 警告:传递参数 1 (属于 ‘strlen’) 给指针时目标与指针有/无符号不一致

check_http.c:463: 警告:传递参数 2 (属于 ‘__builtin_strcmp’) 给指针时目标与指针有/无符号不一致

check_http.c:463: 警告:传递参数 2 (属于 ‘__builtin_strcmp’) 给指针时目标与指针有/无符号不一致

check_http.c:463: 警告:传递参数 1 (属于 ‘strlen’) 给指针时目标与指针有/无符号不一致

check_http.c:463: 警告:传递参数 2 (属于 ‘__builtin_strcmp’) 给指针时目标与指针有/无符号不一致

check_http.c:463: 警告:传递参数 2 (属于 ‘__builtin_strcmp’) 给指针时目标与指针有/无符号不一致

尽量保持kernel版本一致,如:

[root@hbchen ~]# rpm -qa|grep kernel

kernel-2.6.18-164.el5

kernel-headers-2.6.18-164.el5

kernel-devel-2.6.18-164.el5

(keepalived对于一些kernel不兼容,所以kernel都要保持一致,Version 1.1.19以下的版本都兼容性比较好,

所以安装1.1.19以上的版本make时会出现很多乱七八糟的错误)

注意下这里2.6.18-194.32.1.el5-i686要替换为你自己系统的核心,用uname -r 查询

解决方法:yum install kernel-devel

ln -s /usr/src/kernels/2.6.9-22.EL-i686/ /usr/src/linux

ü ip_vs文件错误

/usr/include/sys/types.h:62: 错误:与 ‘dev_t’ 类型冲突

/usr/src/kernels/2.6.18-194.3.1.el5-i686/include/linux/types.h:22: 错误:‘dev_t’ 的上一个声明在此

/usr/include/sys/types.h:67: 错误:与 ‘gid_t’ 类型冲突

/usr/src/kernels/2.6.18-194.3.1.el5-i686/include/linux/types.h:54: 错误:‘gid_t’ 的上一个声明在此

/usr/include/sys/types.h:72: 错误:与 ‘mode_t’ 类型冲突

/usr/src/kernels/2.6.18-194.3.1.el5-i686/include/linux/types.h:24: 错误:‘mode_t’ 的上一个声明在此

/usr/include/sys/types.h:77: 错误:与 ‘nlink_t’ 类型冲突

/usr/src/kernels/2.6.18-194.3.1.el5-i686/include/linux/types.h:25: 错误:‘nlink_t’ 的上一个声明在此

/usr/include/sys/types.h:82: 错误:与 ‘uid_t’ 类型冲突

/usr/src/kernels/2.6.18-194.3.1.el5-i686/include/linux/types.h:53: 错误:‘uid_t’ 的上一个声明

.找到ip_vs.h文件.

find / -name ip_vs.h copy to /usr/include/net下

[root@hbchen /]# cp /usr/src/kernels/2.6.18-164.el5-i686/include/net/ip_vs.h /usr/include/net/

/usr/src/kernels/2.6.18-194.32.1.el5-i686/include/net/ip_vs.h 这个是我系统上的路径,

2.6.18-194.32.1.el5-i686要替换为你自己系统的核心没有这个路径的话用find命令查找

find / -name ip_vs.h (若找不到这个文件,你先要先把kernel-devel 安装好)

ü 加载ipvs模块

3.实现lvs群集的两个重要部件是ipvs内核模块和ipvsadm工具包。当前内核版本的系统已经包含ipvs内核模块,

但默认并没有加载到内核中,可以手工加载或安装ipvsadm之后会被加载。使用modprobe命令手工加载ipvs模块

并查询模块是否加

[root@hbchen ~]# modprobe ip_vs

[root@hbchen ~]# lsmod |grep ip_vs

ip_vs_wlc 6080 1

ü Keepalived_vrrp不生效

在/var/log/messages中Keepalived_vrrp不生效,即无vrrp日志

Nov 23 17:46:41 SN2008-06-070 Keepalived_vrrp: receive an invalid ip number count associated with VRID!

Nov 23 17:46:41 SN2008-06-070 Keepalived_vrrp: bogus VRRP packet received on eth0 !!!

重新编译源码包,可能是由于修改types.h后才configure

Ipvsadm启动问题

Ipvsadm可以通过脚本直接启动不用启动服务(service ipvsadm start)

若要直接启动,报错如下:

Applying IPVS configuration: /etc/init.d/ipvsadm: line 62: /etc/sysconfig/ipvsadm: 没有那个文件或目录

[失败]

[root@localhost init.d]# service ipvsadm save

Saving IPVS table to /etc/sysconfig/ipvsadm: [确定]

[root@localhost init.d]# service ipvsadm start

Clearing the current IPVS table: [确定]

Applying IPVS configuration: [确定]

此时只需要保存ipvsadm表即可!(service ipvsadm save)
