lvs+keepalived离线安装包安装

一、ipvsadm安装

1，安装环境centos7.0内核3.10.0-327.el7.x86_64 。需安装gcc
[root@localhost ~]# yum -y install gcc

未避免安装过程安全其他依赖，可在安装系统时选择如下几个组件：

2，下载ipvsadm安装包（下载1.27版本）

https://kernel.org/pub/linux/utils/kernel/ipvsadm/

3，解压、编译、安装
[root@localhost ~]# tar -Jxvf ipvsadm-1.27.tar.xz
[root@localhost ~]# cd ipvsadm-1.27
[root@localhost ipvsadm-1.27]# make && make install
4，可能出现如下错误：
[root@localhost ipvsadm-1.27]# make &make install

解决方法是安装如下软件：

[root@localhost ipvsadm-1.27]# yum installpopt-static
[root@localhost ipvsadm-1.27]# yum installlibnl* libpopt*

 

二、keepalived安装

1）软件下载（下载1.2.13版本）

http://www.keepalived.org/software/

2）解压、配置、编译、安装
[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）编译时可能会出现如下错误1
configure: error:
  !!!OpenSSL is not properly installed on your system. !!!
  !!!Can not include OpenSSL headers files.            !!!

解决方法：

[root@localhost keepalived-1.2.13]# yuminstall -y openssl openssl-devel

 

4）编译过程可能会出现如下错误2
[root@localhost keepalived-1.2.13]# make
make -C lib || exit 1;
make[1]: Entering directory`/root/keepalived-1.2.13/lib'

make: *** [all] Error 2

解决方法：

去掉如下符号链接（之前配置符号链接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）启动服务并开启开机自启动
[root@localhost keepalived]# service keepalived
Usage: /etc/init.d/keepalived{start|stop|reload|restart|condrestart|status}
[root@localhost keepalived]# chkconfig keepalived on
8）启动可能出现如下错误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)

Aug 31 07:22:19 localhost.localdomainsystemd[1]: keepalived.service failed.

解决方法：

[root@localhost ~]# ln -s/usr/local/keepalived/sbin/keepalived /usr/sbin/

其中/usr/local/keepalived/为软件安装目录。
