LVS的安装部署

系统必须有ip_vs模块

#查看ip_vs模块
[root@node1 ~]# lsmod |grep -i ip_vs
ip_vs_rr               12600  1 
ip_vs                 141432  3 ip_vs_rr
nf_conntrack          133053  7 ip_vs,nf_nat,nf_nat_ipv4,nf_nat_ipv6,xt_conntrack,nf_conntrack_ipv4,nf_conntrack_ipv6
libcrc32c              12644  4 xfs,ip_vs,nf_nat,nf_conntrack
#没有，加载ip_vs
[root@node1 ~]# modprobe ip_vs

一、LVS的安装

1、yum安装

#1、安装清华的epel源
#2、安装ipvadm
yum install -y ipvsadm

2、源码包安装

#https://mirrors.edge.kernel.org/pub/linux/utils/kernel/ipvsadm/选择与内核相同版本的软件
mkdir -p /server/tools
cd /server/tools
wget -c https://mirrors.edge.kernel.org/pub/linux/utils/kernel/ipvsadm/ipvsadm-1.30.tar.xz
ln -s /usr/src/kernels/3.10.0-1062.18.1.el7.x86_64/ /usr/src/linux
tar xzvf ipvsadm-1.30.tar.gz 
cd ipvsadm-1.30
make 
make install
#如果编译报错，请安装依赖包
#yum install -y popt-static kernel-devel make gcc openssl-devel lftplibnl* popt* openssl-devel lftplibnl* popt* libnl* libpopt* gcc*
