LVS 进阶配置

以下内容的maste为172.16.1.134，RS1为192.168.1.111，RS2为192.168.1.112

使用防火墙标记

  1. （测试）为RS1和RS2配置HTTPS
[root@master ~]\# cd /etc/pki/CA/
[root@master CA]\# ls
certs  crl  newcerts  private
# 生成私钥
[root@master CA]\# (umask 077;openssl genrsa -out private/cakey.pem 2048) 
Generating RSA private key, 2048 bit long modulus
...+++
.............................................................................................+++
e is 65537 (0x10001)
# 生成自签证书
[root@master CA]\# openssl req -new -x509 -key private/cakey.pem -out cacert.pem -days 365
[root@master CA]\# touch index.txt
[root@master CA]\# echo 01 > serial

[root@master ~]\# cd /etc/pki/CA/
[root@master CA]\# ls

[root@master ~]\# openssl ca -in https.csr -out https.crt -days 365

# node01生成私钥

  1. 添加防火墙标记
[root@master ~]\# iptables -t mangle -A PREROUTING -d 172.16.1.134 -p tcp -m multiport --dport 80,443 -j MARK --set-mark 2

[root@master ~]\# iptables -t mangle -A PREROUTING -d 172.16.1.134 -p tcp -m multiport --dport 80,443 -j MARK --set-mark 2
  1. 添加规则
[root@master ~]\# ipvsadm -C
[root@master ~]\# ipvsadm -A -f 2 -s sh
[root@master ~]\# ipvsadm -a -f 2 -r  192.168.1.111 -m  
[root@master ~]\# ipvsadm -a -f 2 -r  192.168.1.112 -m
[root@master ~]\# ipvsadm -Ln
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags
  -> RemoteAddress:Port           Forward Weight ActiveConn InActConn
FWM  2 sh
  -> 192.168.1.111:0              Masq    1      0          0         
  -> 192.168.1.112:0              Masq    1      0          0         

[root@master ~]\# ipvsadm -C
[root@master ~]\# ipvsadm -A -f 2 -s sh
[root@master ~]\# ipvsadm -a -f 2 -r  192.168.1.111 -m  
[root@master ~]\# ipvsadm -a -f 2 -r  192.168.1.112 -m
[root@master ~]\# ipvsadm -Ln
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags
  -> RemoteAddress:Port           Forward Weight ActiveConn InActConn
FWM  2 sh
  -> 192.168.1.111:0              Masq    1      0          0         
  -> 192.168.1.112:0              Masq    1      0          0
  1. 测试
[root@master ~]\# curl https://172.16.1.134 --cacert /etc/pki/CA/cacert.pem 
<h1>Backend RS2 192.168.1.112</h1>

[root@master ~]\# curl https://172.16.1.134 --cacert /etc/pki/CA/cacert.pem 
<h1>Backend RS2 192.168.1.112</h1>

使用ldirectord

  1. 安装ldirectord
[root@master ~]\# yum install -y http://rpmfind.net/linux/mageia/distrib/4/x86_64/media/core/release/ldirectord-3.9.5-2.mga3.x86_64.rpm

[root@master ~]\# yum install -y http://rpmfind.net/linux/mageia/distrib/4/x86_64/media/core/release/ldirectord-3.9.5-2.mga3.x86_64.rpm
