ubuntu搭建keepalived+haproxy高性能WEB服务器
ubuntu搭建keepalived+haproxy高性能WEB服务器一、架构拓扑图
haproxy
VIP：192.168.1.100
Master：192.168.1.10
Slave： 192.168.1.11
之间用keepalived实现HA
webserver1：192.168.1.101
webserver2：192.168.1.102
webserver3：192.168.1.103
二、安装keepalived和haproxy
sudo apt-get install keepalived
sudo apt-get install haproxy
三、配置haproxy
sudo vim /etc/haproxy/haproxy.cfg
加入下列内容
global
log 127.0.0.1 local1
maxconn 50000 #最大连接数
# chroot /usr/local/haproxy #安装目录
uid haproxy #用户haproxy
gid haproxy #组haproxy
daemon #守护进程运行
nbproc 1 #进程数量
pidfile /var/run/haproxy.pid #haproxy pid
defaults
log 127.0.0.1 local2
mode http #7层 http;4层tcp
optionhttplog #http 日志格式
optionhttpclose #主动关闭http通道
optionredispatch #强制定向到其他健康的服务器
optionforwardfor
optiondontlognull
maxconn 50000 #最大连接数
contimeout 5000 #连接超时(毫秒)
clitimeout 50000 #客户端超时(毫秒)
srvtimeout 50000 #服务器超时(毫秒)
# errorfile 400 /etc/haproxy/errors/400.http
# errorfile 403 /etc/haproxy/errors/403.http
# errorfile 408 /etc/haproxy/errors/408.http
# errorfile 500 /etc/haproxy/errors/500.http
# errorfile 502 /etc/haproxy/errors/502.http
# errorfile 503 /etc/haproxy/errors/503.http
# errorfile 504 /etc/haproxy/errors/504.http
#定义前端服务器
frontendweb #定义前端服务器(haproxy)
bind *:80 #监听地址
acl yxl_www hdr_beg(host) -i www. yinxiulei.cn
acl yxl_www hdr_beg(host) -i yinxiulei.cn
use_backend www. yinxiulei.cn if yinxiulei.cn
#定义后端服务器
backend www. yinxiulei.cn
mode http
optionforwardfor
balance source
cookie SERVERID
optionhttpchk HEAD /
server server1 192.168.1.101:80 cookie server1 check inter 2000 rise 3 fall 3 weight 3
server server2 192.168.1.102:80 cookie server2 check inter 2000 rise 3 fall 3 weight 3
server server3 192.168.1.103:80 cookie server3 check inter 2000 rise 3 fall 3 weight 3
#HAProxy管理页面
listen admin_stat
bind *:1158 #管理页面端口
mode http
stats refresh 10s #自动刷新时间
stats uri /haproxy #页面名称
stats realm Haproxy\ Statistics #登录提示
stats auth admin:admin #帐号密码
stats hide-version
stats admin if TRUE
保存退出
启动haproxy
sudo /usr/sbin/haproxy –f / /etc/haproxy/haproxy.cfg
修改
sudo vim /etc/default/haproxy
把ENABLED=0改成ENABLED=1
就能使用脚本启动
sudo /etc/init.d/haproxy start
四、配置keepalived
主keepalived
sudo vim /etc/keepalived/keepalived.conf
输入下列内容
! Configuration File for keepalived
global_defs {
router_id haproxy
}
vrrp_script check_run {
script "killall -0 haproxy"
interval 5
}
vrrp_sync_group VG1 {
group {
VI_1
}
}
vrrp_instance VI_1 {
state MASTER
interface eth0
virtual_router_id 51
priority 100
advert_int 1
authentication {
auth_type PASS
auth_pass haproxy
}
track_script {
check_run
}
virtual_ipaddress {
192.168.1.100
}
}
保存退出
备keepalived
sudo vim /etc/keepalived/keepalived.conf
加入下列内容
! Configuration File for keepalived
global_defs {
router_haproxy
}
vrrp_script check_run {
script "killall -0 haproxy"
interval 5
}
vrrp_sync_group VG1 {
group {
VI_1
}
}
vrrp_instance VI_1 {
state BACKUP
interface eth0
virtual_router_id 51
priority 50
advert_int 1
authentication {
auth_type PASS
auth_pass haproxy
}
track_script {
check_run
}
virtual_ipaddress {
192.168.1.100
}
}
保存退出
启动keepalived
sudo /etc/init.d/keepalived start
查看IP绑定情况
ip add
五、测试
测试省略
