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  
   option  httplog            #http 日志格式 
   option  httpclose          #主动关闭http通道 
   option  redispatch         #强制定向到其他健康的服务器 
   option  forwardfor 
   option  dontlognull 
   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
frontend  web             #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
        option  forwardfor
        balance source
        cookie SERVERID
        option  httpchk 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
