1.源码部署haproxy

//安装编译环境 [root@LB ~]# yum -y install make gcc pcre-devel bzip2-devel openssl-devel systemd-devel --allowerasing  //创建haproxy用户 [root@LB ~]# useradd -r -M -s /sbin/nologin haproxy  //下载,解压和安装 [root@LB ~]# wget https://src.fedoraproject.org/repo/pkgs/haproxy/haproxy-2.1.3.tar.gz/sha512/4728c1177b2bba69465cbc56b1ed73a1b2d36891ba2d94d29bb49714ad98ccfac4b52947735aded211f0cd8070002f5406ddd77cabd2f8230b00438189dd7a60/haproxy-2.1.3.tar.gz [root@LB ~]# tar -xzf haproxy-2.1.3.tar.gz  [root@LB ~]# cd haproxy-2.1.3 [root@LB haproxy-2.1.3]# make clean [root@LB haproxy-2.1.3]# make -j $(grep 'processor' /proc/cpuinfo |wc -l)   > TARGET=linux-glibc   > USE_OPENSSL=1   > USE_ZLIB=1   > USE_PCRE=1   > USE_SYSTEMD=1 [root@LB haproxy-2.1.3]# make install PREFIX=/usr/local/haproxy [root@LB haproxy-2.1.3]# cp haproxy  /usr/sbin/  //设置Linux内核参数 [root@LB haproxy-2.1.3]# vim /etc/sysctl.conf net.ipv4.ip_forward = 1 net.ipv4.ip_nonlocal_bind = 1 [root@LB haproxy-2.1.3]# sysctl -p net.ipv4.ip_forward = 1 net.ipv4.ip_nonlocal_bind = 1  //配置haproxy服务 [root@LB haproxy-2.1.3]# mkdir /etc/haproxy [root@LB haproxy-2.1.3]# vim /etc/haproxy/haproxy.cfg global     log 127.0.0.1 local0  info     #log loghost local0 info     maxconn 20480 #chroot /usr/local/haproxy     pidfile /var/run/haproxy.pid     #maxconn 4000     user haproxy     group haproxy     daemon #--------------------------------------------------------------------- #common defaults that all the 'listen' and 'backend' sections will #use if not designated in their block #--------------------------------------------------------------------- defaults     mode http     log global     option dontlognull     option httpclose     option httplog     #option forwardfor     option redispatch     balance roundrobin     timeout connect 10s     timeout client 10s     timeout server 10s     timeout check 10s     maxconn 60000     retries 3 #--------------统计页面配置------------------ listen admin_stats     bind 0.0.0.0:8189     stats enable     mode http     log global     stats uri /haproxy_stats     stats realm Haproxy Statistics     stats auth admin:admin     #stats hide-version     stats admin if TRUE     stats refresh 30s #---------------web设置----------------------- listen webcluster     bind 0.0.0.0:80     mode http     #option httpchk GET /index.html     log global     maxconn 3000     balance roundrobin     cookie SESSION_COOKIE insert indirect nocache     server web01 192.168.111.142:80 check inter 2000 fall 5     #server web01 192.168.111.143:80 cookie web01 check inter 2000 fall 5  //启动haproxy,配置haproxy.service服务单元文件 [root@LB ~]# vim /usr/lib/systemd/system/haproxy.service [Unit] Description=HAProxy Load Balancer After=syslog.target network.target  [Service] ExecStartPre=/usr/local/haproxy/sbin/haproxy -f /etc/haproxy/haproxy.cfg   -c -q ExecStart=/usr/local/haproxy/sbin/haproxy -Ws -f /etc/haproxy/haproxy.cfg  -p /var/run/haproxy.pid ExecReload=/bin/kill -USR2 $MAINPID  [Install] WantedBy=multi-user.target [root@LB ~]# systemctl daemon-reload  //配置日志信息 [root@LB ~]# vim /etc/rsyslog.conf local0.*        /var/log/haproxy.log [root@LB ~]# systemctl enable --now rsyslog [root@LB ~]# systemctl restart rsyslog [root@LB ~]# systemctl enable --now haproxy [root@LB ~]# systemctl restart haproxy  

2.Haproxy搭建http负载均衡

//LB、RS1、RS2都关闭防火墙和selinux //RS1和RS2部署httpd #RS1 [root@RS1 ~]# yum -y install httpd [root@RS1 ~]# echo RS1 > /var/www/html/index.html [root@RS1 ~]# systemctl enable --now httpd #RS2 [root@RS2 ~]# yum -y install httpd [root@RS2 ~]# echo RS2 > /var/www/html/index.html [root@RS2 ~]# systemctl enable --now httpd 
//修改LB的内核参数 [root@LB ~]# vim /etc/sysctl.conf net.ipv4.ip_nonlocal_bind = 1 net.ipv4.ip_forward = 1 [root@LB ~]# sysctl -p net.ipv4.ip_nonlocal_bind = 1 net.ipv4.ip_forward = 1  //修改haproxy配置文件 [root@LB ~]# vim /etc/haproxy/haproxy.cfg global     daemon     maxconn 256      defaults     mode http     timeout connect 5000ms     timeout client 50000ms     timeout server 50000ms  frontend http-in     bind *:80     default_backend servers  backend servers     server web01 192.168.111.142:80     server web02 192.168.111.143:80      [root@LB ~]# systemctl restart haproxy  //客户端验证 [root@client ~]# curl http://192.168.111.141 RS1 [root@client ~]# curl http://192.168.111.141 RS2 [root@client ~]# curl http://192.168.111.141 RS1 [root@client ~]# curl http://192.168.111.141 RS2  //使用WEB网页访问测试 [root@LB ~]# vim /etc/haproxy/haproxy.cfg global     log 127.0.0.1 local0  info     #log loghost local0 info     maxconn 256 #chroot /usr/local/haproxy     pidfile /var/run/haproxy.pid     #maxconn 4000     user haproxy     group haproxy     daemon #--------------------------------------------------------------------- #common defaults that all the 'listen' and 'backend' sections will #use if not designated in their block #--------------------------------------------------------------------- defaults     mode http     log global     option dontlognull     option httpclose     option httplog     #option forwardfor     option redispatch     balance roundrobin     timeout connect 5000ms     timeout client 50000ms     timeout server 50000ms     timeout check 10s     maxconn 60000     retries 3 #--------------统计页面配置------------------ listen admin_stats     bind 0.0.0.0:8189     stats enable     mode http     log global     stats uri /haproxy_stats     stats realm Haproxy Statistics     stats auth admin:admin     #stats hide-version     stats admin if TRUE     stats refresh 30s #---------------web设置----------------------- listen webcluster     bind 0.0.0.0:80     mode http     #option httpchk GET /index.html     log global     maxconn 3000     balance roundrobin     cookie SESSION_COOKIE insert indirect nocache     server web01 192.168.111.142:80 check inter 2000 fall 5     server web02 192.168.111.143:80 cookie web01 check inter 2000 fall 5 [root@LB ~]# systemctl restart haproxy [root@LB ~]# ss -anlt State            Recv-Q           Send-Q                       Local Address:Port                       Peer Address:Port           Process            LISTEN           0                128                                0.0.0.0:22                              0.0.0.0:*                                 LISTEN           0                128                                0.0.0.0:8189                            0.0.0.0:*                                 LISTEN           0                128                                0.0.0.0:80                              0.0.0.0:*                                 LISTEN           0                128                                   [::]:22                                 [::]:*
