2.haproxy的配置

    1.基础配置文件

    [root@node04 haproxy]# pwd
    /etc/haproxy
    [root@node04 haproxy]# vim haproxy.cfg 
    global
    maxconn 100000
    chroot /usr/local/haproxy
    #stats socket /var/lib/haproxy/haproxy.sock mode 600 level admin
    uid 99
    gid 99
    daemon
    nbproc 2
    cpu-map 1 0    haproxy第一个进程绑定到第0个CPU上
    cpu-map 2 1   haproxy第二个进程绑定到第1个CPU上
    #cpu-map 3 2
    #cpu-map 4 3
    pidfile /usr/local/haproxy/run/haproxy.pid
    log 127.0.0.1 local3 info
    
    defaults
    option http-keep-alive
    option  forwardfor
    maxconn 100000
    mode http
    timeout connect 300000ms
    timeout client  300000ms
    timeout server  300000ms
    
    listen stats
     mode http
     bind 0.0.0.0:9999
     stats enable
     log global
     stats uri     /haproxy-status
     stats auth    haadmin:q1w2e3r4ys
    
    listen  web_port
     bind 0.0.0.0:80
     mode http
     log global
     server web1  127.0.0.1:8080  check inter 3000 fall 2 rise 5
    

    2.独立的haproxy日志配置

    [root@node04 haproxy-1.8.20]# vim /etc/rsyslog.conf
    # Save boot messages also to boot.log
    local7.*                                                /var/log/boot.log
    local3.*                                                /var/log/haproxy_linux43.log
    $ModLoad imudp
    $UDPServerRun 514
    
    [root@node04 haproxy-1.8.20]# ll /var/log/ha*
    ls: cannot access /var/log/ha*: No such file or directory
    [root@node04 haproxy-1.8.20]# systemctl restart rsyslog
    [root@node04 haproxy-1.8.20]# ll /var/log/ha*
    ls: cannot access /var/log/ha*: No such file or directory
    [root@node04 haproxy-1.8.20]# systemctl restart haproxy
    [root@node04 haproxy-1.8.20]# systemctl restart rsyslog
    [root@node04 haproxy-1.8.20]# ll /var/log/ha*
    -rw-------. 1 root root 129 Jul 15 01:22 /var/log/haproxy_linux43.log
    
    
    listen web
     mode tcp
     bind 192.168.177.154:80,192.168.177.154:81  两个地址,一个外部防火墙调用,一个内部使用,可以使用不同IP地址,走不同网卡,走eth0和eth1,不会把流量压在一个网卡上
     server web1 192.168.177.155:80
     server web2 192.168.177.156:80
    

    标准错误示范

    一定要写具体的IP地址加端口
    frontend web
     bind *:80
     use_backend web_host
    
    backend web_host
     server web1 192.168.177.155:80
     #server web2 192.168.177.156:80
    
    listen web
     mode tcp
     bind 192.168.177.154:80,192.168.177.154:81
     #server web1 192.168.177.155:80
     server web2 192.168.177.156:80
    

    官方配置文件

    #官网业务访问入口======================================
    frontend WEB_PORT_80
     bind 192.168.7.248:80
     mode tcp
     use_backend web_prot_http_nodes
    
    backend web_prot_http_nodes
     mode tcp
     option forwardfor
     server 192.168.7.101 192.168.7.101:80 check inter 3000 fall 3 rise 5
     server 192.168.7.102 192.168.7.102:80 check inter 3000 fall 3 rise 5
    
    
    #官网业务访问入口======================================
    frontend WEB_PORT_443
     bind 192.168.7.248:443
     mode tcp
     use_backend web_prot_https_nodes
    
    backend web_prot_https_nodes
     mode tcp
     option forwardfor
     server 192.168.7.101 192.168.7.101:443 check inter 3000 fall 3 rise 5
     server 192.168.7.102 192.168.7.102:443 check inter 3000 fall 3 rise 5
    
    使用listen替换frontend和backend的配置方式:
    #官网业务访问入口=====================================
    listen WEB_PORT_80
    bind 192.168.7.102:80
    mode http
    option forwardfor
    server web1 192.168.7.101:8080 check inter 3000 fall 3 rise 5
    server web2 192.168.7.101:8080 check inter 3000 fall 3 rise 5
    
    程序环境:
    主程序: /usr/sbin/haproxy
    配置文件: /etc/haproxy/haproxy.cfg
    Unit file: /usr/lib/systemd/system/haproxy.service
    
    配置段:
    • global:全局配置段
    进程及安全配置相关的参数
    性能调整相关参数
    Debug参数
    • proxies:代理配置段
    defaults:为frontend, backend, listen提供默认配置
    frontend:前端,相当于nginx中的server {}
    backend:后端,相当于nginx中的upstream {}
    listen:同时拥有前端和后端配置::
