    centos7配置haproxy
    b. 外网配置:
    cat /etc/sysconfig/network-scripts/ifcfg-eth1
    centos7配置haproxy
    c. 安装:
    yum -y install haproxy

    listen haproxy3-monitoring *:80                # Haproxy Monitoring 的使用端口:80
    mode http
    option forwardfor
    option httpclose
    stats enable
    stats show-legends
    stats refresh 5s
    stats uri /stats                            
    stats realm Haproxy\ Statistics
    stats auth testuser:test1234               
    stats admin if TRUE
    default_backend app-main
    frontend main
    bind *:80
    option http-server-close
    option forwardfor
    default_backend app-main
    backend app-main
    balance roundrobin

    server server2 192.168.8.84:80 check

    f. 配置rsyslog:
    vim /etc/rsyslog.conf,去掉如下行的注释:
    centos7配置haproxy
    g. 创建rsyslog的haproxy配置文件:
    vim /etc/rsyslog.d/haproxy.conf,写入如下内容:

    local2.=info     /var/log/haproxy-access.log    # 访问日志
    local2.notice    /var/log/haproxy-info.log      # haproxy执行信息

    h. 重启rsyslog:
    systemctl restart rsyslog
    i. 启动haproxy:
    systemctl start haproxy
    j. 关闭apache:
    systemctl stop httpd

  3. web1服务器配置:
    a. 内网配置:
    cat /etc/sysconfig/network-scripts/ifcfg-eth0
    centos7配置haproxy
    b. 关闭防火墙:
