    #使用uname -r查看内核，如：2.6.18-371.el5，此时该参数就为linux26
    #kernel 大于2.6.28的用：TARGET=linux2628
    PREFIX=/usr/local/haprpxy   #/usr/local/haprpxy为haprpxy安装路径

     2.配置启动脚本

    1
    2
     3
    cp /usr/local/src/haproxy-1.6.3/examples/haproxy.init /etc/init.d/haproxy
    chmod +x /etc/init.d/haproxy
    useradd -r haproxy -s /sbin/nologin

    如果是ubuntu系统需要/etc/init.d/functions为/lib/lsb/init-functins

    注释/etc/sysconfig/network   [ ${NETWORKING} = "no" ] && exit 0

    同时去除start 里面damon

     3.配置环境变量

    1
    2
    echo 'PATH="/usr/local/haproxy/sbin:$PATH"' >> /etc/profile
    source /etc/profile

     4.haproxy配置文件

    1
    2
    3
    4
    mkdir /etc/haproxy
    mkdir /var/lib/haproxy
    cd /etc/haproxy/
    vim haproxy.cfg

     5.启动脚本更改

    1
    2
    vim /etc/init.d/haproxy
     35 BIN=/usr/sbin/$BASENAME   # 替换BIN=/usr/local/haproxy/sbin/$BASENAME

     6.配置haproxy日志

    7
    [root@localhost haproxy-1.6.3]# vim /etc/rsyslog.conf     #17,18是关于tcp行注释取消，#最后增加一行
     16 # Provides TCP syslog reception
     17 $ModLoad imtcp
     18 $InputTCPServerRun 514
      
    local3.* /var/log/haproxy.log
    [root@localhost haproxy-1.6.3]# /etc/init.d/rsyslog restart
