    # to have these messages end up in /var/log/haproxy.log you will
    # need to:
    #
    # 1) configure syslog to accept network log events.  This is done
    #    by adding the '-r' option to the SYSLOGD_OPTIONS in
    #    /etc/sysconfig/syslog
    #
    # 2) configure local2 events to go to the /var/log/haproxy.log
    #   file. A line like the following can be added to
    #   /etc/sysconfig/syslog
    #
    #    local2.*                       /var/log/haproxy.log
    #
    log         127.0.0.1 local2

sudo service haproxy restart

【在CentOS下安装apache】

CentOS的软件管理程序是yum

首先还是安装Apache。

sudo yum install httpd

与openSUSE类似，安装完需要自己手动配置服务自启动。

sudo chkconfig --levels 235 httpd on

然后立即启动Apache服务。

sudo /etc/init.d/httpd start

现在再用浏览器访问服务器地址就可以正常访问Http服务器了。
