# 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

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。
