(1)在app动态服务器快速搭建LAMP环境:
yum install -y httpd mysql-server php php-mysql
(2)创建discuz论坛的mysql用户:
MySQL [(none)]> GRANT ALL ON *.* TO 'nihao'@'localhost' IDENTIFIED BY '123456';
MySQL [(none)]> FLUSH PRIVILEGES;
(7)OK,接下来可以安装haproxy来进行设置acl调度了:
[root@localhost ~]# yum install -y haproxy
[root@localhost ~]# cat /etc/haproxy/haproxy.cfg

# 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
#

(10)修改HAproxy的配置文件,把静态资源的调度IP改为varnish:
[root@localhost ~]# cat /etc/haproxy/haproxy.cfg
#---------------------------------------------------------------------
# Example configuration for a possible web application. See the
# full configuration options online.
#
# http://haproxy.1wt.eu/download/1.4/doc/configuration.txt

OK,haproxy+varnish实现动静资源分离和静态资源的缓存到此暂告一段落,更多内容请关注我的博客。
