1.环境
centos5.8 64bit
varnish 3.0.2


2.centos varnish安装 略



3.varnish 503解决方法: 
vi /etc/sysconfig/varnish
#在DAEMON_OPTS=里面下面参数
-p http_resp_hdr_len=8192

修改配置文件 
vi /etc/varnish/default.vcl
backend default {
    .host = "119.147.147.147";
    .port = "88";
    .connect_timeout = 8s;

ubuntu下单网卡多vlan配置，简单实用。


1.安装vlan 
sudo apt-get install vlan


2.加载模块 
echo 8021q >> /etc/modules
modprobe -a 8021q



3.修改配置 
vi /etc/network/interfaces
auto eth1.5
iface eth1.5 inet static
address 119.156.156.156
netmask 255.255.255.0
gateway 119.147.156.1
vlan-raw-device eth1

auto eth1.4001
iface eth1.4001 inet static
address 58.253.253.253
netmask 255.255.255.0
vlan-raw-device eth1

参考: https://wiki.ubuntu.com/vlan


4.交换机上配置端口，允许vlan5,4001通过


5.配置原路返回路由
参考 linux双线/多线机器路由配置

原因和解决办法：
这个界面只会出现在PHP进程不是以用户身份来运行的主机上，也就是你的服务器运行PHP的用户和WP文件夹的所有者不一样，
目的就是为了安全，wordpress在升级时会创建一个

临时文件看看owner是不是和当前运行的php是否一样，如果不一样，就会出现这个界面。

 

遇到这种情况有两种解决办法，第一种就是填写连接信息，如果你为了以后更新方便的话可以在 wp-config.php 中加入一下代码：(注意下面代码单引号换成英文状态的)

// ** FTP SETTINGS FOR AUTO-UPDATE ** //
define('FTP_HOST', ‘localhost’);
define('FTP_USER', ‘ftpuser’);
define('FTP_PASS', ‘ftppass’);

这样无论你升级 wordpress 或者插件的时候就都不会有那个提示了。

 

还有一个办法，那就是修改文件的权限和用户组，既然我们已经知道了出现这个提示的原因，当然我们就有了解决的办法，
首先修改Wordpress 的权限，需要有写的权限：
chmod -R 755 /var/www/wordpress
解释：chmod是修改文件(夹)权限的命令，这里加了一个R参数，就是把/var/www/wordpress文件夹内的所有文件(夹)的权限都修改为755
chown -R www /var/www/wordpress
解释： chown是修改文件(夹)用户组的命令，参数R的作用和 chmod 的一样，不过执行此命令需要有root权限。
这样假设你的PHP的用户组是www，修改完以后再去尝试WP的自动升级，一键升级就能顺利进行了。

win7共享 所有网段访问

这个问题很郁闷，网上找了好多资料都不能解决，自己研究了一下，所有问题均出在win7防火墙。

 

在单位的电脑安装WIN7系统，IP是192.168.20.0网段，而公司有些电脑使用的是60网段IP,在我的电脑上面共享时，本网段内的电脑可以访问，但60网段的电话确不能访问。

 

如果有遇到同样问题的，可以导入下面这个win7防火墙配置，测试过，可以跨网段访问win7共享。只需要在防火入站规则里面添加4个端口通过，udp 137,138，tcp 139,445，然后重启下系统。
