把最后yakjuly的移行的sh改成bash 即可

sh 和 bash 是两个不同的shell，linux下有很多种shell。
sh比较小，但是功能没有bash多，bash用得比较普遍

通常这是由于$HOME，$HOME/.ssh的文件权限造成的，或者是$HOME/.ssh/authorized_keys的权限超过了sshd默认允许的权限。

如果是这样，可以执行下面的命令去解决这个问题：

$ chmod go-w $HOME $HOME/.ssh
$ chmod 600 $HOME/.ssh/authorized_keys

昨天把主机从dreamhost换到了linode，虽然觉得dreamhost很不错 但是没有root权限始终有点不快。

今年打算把服务器，运维等知识好好补充一下，于是买了口碑一直不错的linode的VPS。

第一天的任务就是 迁移博客。

1. scp把wordpress文件 都拷贝至新主机上

2.apt-get 安装mysql php5 php5-mysql php5-cgi libfcgi-dev spawn-fcgi nginx

3.使用spawn-fcgi 脚本 启动php5-cgi进程

sudo spawn-fcgi -f /usr/bin/php5-cgi -a 127.0.0.1 -p 9000 -C 3 -P /var/run/php5-cgi.pid

4.配置nginx

在/etc/nginx/sites-enabled下创建 yakjuly.com文件

server {
        listen   80;
        server_name yakjuly.com;

        access_log  /home/yakjuly/applications/yakjuly.com/log/access.log;
        error_log /home/yakjuly/applications/yakjuly.com/log/error.log;
        rewrite /wp-admin$ $scheme://$host$uri/ permanent;

        location / {
                root   /home/yakjuly/applications/yakjuly.com;
                index  index.php index.html index.htm;

                if (-f $request_filename/index.html){
                        rewrite (.*) $1/index.html break;
                }
                if (-f $request_filename/index.php){
                        rewrite (.*) $1/index.php;
                }
                if (!-e $request_filename){
                         rewrite . /index.php;
                }
        }

        location ~ .*\.php$ {
                include /etc/nginx/fastcgi_params;
                fastcgi_pass 127.0.0.1:9000;
                fastcgi_index index.php;
                fastcgi_param   SCRIPT_FILENAME /home/yakjuly/applications/yakjuly.com$fastcgi_script_name;
        }
}

rewrite /wp-admin$ $scheme://$host$uri/ permanent;
