迁移代码
将源代码scp至新的server上
搭建服务
yum安装nginx服务
yum install nginx #yum安装
service nginx start #启动服务
配置文件相关
备份原文件
cp /etc/nginx/nginx.conf /etc/nginx/nginx.conf.bak
因为我是同时迁移两个不通域名的web后台，所以涉及到了nginx的虚拟目录
为了主配置文件清晰点，所以使用了 include /etc/nginx/conf.d/*.conf; 将不通的server配置拆分出去~
include 要写在http字段内(#废话#)
vi /etc/nginx/nginx.conf

虚拟目录配置
到/etc/nginx/conf.d/ 下创建以.conf结尾的文件会被nginx解析 aaa.com.conf bbb.com.conf
[root@]# cd /etc/nginx/conf.d/ [root@]# ll total 12 -rw-r--r-- 1 root root 516 Jul 24 13:54 aaa.com.conf -rw-r--r-- 1 root root 556 Jul 28 16:59 bbb.conf [root@]#
[root@iz8vbilqy0q9v8tds55bqzz conf.d]# cat aaa.com.conf
server {
listen 80;
server_name aaa.com;
root /var/www/aaa.com;
index index.html index.htm index.php;
location /APP/{ #例如nginx的重定向功能，将访问/APP/开头指定到interface文件中
index index.php;
if (!-e $request_filename){
rewrite ^/APP/(.*)$ /interface.php?s=$1 last;
break;
}
}
location ~ .php$ { #指定本地php解析，fastcgi 信息
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
#fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param SCRIPT_FILENAME /var/www/aaa.com$fastcgi_script_name;
include fastcgi_params;
}
}
[root@]#
[root@iz8vbilqy0q9v8tds55bqzz conf.d]# cat bbb.com.conf
server {
listen 80;
server_name bbb.com;
root /var/www/bbb.com;
index index.html index.htm index.php;
location /APP/{ #例如nginx的重定向功能，将访问/APP/开头指定到interface文件中
index index.php;
if (!-e $request_filename){
rewrite ^/APP/(.*)$ /interface.php?s=$1 last;
break;
}
}
location ~ .php$ { #指定本地php解析，fastcgi 信息
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
#fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param SCRIPT_FILENAME /var/www/bbb.com$fastcgi_script_name;
include fastcgi_params;
}
}
[root@]#
按以上配置完成后，即可访问相应的目录~
www.aaa.com
www.bbb.com
##########################################################
有个小插曲记录一下，我搭建好服务后发现bbb.com的php文件没有解析，aaa却正常，报错~
原来两个服务的框架不一样，bbb的框架写的不太规范，导致了解析失败，更改php.ini文件解决
short_open_tag = Off 默认为OFF更改为 short_open_tag = ON
官方的解释，是要打开适配 <? ?> 这种不规则的写法。~~~~
; This directive determines whether or not PHP will recognize code between ; <? and ?> tags as PHP source which should be processed as such. It's been ; recommended for several years that you not use the short tag "short cut" and ; instead to use the full <?php and ?> tag combination. With the wide spread use ; of XML and use of these tags by other languages, the server can become easily ; confused and end up parsing the wrong code in the wrong context. But because ; this short cut has been a feature for such a long time, it's currently still ; supported for backwards compatibility, but we recommend you don't use them. ; Default Value: On ; Development Value: Off ; Production Value: Off ; http://php.net/short-open-tag short_open_tag = ON

还有类似的权限啊，chown -R nginx.nginx /var/www/xxxx 等等细节需要注意，有可能会影响~
#######################
如果有redis服务的话，也会影响使用，例如缺少了redis的插件，redis服务没有集体迁移
我就遇到了redis服务迁移出的问题，redis内容太大了我内存比较低导致了服务总被系统kill掉，通过dmesg日志才发现的。。。

迁移的时候问题很多，查看nginx和php的错误日志可以很快定位问题
