需求背景：
服务器上，跑的lamp环境，上面有很多客户的项目，每个项目就是一个网站。 由于客户在不断增加，每次增加一个客户（自动创建密码），就需要配置相应的mysql、ftp以及httpd. 这种工作是重复性非常强的，所以用脚本实现非常合适。
mysql增加的是对应客户项目的数据库、用户、密码，ftp增加的是对应项目的用户、密码（使用vsftpd，虚拟用户模式），httpd就是要增加虚拟主机配置段。
首先需要一个基础的nginx虚拟主机配置文件， 一般情况下，我们配置虚拟主机都是建一个vhost目录， 这里我在 /usr/local/nginx/conf/vhost 下面建了一个dd.conf文件
代码语言：javascript复制server
{
listen 80;
server_name #host#;
index index.html index.htm index.php;
root /data/wwwroot/#host#;
##add php jiexi
location ~ .php$
{
include fastcgi_params;
fastcgi_pass unix:/tmp/#host#.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /data/wwwroot/#host#$fastcgi_script_name;
}
}绞尽脑汁也没有找出来如何能够添加一个新的虚拟机配置文件，在网上找到了灵感！（感谢度娘 1）
在 /usr/local/php-fpm/etc 下面建了一个pp.conf文件
代码语言：javascript复制[[email protected] etc]# cat pp.conf
[#php#]
listen = /tmp/#php#.sock
listen.mode = 666
user = php-fpm
group = php-fpm
pm = dynamic
pm.max_children = 50
pm.start_servers = 10
pm.min_spare_servers = 5
pm.max_spare_servers = 15
pm.max_requests = 50
rlimit_files = 1024在 /etc/vsftpd/vsftpd_user_conf/ 下面建了一个ftpuser文件
代码语言：javascript复制[[email protected] vsftpd_user_conf]# cat ftpuser
local_root=/home/ftpuser/#ftpuser#
anonymous_enable=NO
write_enable=YES
local_umask=022
anon_upload_enable=NO
anon_mkdir_write_enable=NO
idle_session_timeout=600
data_connection_timeout=120
max_clients=10注意里面一些关键路径，我用特殊字符组合来表示，这样方便我们添加虚拟注意的时候进行匹配替换。
lnmpvhost.sh 脚本如下：
一定要先满足如下条件：
代码语言：javascript复制关闭iptables 以及selinux
yum install -y expect#! /bin/bash
