题外话：由于近段时间测试环境ssh链路质量不大好，经常短线。故我把整个安装过程放到screen里去执行，以防止断线中断了安装过程。执行screen -S install，这样断线后，只要再执行screen -r install 就可以恢复之前的安装界面。

1.安装mysql

sudo apt-get install mysql-server mysql-client
安装过程中要设置mysql root用户的密码。

2.安装nginx

sudo apt-get install nginx

3.安装成功后。我们重启下nginx服务

sudo service nginx restart
启动之后我们就可以访问一下我们的地址了。看能不能出现nginx的欢迎界面。

4.安装php5-fpm(PHP5 - FastCGI Process Manager)。

sudo apt-get install php5-fpm

5.接下来我们要修改一下nginx的站点配置了。

ngnix的配置文件存放在/etc/nginx/sites-available/default

server {
listen 80; ## listen for ipv4; this line is default and implied
listen [::]:80 default ipv6only=on; ## listen for ipv6
root /usr/share/nginx/www;
index index.php index.html index.htm;
# Make site accessible from http://localhost/
server_name _;
location / {
# First attempt to serve request as file, then
# as directory, then fall back to index.html
try_files $uri $uri/ /index.html;
}
location /doc {
root /usr/share;
autoindex on;
allow 127.0.0.1;
deny all;
}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/www;
}
# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
#location ~ \.php$ {
# proxy_pass http://127.0.0.1;
#}
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
location ~ \.php$ {
try_files $uri =404;
#fastcgi_pass 127.0.0.1:9000;
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_index index.php;
include fastcgi_params;
}
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
location ~ /\.ht {
deny all;
}
}
增加了php解析的一些代码在里面。

6.我们在安装php5相关的一些组件。

sudo apt-cache search php5
apt-get install php5-mysql php5-curl php5-gd php5-intl php-pear php5-imagick php5-imap php5-mcrypt php5-memcache php5-ming php5-ps php5-pspell php5-recode php5-snmp php5-sqlite php5-tidy php5-xmlrpc php5-xsl
7.重启服务

sudo service php5-fpm restart
sudo service nginx
8.写个探针文件试试吧。呵呵。
