Debian 源安装 NGINX+PHP+MYSQL

之前在Linode上一直用LNMP的一键安装包,这次改用阿里云,试下通过源安装LEMP环境,记录下安装过程。(VPS安全设置记录)

创建screen会话,执行

1
screen -S lemp

如果screen命令不存在,执行

1
apt-get install screen

如果网络掉线,重新连接,执行

1
screen -r lemp

修改源文件
在原有源的基础上加入新的源

1
vi /etc/apt/sources.list

在文件底部加入如下内容:

1
2
deb http://packages.dotdeb.org squeeze all
deb-src http://packages.dotdeb.org squeeze all

增加新加源的证书

1
2
wget http://www.dotdeb.org/dotdeb.gpg
cat dotdeb.gpg | apt-key add -

删除不用组件

1
apt-get --purge -y remove apache2-* bind9-* xinetd samba-*

更新源数据

1
2
apt-get update
apt-get upgrade

sed -i 's/max_execution_time = 30/max_execution_time = 300/g' /etc/php5/cgi/php.ini

启动PHP

1
/usr/bin/spawn-fcgi -a 127.0.0.1 -p 9000 -C 6 -u www-data -g www-data -f /usr/bin/php5-cgi

测试PHP
vi /home/www/default/p.php

1
<?php phpinfo(); ?>

安装MySQL

1
apt-get install mysql-server php5-mysql

安全设置

1
mysql_secure_installation

如果要重设密码,执行

1
dpkg-reconfigure mysql-server-5.0

重启PHP

1
2
killall -9 php5-cgi
/usr/bin/spawn-fcgi -a 127.0.0.1 -p 9000 -C 6 -u www-data -g www-data -f /usr/bin/php5-cgi

安装phpmyadmin

1
apt-get install phpmyadmin

注意会提示你选择Apache或者lighttpd服务器,我们用的是Nginx,所以这里按Esc退出选择,然后会提示你输入一次mysql数据库密码,两次phpmyadmin密码

安装完成后,phpmyadmin所有代码文件都默认位于/usr/share/phpmyadmin路径下,假设我们的Web主路径位于/home/www/default/phpmyadmin下,接下来做个链接就可以了:

1
ln -s /usr/share/phpmyadmin /home/www/default/phpmyadmin
