买了一个bluevm年付15刀128M内存的小鸡鸡玩。发现装PHP MYSQL 等环境目前的安装包都有点难承受。

找了很多资料,发现LLSMP是一个很不错的选择,但安装完毕之后MYSQL也必须优化,不然128的内存还是一样会爆掉。

小内存的话,一般推荐Debian系统。听说这个系统要比其他系统剩点内存,真的假的我没测试。

由于LLSMP发布到0.6就熄火了,官方网站甚么都打不开了,那么我们就安装0.6吧

CentOS:
PHP5.2

wget http://llsmp.googlecode.com/files/llsmp0.6_centos.tar.gz tar zxvf llsmp0.6_centos.tar.gz cd centos sh install.sh

PHP5.3

wget http://llsmp.googlecode.com/files/llsmp0.6_centos.tar.gz tar zxvf llsmp0.6_centos.tar.gz cd centos sh install.sh php5.3

Debian:
PHP5.2

wget http://llsmp.googlecode.com/files/llsmp0.6_debian.tar.gz tar zxvf llsmp0.6_debian.tar.gz cd debian sh install.sh

PHP5.3

wget http://llsmp.googlecode.com/files/llsmp0.6_debian.tar.gz tar zxvf llsmp0.6_debian.tar.gz cd debian sh install.sh php5.3

Ubuntu:
PHP5.2

wget http://llsmp.googlecode.com/files/llsmp0.6_ubuntu.tar.gz tar zxvf llsmp0.6_ubuntu.tar.gz cd ubuntu sh install.sh

PHP5.3

wget http://llsmp.googlecode.com/files/llsmp0.6_ubuntu.tar.gz tar zxvf llsmp0.6_ubuntu.tar.gz cd ubuntu sh install.sh php5.3

根据自己的系统,安装上面的步骤,按照提示一步一步安装就OK了。

结束以后,128的内存还是有些抵不住MYSQL的占用,那么还需要优化MYSQL。

在/etc/mysql/下,找到my.cnf(注意备份)
按照我以下的修改。。。

# # The MySQL database server configuration file. # # You can copy this to one of: # - "/etc/mysql/my.cnf" to set global options, # - "~/.my.cnf" to set user-specific options. # # One can use all long options that the program supports. # Run program with --help to get a list of available options and with # --print-defaults to see which it would actually understand and use. # # For explanations see # http://dev.mysql.com/doc/mysql/en/server-system-variables.html # This will be passed to all mysql clients # It has been reported that passwords should be enclosed with ticks/quotes # escpecially if they contain "#" chars... # Remember to edit /etc/mysql/debian.cnf when changing the socket location.

结束后,重启一下。。。然后看看吧,内存占用没那么多了,装个WP也一样的正常了。

反正我是这么搞定128M的小鸡,如果有其他意见,欢迎拍砖~
