Ubuntu Server 9.04下安装nginx+PHP+MySQL
笔记而已，供以后查阅，大部分的内容参照http://blog.s135.com/nginx_php_v5/和http://rashost.com/blog，省去了第三方的一些编译，个人来说特别不喜欢编译（除非没有办法），自己编译不会带来性能多大的提高，维护起来还比较麻烦，尤其是卸载升级的时候。
Ubuntu Server 9.04的安装是最干净的那种，除了openssh-server，openssh-client外别的没有安装。
安装完系统后，如果选的是中文的话，最好重新设置一下语言：
vi /etc/default/locale
LANG="en_US.UTF-8"
LANGUAGE="en_US:en"这样不会有一些乱码啊，菱形字的出现。
设置apt升级源：
vi /etc/apt/sources.list全部干掉，测试了两个速度比较好的源：

deb-src http://mirrors.163.com/Ubuntu/ jaunty-proposed main restricted universe multiverse
deb-src http://mirrors.163.com/Ubuntu/ jaunty-backports main restricted universe multiverse设置完源之后，执行：
apt-get update获得软件包信息，如果需要升级系统，还需要：
apt-get upgrade这个貌似比yum要复杂些，怀念yum update & yum install yum-fastestmirror
安装MySQL
直接来apt-get安装吧：
apt-get install mysql-server-5.1 mysql-client-5.1 –no-install-recommends记得加上–no-install-recommends，要不然连postfix都给你装了。
安装nginx
添加www用户和www用户组
/usr/sbin/groupadd www
/usr/sbin/useradd -g www www安装第三方包：
apt-get install gcc
apt-get install libpcre3-dev libssl-dev下载源码编译：
tar xzf nginx-0.8.14.tar.gz -C /usr/local/src
cd /usr/local/src/nginx-0.8.14/
./configure –user=www –group=www –with-http_stub_status_module –with-http_ssl_module
make && make install缺什么就apt-get安装，编辑nginx配置文件：vi /usr/local/nginx/conf/nginx.conf

}编辑fcgi.conf文件，让nginx支持PATH_INFO变量：

# PHP only, required if PHP was built with –enable-force-cgi-redirect

下载最新的PHP5.2.10、php-fpm：
wget http://cn.php.net/get/php-5.2.10.tar.gz/from/this/mirror
wget http://php-fpm.org/downloads/php-5.2.10-fpm-0.5.13.diff.gz安装一些要用到的第三包：
apt-get install libxml2-dev libmcrypt-dev libssl-dev libldap2-dev libmhash-dev libmysqlclient-dev libcurl4-openssl-dev libpng-dev libjpeg-dev libsasl2-dev libdb4.7-dev解压缩PHP源码，并打上php-fpm补丁：
tar xzf php-5.2.10.tar.gz -C /usr/local/src
gzip -cd php-5.2.10-fpm-0.5.11.diff.gz patch -d /usr/local/srcphp-5.2.10 -p1编译安装PHP&php-fpm：
./configure –with-iconv –with-zlib –enable-xml –disable-rpath –enable-discard-path –enable-bcmath –enable-shmop –enable-sysvsem –enable-inline-optimization –with-curl –with-curlwrappers –enable-mbregex –enable-fastcgi –enable-fpm –enable-force-cgi-redirect –enable-mbstring –with-mcrypt –with-gd –enable-gd-native-ttf –with-mhash –enable-pcntl –enable-sockets –with-xmlrpc –enable-zip –with-mysql –with-mysqli –enable-sqlite-utf8 –with-pdo-mysql –enable-ftp –with-jpeg-dir –with-png-dir –enable-dba –with-db4=/usr/lib/ –without-pear
make
make install可以看到我在扩展里面打开了dba扩展，并且指定了bdb库位置，如果你不需要PHP去访问bdb可以不用。安装的过程中提示缺什么包，直接apt-get install就可以了，也没有必要担心安装的不全，到时候缺什么，直接单个编译就可以了，比如想编译APC支持，到APC源码位置：
phpize
./configure
make
make install如果没有安装autoconf包，直接apt-get install autoconf就可以。把编译好的so文件拷贝到php扩展目录就可以了。
复制php.ini-recommended为php.ini到php ini配置目录，目录可以通过php -i|grep php.ini查看。找到php-fpm.con(命令：whereis php-fpm.conf)，去掉display_errors参数的注释，修改参数值为1；去掉user,group参数的注释，设置user，group，一般设定为www就可以；修改max_children参数的值。
启动服务器
ulimit -SHn 51200
/usr/local/sbin/php-fpm start
/usr/local/nginx/sbin/nginx测试
最基础的测试，phpinfo.php：
测试了下ColaPHP在nginx+php+fastcgi下的表现，原生的PHP大概940RPS，ColaPHP大概是650RPS。
