lnmp安装--php安装
版本：php5.6.4 x86_64
centos 6.6 x86_64
安装php之所以难，是因为要安装的扩展多，依赖关系复杂。
安装前的准备：
先看你想要安装哪些扩展。需要哪些包。下载地址：http://pan.baidu.com/s/1kTn7VQB

再看看配置项：
./configure --prefix=/usr/local/php --with-config-file-path=/etc --with-zlib --with-bz2 --with-freetype-dir --enable-mbstring --with-mysql=/usr/local/mysql/ --with-gd --with-libxml-dir --with-png-dir --with-jpeg-dir=/usr/local/jpeg --enable-sockets --enable-gd-native-ttf --with-curl=/usr/local/curl --enable-bcmath --with-mcrypt --enable-fpm --with-mysql --with-iconv --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd
可以看出我需要的功能有，gd库,mysql,mysqli,pdo,fpm,curl,mbstring。
可能新手会很困惑，php怎么和mysql结合，这里要说一下，php只需要安装上mysql的扩展（mysql,mysqli,pdo-mysql），php程序连接mysql的时候，会自动到对应host的端口连接mysql，只要mysql服务在监听就没有问题。
/etc/my.cnf配置
[mysqld] datadir=/var/lib/mysql socket=/var/lib/mysql/mysql.sock user=mysql # Disabling symbolic-links is recommended to prevent assorted security risks symbolic-links=0 [mysqld_safe] log-error=/var/log/mysqld.log pid-file=/var/run/mysqld/mysqld.pid [client] socket=/var/lib/mysql/mysql.sock
将上面所列出的包，依次安装上。
然后再./configure php
yum install libxml2 libxml2-devel yum install bzip2 bzip2-devel 找不到 gd.h。 gdlib-config --all 实际上找不到gd.h是因为没有安装下面两个包。 yum install libXpm yum install libXpm-devel 安装完，配置gd库。 perl ./Makefile.PL cd libgd-2.1.0-rc2 ./configure --with-xpm=/usr/lib 中间会显示gd支持的特性。 make make install cd GD-2.44 perl ./Makefile.PL make&&make install
./configure --prefix=/usr/local/php --with-config-file-path=/etc --with-zlib --with-bz2 --with-freetype-dir --enable-mbstring --with-mysql=/usr/local/mysql/ --with-gd --with-libxml-dir --with-png-dir --with-jpeg-dir=/usr/local/jpeg --enable-sockets --enable-gd-native-ttf --with-curl=/usr/local/curl --enable-bcmath --with-mcrypt --enable-fpm --with-mysql --with-iconv --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd
754 make 755 make install 756 php 757 /usr/local/sbin/php-fpm -h 758 /usr/local/php/sbin/php-fpm -h 759 ls /usr/local/php/php/ 760 ls /usr/local/php/ 761 ls 762 cp php.ini-development /usr/local/php/php/php.ini 763 ls /usr/local/php/php/ 764 find / -name php-fpm.conf.default 765 cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf 766 cp sapi/fpm/php-fpm /usr/local/bin/ 767 php-fpm start 768 php-fpm 769 vim /usr/local/php/php/php.ini
至此全部安装完毕。

可能发生的错误：
configure: error: Please reinstall the BZip2 distribution
yum install bzip2 bzip2-devel
yum install -y libmcrypt libmcrypt-devel
configure:error: *** libmcrypt was not found
为了的到mcrypt.so库文件，先后安装编译了mhash和libmcrypt, 但是到最后编译mcrypt时报错：
configure: error: *** libmcrypt was not found
[root@localhost] # export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH
再次编译

http://www.it165.net/os/html/201304/4868.html
安装gd的时候，会报这个错误 “usr/local/src/php-5.5.6/ext/gd/gd.c:57:22: error: X11/xpm.h: No such file or directory make: *** [ext/gd/gd.lo] Error 1”
yum install libXpm-dev libXpm
在配置gd2的时候多加一条 --with-xpm=/usr/lib
./configure 的时候 会发现
"Support for Xpm library : yes"这一项，说明配置成功。
php支持 mysqli，pdo-mysql
mysqlnd（专门为php写的），libmysqlclient（用c连接数据库用的，搞到php上来了）
http://php.net/manual/en/ref.pdo-mysql.php
nginx 发生permission deny
去看看php-fpm的用户配置，nginx的用户配置
当连接数据库的时候，我遇到这个问题了。后来发现，写127.0.0.1就可以连接，写localhost就不可以连接。mysql版本是 5.6.
create user 'root'@'localhost'的时候也有问题。总之搞不懂。
有人说和selinux有关。
