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

  758  /usr/local/php/sbin/php-fpm -h

  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.linuxidc.com/Linux/2009-03/18739.htm

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。
