php安装配置  
  
1、lnmp下的php  
apache====》libphp5.so  
nginx php===》fcgi php-fpm port 9000  
  
2、php安装准备  
检查  
\[root@nginx db\]\# netstat -lntup | egrep "nginx|mysql"  
tcp        0      0 0.0.0.0:80                  0.0.0.0:\*                   LISTEN      51156/nginx           
tcp        0      0 0.0.0.0:3306                0.0.0.0:\*                   LISTEN      65163/mysqld   
\-------------------------------------------------------------  
yum install –y zlib libxml zlib-devel libjpeg freetype libpng gd curl libiconv libxml2-devel freetype-devel libpng-devel gd-devel curl-devel gcc glibc glibc-common  xinetd openssl-devel  ncurses-devel gcc-c++ wget tree vim lsof apr\*  
\-------------------------------------------------------------  
tar -zxvf libiconv-1.14.tar.gz   
cd libiconv-1.14  
./configure --prefix=/usr/local/libiconv  
make  
make install  
\--------------------------------------------------------------  
tar -zxvf libmcrypt-2.5.8.tar.gz   
cd libmcrypt-2.5.8  
./configure  
make  
make install  
sleep 2  
/sbin/ldconfig  
cd libltdl  
./configure --enable-ltdl-install  
make  
make install  
cd ../../  
  
hp在make过程中出现“usr bin ld cannot find lltdl”错误，详细错误如下：  
  
/usr/bin/ld: cannot find -lltdl  
collect2: ld returned 1 exit status  
make: \*\*\* \[libphp5.la\] Error 1  
原因：  
在编辑php时添加的“–with-mcrypt”选项造成。  
解决方法：  
如果不需要mcrypt，那么编辑php时去掉该选项，然后再make、make install。  
如果需要mcrypt，那么需要安装libltdl  
libltdl在libmcrypt软件包中就有，具体过程：  
\#cd /software/libmcrypt-2.5.8/libltdl  
\#./configure –enable-ltdl-install  
\#make  
\#make install  
这个时候再回到php的安装目录下进行重新编译php，一切ok  
\---------------------------------------------------------------  
tar -zxvf mhash-0.9.9.9.tar.gz   
cd mhash-0.9.9.9  
 ./configure  
make && make install  
vim /etc/ld.so.conf.d/mhash.conf  \# 做添加mhash的库文件让系统找到，不然后面编译安装mcrypt会报错  
    /usr/local/mhash/lib  
  
rm -f /usr/lib64/libmcrypt.\*  
rm -f /usr/lib64/libmhash\*  
ln -s /usr/local/lib/libmcrypt.la /usr/lib64/libmcrypt.la  
ln -s /usr/local/lib/libmcrypt.so /usr/lib64/libmcrypt.so  
ln -s /usr/local/lib/libmcrypt.so.4 /usr/lib64/libmcrypt.so.4  
ln -s /usr/local/lib/libmcrypt.so.4.4.8 /usr/lib64/libmcrypt.so.4.4.8  
ln -s /usr/local/lib/libmhash.a /usr/lib64/libmhash.a  
ln -s /usr/local/lib/libmhash.la /usr/lib64/libmhash.la  
ln -s /usr/local/lib/libmhash.so /usr/lib64/libmhash.so  
ln -s /usr/local/lib/libmhash.so.2 /usr/lib64/libmhash.so.2  
ln -s /usr/local/lib/libmhash.so.2.0.1 /usr/lib64/libmhash.so.2.0.1  
ln -s /usr/local/lib/libiconv.so.2 /usr/lib64/  
\-----------------------------------------------------------------  
  
  
tar zxvf mcrypt-2.6.8.tar.gz  
cd mcrypt-2.6.8/  
/sbin/ldconfig   
./configure LD\_LIBRARY\_PATH=/usr/local/lib  
make  
make install  
cd ../  
\-----------------------------------------------------------------  
  
3、php安装  
yum -y install libxslt\*  
 tar -zxvf php-5.3.27.tar.gz   
 cd php-5.3.27  
./configure  
./configure \\  
\--prefix=/data/soft/php-5.3.27 \\  
\--with-mysql=/data/mysql \\  
\--with-iconv-dir=/usr/local/libiconv \\  
\--with-freetype-dir \\  
\--with-jpeg-dir \\  
\--with-png-dir \\  
\--with-zlib \\  
\--with-libxml-dir=/usr \\  
\--enable-xml \\  
\--disable-rpath \\  
\--enable-safe-mode \\  
\--enable-bcmath \\  
\--enable-shmop \\  
\--enable-sysvsem \\  
\--enable-inline-optimization \\  
\--with-curlwrappers \\  
\--enable-mbregex \\  
\--enable-mbstring \\  
\--enable-fpm \\  
\--with-mcrypt \\  
\--with-gd \\  
\--enable-gd-native-ttf \\  
\--with-openssl \\  
\--with-mhash \\  
\--enable-pcntl \\  
\--enable-sockets \\  
\--with-xmlrpc \\  
\--enable-zip \\  
\--enable-soap \\  
\--enable-short-tags \\  
\--enable-zend-multibyte \\  
\--enable-static \\  
\--with-xsl \\  
\--with-fpm-user=nginx \\  
\--with-fpm-group=nginx \\  
\--enable-ftp  
  
  
注意：在make前加上这两条命令：  
ln -s /data/mysql/lib/libmysqlclient.so.18 /usr/lib64/   
touch  ext/phar/phar.phar    
  
make  && make install     
  
ln -s /data/php-5.3.27/  /data/php/   
  
配置php解析配置文件   (开发环境打开log，生产环境全部关闭)  
\[root@nginx php\]\# diff php.ini-\*  
521c521  
< error\_reporting = E\_ALL | E\_STRICT  
\---

配置php配置文件  
\[root@nginx data\]\# ln -s soft/php-5.3.27 ./php  
把生产环境copy到php下的lib

request\_slowlog\_timeout = 10  
php\_admin\_value\[sendmail\_path\] = /usr/sbin/sendmail -t -i -f 1098331428@qq.com  （发邮件）  
  
vimdiff比对两个文件  
\[root@nginx etc\]\# vimdiff php-fpm.conf php-fpm.conf.default  
检查语法

编辑开机自动启动脚本  
\[root@nginx etc\]\# vi /etc/rc.local  
\#!/bin/sh  
\#  
\# This script will be executed \*after\* all the other init scripts.  
\# You can put your own initialization stuff in here if you don't  
\# want to do the full Sys V style init stuff.  
  
touch /var/lock/subsys/local  
/etc/init.d/mysqld start  
/data/php/sbin/php-fpm  
/data/nginx/sbin/nginx  
  
\[root@nginx etc\]\# netstat -lntup | grep php-fpm

3、整合php和nginx以下两种方法  
        \#location ~ \\.php$ \{  
        \#    proxy\_pass   http://127.0.0.1;  
        \#\}  
  
        \# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000  
        \#  
        \#location ~ \\.php$ \{  
        \#    root           html;  
        \#    fastcgi\_pass   127.0.0.1:9000;  
        \#    fastcgi\_index  index.php;  
        \#    fastcgi\_param  SCRIPT\_FILENAME  /scripts$fastcgi\_script\_name;  
        \#    include        fastcgi\_params;  
        \#\}  
粘贴到配置bbs配置文件   
\[root@nginx extra\]\# sed -n '8,19p' bbs.conf    
        \#location ~ \\.php$ \{  
        \#    root           html;  
        \#    fastcgi\_pass   127.0.0.1:9000;  
        \#    fastcgi\_index  index.php;  
        \#    fastcgi\_param  SCRIPT\_FILENAME  /scripts$fastcgi\_script\_name;  
        \#    include        fastcgi\_params;  
        \#\}  
\[root@nginx extra\]\# sed -i '8,14s/\#//g' bbs.conf     替换  
\[root@nginx extra\]\# cat bbs.conf   
        server \{  
        listen       80;  
        server\_name  bbs.wolf.com;  
        location / \{  
            root   html/bbs;  
            index  index.html index.htm;  
            access\_log logs/bbs\_access.log;  
        location ~ \\.php$ \{  
            root           html;  
            fastcgi\_pass   127.0.0.1:9000;  
            fastcgi\_index  index.php;  
            fastcgi\_param  SCRIPT\_FILENAME  /scripts$fastcgi\_script\_name;  
            include        fastcgi\_params;  
        \}  
        \}  
    \}  
\[root@nginx extra\]\# /data/nginx/sbin/nginx -t  
nginx: the configuration file /data/nginx1.8.1/conf/nginx.conf syntax is ok  
nginx: configuration file /data/nginx1.8.1/conf/nginx.conf test is successful  
\[root@nginx extra\]\# /data/nginx/sbin/nginx -s reload  
  
bbs首页加入index.php  
   
\[root@nginx bbs\]\# vi /data/nginx/conf/extra/bbs.conf   
        server \{  
        listen       80;  
        server\_name  bbs.wolf.com;  
        location / \{  
            root   html/bbs;  
            index  index.php index.html index.htm;  
            access\_log logs/bbs\_access.log;  
        \#location ~ .\* \\. (php|php5)?$  
        location ~ .\*\\.(php|php5)?$  
        \{  
        \#    root           html/bbs;  
            fastcgi\_pass   127.0.0.1:9000;  
            fastcgi\_index  index.php;  
         \#   fastcgi\_param  SCRIPT\_FILENAME  /scripts$fastcgi\_script\_name;  
            include        fastcgi.conf;  
        \#\}  
        \}  
    \}  
\}  
  
  
在nginx站点目录下写一个index.php代码测试php  
<?php  
    phpinfo();  
?>  
  
输入http://bbs.wolf.com/访问  
  
  
需要连接数据库  
\[root@nginx bbs\]\# vi wolf\_mysql.php    
<?php  
$link=mysql\_connect('localhost','root','123') or mysql\_error();  
if(!$link)  echo "failed!";  
else echo "ok! \\n";  
mysql\_close();  
?>  
  
测试  
http://bbs.wolf.com/wolf\_mysql.php  
服务器上测试  
\[root@nginx bbs\]\# /data/php/bin/php wolf\_mysql.php   
ok!   
\[root@nginx bbs\]\#  
=====================================================  
资料  
找到以下配置段  
location ~ .\*\\.(php|php5)?$  
\{  
try\_files $uri =404;  
fastcgi\_pass  unix:/tmp/php-cgi.sock;  
fastcgi\_index index.php;  
include fcgi.conf;  
\}  
默认是匹配php与php5结尾的，去掉php5后缀的匹配，只匹配php的。  
location ~ .\*\\.php$  
\{  
try\_files $uri =404;  
fastcgi\_pass  unix:/tmp/php-cgi.sock;  
fastcgi\_index index.php;  
include fcgi.conf;  
\}
