PHP安裝

一、下載php源碼包

http://www.php.net/downloads.php

 

2 、安裝php

tar -xvf php-5.5.13.tar.bz2

cd php-5.5.13

./configure --prefix=/usr/local/php --with-config-file-path=/etc --enable-inline-optimization --disable-debug --disable-rpath --enable-shared --enable-opcache --enable-fpm --with-fpm-user=www --with-fpm-group=www --with-mysql=mysqlnd --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --with-gettext --enable-mbstring --with-iconv --with-mcrypt --with-mhash --with-openssl --enable-bcmath --enable-soap --with-libxml-dir --enable-pcntl --enable-shmop --enable-sysvmsg --enable-sysvsem --enable-sysvshm --enable-sockets --with-curl --with-zlib --enable-zip --with-bz2 --with-readline --without-sqlite3 --without-pdo-sqlite --with-pear

make 

make install 

（1）出現錯誤: congigure error: xml2-config not found.

         解決辦法: sudo yum install libxml2-devel

（2）出現錯誤: congigure error: Cannot find OpenSSL's <evp.h>

         解決辦法: yum install openssl openssl-devel

                         ln -s /usr/lib64/libssl.so /usr/lib/

（3）出現錯誤: configure: error: Please reinstall the BZip2 distribution

         解決辦法: yum install bzip2 bzip2-devel

（4）出現錯誤: configure: error: Please reinstall the libcurl distribution -easy.h should be in <curl-dir>/include/curl/

         解決辦法: yum -y install curl-devel

                          configure: error: mcrypt.h not found. Please reinstall libmcrypt.

                          sudo yum install libmcrypt libmcrypt-devel mcrypt mhash

                          configure: error: Please reinstall readline - I cannot find readline.h
                          sudo yum install readline-devel

 

三、添加 PHP 命令到環境變量

vim /etc/profile

在末尾加入

PATH=$PATH:/usr/local/php/bin

export PATH

要使改動當即生效執行

. /etc/profile 或 source /etc/profile

查看環境變量

echo $PATH

 

四、查看php版本

php -v 

PHP 5.5.13 (cli) (built: Jun 20 2014 11:11:26)
Copyright (c) 1997-2014 The PHP Group
Zend Engine v2.5.0, Copyright (c) 1998-2014 Zend Technologies

 

五、配置php-fpm

cd /usr/local/php/etc

cp php-fpm.conf.default php-fpm.conf

 

六、啓動php-fpm

sudo /usr/local/php/sbin/php-fpm

修改nginx的配置文件(/etc/nginx/conf.d/default.conf)

location / {

root web根目錄;

index index.html index.htm index.php;

}

location ~ \.php$ {

root html;

fastcgi_pass 127.0.0.1:9000;

fastcgi_index index.php;

fastcgi_param SCRIPT_FILENAME web根目錄$fastcgi_script_name;

include fastcgi_params;

}

 

七、重啓nginx

/etc/init.d/nginx restart

在web根目錄下建立index.php

<?php echo phpinfo(); ?>

在瀏覽器中輸入http://ip/index.php查當作功便可。

（1）出現錯誤: can not get uid for www

解決方法：

修改php-fpm.conf中user爲nginx group爲nginx
