安装php的程序环境

检查apache及mysql的安装情况

[root@zyl /]# lsof  -i :3306

COMMAND  PID  USER  FD   TYPE DEVICE SIZE/OFF NODENAME

mysqld  1743 mysql   10u IPv4  12158      0t0 TCP *:mysql(LISTEN)

[root@zyl /]# lsof  -i :80

apache和mysql必须安装好才能安装php

检查安装php所需lib库

[root@zyl /]# yum  install  zlib libxml libjpeg freetype libpng gd  curl libiconv zlib-devel libxml2-devel libjpeg-devel freetype-devel libpng-devel gd-develcurl-devel –y

[root@zyl /]# rpm -qa  zlib libxml libjpeg freetype libpng gd  curl libiconv zlib-devel libxml2-devel libjpeg-devel freetype-devel libpng-develgd-devel curl-devel

安装libiconv

[root@zyl /]# wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.14.tar.gz

[root@zyl libiconv-1.14]# ./configure --prefix=/usr/local/libiconv

[root@zyl libiconv-1.14]# make && make install

[root@zyl libiconv-1.14]# cd ../

开始安装php

rz -y

tar xf php-5.3.27.tar.gz

cd php-5.3.27

编译：

 1047 yum install openssl-devle -y

编译（Configure）出现的错误：

1.

configure: error: Cannotfind OpenSSL's <evp.h>

解决办法：

yum install openssl-devel –y

2.

[root@zyl php-5.3.27]#
拷贝php配置文件到php默认目录并更改文件名称为php。ini：

[root@zyl php-5.3.27]# cpphp.ini-production /application/php/lib/php.ini ===========》》php的配置文件

小结：

1.      正式配置文件一般关闭LOG，不输出LOG

2.      php的配置文件目录：/application/php/lib

配置apache支持php

安装php默认产生的文件及配置

 [root@zyl /]# ll /application/apache/modules/

total 28888

-rw-r--r-- 1 root root     9115Jul  7 00:42 httpd.exp

-rwxr-xr-x 1 root root 29566389 Jul 9 20:18 libphp5.so

[root@zyl /]# grep libphp5 /application/apache/conf/httpd.conf

LoadModule php5_module       modules/libphp5.so

执行下面的命令编辑apache的主配置文件http.conf

[root@zyl php-5.3.27]# cd /application/apache/conf/

[root@zyl conf]# cp httpd.confhttpd.conf.ori    ===========è> 养成备份的好习惯

[root@zyl apache]# vi/application/apache/conf/httpd.conf     ====切换到  311gg，添加如下

AddType application/x-httpd-php .php.phtml

AddType application/x-httpd-php .source.phps

：wq

修改damon用户为ett

[root@zyl apache]# vi/application/apache/conf/httpd.conf      ====切换到  65gg，添加如下

# running httpd, as with most system services.

#

User daemon   ========== www

Group daemon  ========== www

注意:如果不存在www用户，一会保存好配置，需要执行useradd www –M -s /sbin/nologin 建立www。

然后转到166行修改默认的首页文件，本例中添加一个index.php:

# is requested.

#

<IfModule dir_module>

DirectoryIndexindex.php index.html

提示：养成备份的习惯，再就是可以diff（比对文件）

[root@zyl conf]# diff httpd.confhttpd.conf.

httpd.conf.20160712  httpd.conf.bak       httpd.conf.ori

[root@zyl conf]# diff httpd.confhttpd.conf.ori
