云中漫步

　　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
COMMAND  PID   USER  FD   TYPE DEVICE SIZE/OFF NODENAME
httpd   1567   root   4u  IPv6  11482     0t0  TCP *:http (LISTEN)
httpd   1570 daemon    4u IPv6  11482      0t0 TCP *:http (LISTEN)
httpd   1571 daemon    4u IPv6  11482      0t0 TCP *:http (LISTEN)
[root@zyl /]#
　　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

freetype-2.3.11-17.el6.x86_64
curl-7.19.7-52.el6.x86_64
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：
./configure --prefix=/application/php5.3.27--with-apxs2=/application/apache/bin/apxs --with-mysql=/application/mysql--with-xmlrpc --with-openssl --with-zlib --with-freetype-dir --with-gd--with-jpeg-dir --with-png-dir --with-iconv=/usr/local/libiconv--enable-short-tags --enable-sockets --enable-zend-multibyte --enable-soap--enable-mbstring --enable-static --enable-gd-native-ttf --with-curl --with-xsl--enable-ftp --with-libxml-dir
1047 yum install openssl-devle -y
　　

　　编译（Configure）出现的错误：
　　1.
checking for pkg-config... /usr/bin/pkg-config
configure: error: Cannotfind OpenSSL's
解决办法：
yum install openssl-devel –y
　　2.
configure: error: xslt-confignot found. Please reinstall the libxslt >= 1.1.0 distribution
解决办法：
yum install libxslt-devel –y

比较两者的区别：

[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.
#

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
