安装php-5.3.28 时问题
在linux下安装php时，（我安装的时5.2.6）phptar.gz压缩包解压缩之后。
在分配路径和关联扩展包时遇到错误如下：
--------------------------------------------------------
Sorry, I cannot run apxs. Possible reasons follow:
1. Perl is not installed
2. apxs was not found. Try to pass the path using --with-apxs2=/path/to/apxs
3. Apache was not built using --enable-so (the apxs usage page is displayed)
---------------------------------------------------
解决步骤：
1、根据不能run apxs 。cd 到apache的bin目录下运行./apxs 运行结果
----------------------------------------------------
bash: ./apxs: /replace/with/path/to/perl/interpreter: bad interpreter: No such file or directory
---------------------------------------------------------
2、vim apxs文件 找“/replace/with/path/to/perl/interpreter”关键字
在第一个行 ：#!/replace/with/path/to/perl/interpreter -w
根据perl的安装目录 /usr/bin/perl
修改为：#! /usr/bin/perl -w
3、运行第一步。或者直接 ./configure ^^^^^
问题解决
configure 代码如下：
./configure--prefix=/usr/local/php/--with-config-file-path=/usr/local/php/etc/--with-apxs2=/usr/local/apache2/bin/apxs--with-mysql=/usr/local/mysql/--with-libxml-dir=/usr/local/libxml2/--with-jpeg-dir=/usr/local/jpeg6/--with-freetype-dir=/usr/local/freetype/--with-gd=/usr/local/gd2/--with-mcrypt=/usr/local/libmcrypt/--with-mysqli=/usr/local/mysql/bin/mysql_config--enable-soap--enable-mbstring=all--enable-sockets
总结一下用源代码安装LAMP环境中遇到常见的错误，从错误3开始是因为安装php后面带参数，导到没有找到开发包例如:./configure --with-gd --with-libjpeg会出现如下错误。
1.checking for termcap functions library... configure: error: No curses/termcap library found
解决方法:yum install ncurses --缺少ncurses安装包
2.1)安装gd库出现以下错误:
In file included from /root/php-5.3.6/ext/gd/libgd/gd_compat.c:8:
/usr/local/jpeg/include/jpeglib.h:938: error: expected declaration specifiers or ‘...’ before ‘FILE’
/usr/local/jpeg/include/jpeglib.h:939: error: expected declaration specifiers or ‘...’ before ‘FILE’
make: *** [ext/gd/libgd/gd_compat.lo] Error 1
解决方法:vim php-5.3.6/ext/gd/libgd/gd_compat.c
#include <png.h> --修改为#include </usr/local/libpng/include/png.h>
#include <stdio.h> --添加这行
3. Configure: error: xml2-config not found. Please check your libxml2 installation.
Solutions :
解决方法:yum install libxml2 libxml2-devel
4. Configure: error: Please reinstall the BZip2 distribution
Solutions :
解决方法:yum install bzip2 bzip2-devel
5. Configure: error: libjpeg.(also) not found.
Solutions :
解决方法:yum install libjpeg libjpeg-devel
6.Configure: error: libpng.(also) not found.
Solutions :
解决方法:yum install libpng libpng-devel
7.Configure: error: Cannot find MySQL header files under /usr.
Note that the MySQL client library is not bundled anymore!
Solutions:
解决方法:yum install mysql-devel
8.没有安装snmp开发包
checking for SNMP support... yes
checking OpenSSL dir for SNMP... no
checking whether to enable UCD SNMP hack... no
checking for net-snmp-config... (cached) /usr/bin/net-snmp-config
configure: error: snmp.h not found. Check your SNMP installation.
[root@RedHat1 php-5.2.17]#
解决方法:yum install net-snmp net-snmp-devel
9.apache端口被占用了
[root@redhat1 bin]# ./httpd
(98)Address already in use: make_sock: could not bind to address [::]:80
(98)Address already in use: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
Unable to open logs
[root@redhat1 bin]#
解决方法:80端口被占用了,杀掉占用80端口的进程
10.没有指定主机IP地址
[root@redhat1 bin]# ./httpd
httpd: Could not reliably determine the server's fully qualified domain name, using 2.2.2.117 for ServerName
[root@redhat1 bin]#
解决方法:vim /usr/local/apache/conf/httpd.conf
ServerName localhost --添加这一行就可以了
10.访问网站时出现下载页面
解决方法:vim /usr/local/apache/conf/httpd.conf --加载php模块
LoadModule php5_module modules/libphp5.so
