PHP安装攻略linux二
b>四、如何从RPM包进行安装和配置
在很多Linux的发行版本中都捆绑了apache、php3和MySQL,由于MySQL本身是以RPM格式分发的,因此其安装上面已经介绍,下面仅介绍apache和php的安装和配置。本文基于RedHat Linux 6.1。PHP的设计者不建议从RPM配置php3,但它将在php4中解决这个问题。由于从RPM重新配置和安装php比较麻烦,所以以下方法仅供参考。
1、你需要的rpm文件
为了重新配置和编译php,你应该下载php3的源代码rpm:php-3.0.12.6.src.rpm。该软件包可生成下列rpm:
php-3.0.12-6.i386.rpm php-manual-3.0.12-6.i386.rpm
php-imap-3.0.12-6.i386.rpm php-ldap-3.0.12-6.i386.rpm
php-pgsql-3.0.12-6.i386.rpm
在安装新的rpm之前,你应该首先删除已经的php软件包:
rpm -e php-imap php-ldap php-pgsql php php-manual
重新编译php需要以下软件包:
apache apache-devel
postgresql postgresql-devel
MySQL-devel
2、重新配置、编译和安装php3
安装php3源代码包:
rpm -i php-3.0.12-6.src.rpm
它将php源代码安装在/usr/src/redhat目录下,进入该目录,按下面的命令进行配置和编译:
cd /usr/src/redhat/SPECS
vi php.spec
编辑php.spec文件,找到%build小节,在关于./configure的选项部分加入:
with-mysql=/usr
选项,它指出php支持MySQL数据库。
%build
cd imap-4.5
make RPM_OPT_FLAGS="$RPM_OPT_FLAGS" lnp
cd ..
autoconf
CFLAGS="-fPIC" ./configure --prefix=/usr
with-apxs=/usr/sbin/apxs
with-config-file-path=/etc/httpd
enable-safe-mode
with-exec-dir=/usr/bin
with-system-regex
disable-debug
with-zlib
enable-debugger
enable-magic-quotes
with-mysql=/usr
enable-track-vars
保存修改,重建rpm包:
rpm -bb /usr/src/redhat/SPECS/php.spec
最后,在/usr/src/redhat/RPMS/i386目录下可以找到相应的二进制rpm包,重新安装它们:
rpm -i /usr/src/redhat/RPMS/i386/*
3、配置httpd.conf和srm.conf
在安装好php后,你应该配置httpd以便支持php3脚本。首先编辑/etc/httpd/conf/httpd.conf,找出下列两行,去掉它们前面的注释符#:
AddModule mod_php3.c
LoadModule php3_module modules/libphp3.so
在编译/etc/httpd/conf/srm.conf,去掉下面一行的注释符#:
AddType application/x-httpd-php3 .php3
这样,httpd对于以.php3结尾的文件视为php脚本文件。
4、测试
你可以用上面的两个例子做测试。
5、总结
RedHat等一些Linux发行商虽然在它们的分发中捆绑了上述三个软件包,但php的rpm包初始是不支持MySQL数据库的。另外,原来的mod_php3或mod_php的使用方式已经过时,而新的格式是libphp3.so,因此在RedHat标准的二进制分发中已经不包含mod_php3或mod_php了。
如果你想一直使用这三个软件的最新版本,前二种方法最适用。
上述只是介绍了这三个软件的安装,你必须配置php和MySQL的安全性设置。

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

The five basic components of the Linux system are: 1. Kernel, 2. System library, 3. System utilities, 4. Graphical user interface, 5. Applications. The kernel manages hardware resources, the system library provides precompiled functions, system utilities are used for system management, the GUI provides visual interaction, and applications use these components to implement functions.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and content management systems, and Python is suitable for data science, machine learning and automation scripts. 1.PHP performs well in building fast and scalable websites and applications and is commonly used in CMS such as WordPress. 2.

To view the Git repository address, perform the following steps: 1. Open the command line and navigate to the repository directory; 2. Run the "git remote -v" command; 3. View the repository name in the output and its corresponding address.

Although Notepad cannot run Java code directly, it can be achieved by using other tools: using the command line compiler (javac) to generate a bytecode file (filename.class). Use the Java interpreter (java) to interpret bytecode, execute the code, and output the result.
