1、Apache的安裝
檢查系統是否自帶httpd（一般自帶版本比較低，卸載掉）
[root@localhost1 software]# rpm -qa httpd*
[root@localhost1 software]#
2、如果沒有自帶 Apache 服務軟體，可以不需要進行下麵的卸載 [root@Centos ~]# rpm -e --nodeps httpd-2.2.15-54.el6.centos.x86_64 warning: /etc/httpd/conf/httpd.conf saved as /etc/httpd/conf/httpd.conf.rpmsave [root@Centos ~]# rpm -e --nodeps httpd-tools-2.2.15-54.el6.centos.x86_64

[root@localhost1 httpd-2.2.34]# cat README Apache HTTP Server What is it? ----------- The Apache HTTP Server is a powerful and flexible HTTP/1.1 compliant web server. Originally designed as a replacement for the NCSA HTTP Server, it has grown to be the most popular web server on the Internet. As a project of the Apache Software Foundation, the developers aim to collaboratively develop and maintain a robust, commercial-grade, standards-based server with freely available source code. The Latest Version ------------------ Details of the latest version can be found on the Apache HTTP server project page under <http://httpd.apache.org/>. Documentation ------------- The documentation available as of the date of this release is included in HTML format in the docs/manual/ directory. The most up-to-date documentation for the 2.2.x releases can be found at <http://httpd.apache.org/docs/2.2/>. Installation ------------ Please see the file called INSTALL. Platform specific notes can be found in README.platforms. Licensing --------- Please see the file called LICENSE. Cryptographic Software Notice #加密軟體的通知 ----------------------------- This distribution may include software that has been designed for use with cryptographic software. The country in which you currently reside may have restrictions on the import, possession, use, and/or re-export to another country, of encryption software. BEFORE using any encryption software, please check your country's laws, regulations and policies concerning the import, possession, or use, and re-export of encryption software, to see if this is permitted. See <http://www.wassenaar.org/> for more information. The U.S. Government Department of Commerce, Bureau of Industry and Security (BIS), has classified this software as Export Commodity Control Number (ECCN) 5D002.C.1, which includes information security software using or performing cryptographic functions with asymmetric algorithms. The form and manner of this Apache Software Foundation distribution makes it eligible for export under the License Exception ENC Technology Software Unrestricted (TSU) exception (see the BIS Export Administration Regulations, Section 740.13) for both object code and source code. The following provides more details on the included files that may be subject to export controls on cryptographic software: Apache httpd 2.0 and later versions include the mod_ssl module under modules/ssl/ for configuring and listening to connections over SSL encrypted network sockets by performing calls to a general-purpose encryption library, such as OpenSSL or the operating system's platform-specific SSL facilities. In addition, some versions of apr-util provide an abstract interface for SSL encrypted network sockets in the files under the directory srclib/apr-util/ssl/ that makes use of a general-purpose encryption library, such as OpenSSL or the operating system's platform-specific SSL facilities. Apache httpd currently does not use that apr-util interface. Some object code distributions of Apache httpd, indicated with the word "crypto" in the package name, may include object code for the OpenSSL encryption library as distributed in open source form from <http://www.openssl.org/source/>. The above files are optional and may be removed if the cryptographic functionality is not desired or needs to be excluded from redistribution. Distribution packages of Apache httpd that include the word "nossl" in the package name have been created without the above files and are therefore not subject to this notice. Contacts -------- o If you want to be informed about new code releases, bug fixes, security fixes, general news and information about the Apache server subscribe to the apache-announce mailing list as described under <http://httpd.apache.org/lists.html#http-announce> o If you want freely available support for running Apache please join the Apache user community by subscribing to Users Mailing List at <http://httpd.apache.org/userslist.html> or one of the following USENET newsgroups: comp.infosystems.www.servers.unix comp.infosystems.www.servers.ms-windows Also available at: <http://groups.google.com/groups?group=comp.infosystems.www.servers> o If you want commercial support for running Apache please contact one of the companies and contractors which are listed at <http://www.apache.org/info/support.cgi> o If you have a concrete bug report for Apache please go to the Apache Group Bug Database and submit your report: <http://httpd.apache.org/bug_report.html> o If you want to participate in actively developing Apache please subscribe to the `[email protected]' mailing list as described at <http://httpd.apache.org/lists.html#http-dev> Acknowledgments ---------------- We wish to acknowledge the following copyrighted works that make up portions of the Apache software: Portions of this software were developed at the National Center for Supercomputing Applications (NCSA) at the University of Illinois at Urbana-Champaign. This software contains code derived from the RSA Data Security Inc. MD5 Message-Digest Algorithm, including various modifications by Spyglass Inc., Carnegie Mellon University, and Bell Communications Research, Inc (Bellcore). Regular expression support is provided by the PCRE library package, which is open source software, written by Philip Hazel, and copyright by the University of Cambridge, England. The original software is available from ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/ Apache 2 relies heavily on the use of autoconf and libtool to provide a build environment.
[root@localhost1 httpd-2.2.34]# cat INSTALL APACHE INSTALLATION OVERVIEW CAUTION ------- This package represents a legacy version of the Apache HTTP Server software and is not current. Please note that Apache Web Server Project will only provide maintenance releases of the 2.2.x flavor through June of 2017, and will provide some security patches beyond this date through at least December of 2017. Minimal maintenance patches of 2.2.x are expected throughout this period, and users are strongly discouraged from deploying this legacy release. #不建議安裝較低版本，因為不會再維護 Also note, this package includes very stale and known-vulnerable versions of the Expat [http://expat.sourceforge.net/] and PCRE [http://www.pcre.org/] packages. Users are strongly encouraged to first install the most recent versions of these components. #強烈建議安裝最新版本 Quick Start - Unix ------------------ For complete installation documentation, see [ht]docs/manual/install.html or http://httpd.apache.org/docs/2.2/install.html $ ./configure --prefix=PREFIX $ make $ make install $ PREFIX/bin/apachectl start NOTES: * Replace PREFIX with the filesystem path under which Apache should be installed. A typical installation might use "/usr/local/apache2" for PREFIX (without the quotes). * If you are a developer who will be linking your code with Apache or using a debugger to step through server code, ./configure's --with-included-apr option may be advantageous, as it removes the possibility of version or compile-option mismatches with APR and APR-util code. (Many OSes now include their own version of APR and APR-util.) * If you are a developer building Apache directly from Subversion, you will need to run ./buildconf before running configure. This script bootstraps the build environment and requires Python as well as GNU autoconf and libtool. If you build Apache from a release tarball, you don't have to run buildconf. * If you want to build a threaded MPM (for instance worker) on FreeBSD, be aware that threads do not work well with Apache on FreeBSD versions before 5.4-RELEASE. If you wish to try a threaded Apache on an earlier version of FreeBSD, use the --enable-threads parameter to ./configure in addition to the --with-mpm parameter. * If you are building directly from Subversion on Mac OS X (Darwin), make sure to use GNU Libtool 1.4.2 or newer. All recent versions of the developer tools on this platform include a sufficiently recent version of GNU Libtool (named glibtool, but buildconf knows where to find it). For a short impression of what possibilities you have, here is a typical example which configures Apache for the installation tree /sw/pkg/apache with a particular compiler and flags plus the two additional modules mod_rewrite and mod_speling for later loading through the DSO mechanism: $ CC="pgcc" CFLAGS="-O2" \ ./configure --prefix=/sw/pkg/apache \ --enable-rewrite=shared \ --enable-speling=shared The easiest way to find all of the configuration flags for Apache 2.2 is to run ./configure --help. Quick Start - Windows --------------------- For complete documentation, see manual/platform/windows.html.en or http://httpd.apache.org/docs/2.2/platform/windows.html. The Apache/Win32 binaries are distributed as Windows Installer packages (.msi) named httpd-2.2.xx-win32-x86-no_ssl.msi for a version without mod_ssl and httpd-2.2.xx-win32-x86-openssl-0.9.8x.msi for a version including the mod_ssl plus the openssl library and command line utility. These packages may be unpacked without "installing" them by using the msiexec /a option. If you have unpacked a source distribution (named httpd-2.2.x-win32-src.zip, without any -x86 notation) you must compile the package yourself, see the links mentioned above. Unless you intended to do this, please look again for the binary package from http://www.apache.org/dist/httpd/binaries/win32/ and install the desired .msi package. The .msi package configures the httpd.conf file, and installs and starts the Apache2.2 service for you. It also installs plenty of useful shortcuts and the taskbar ApacheMonitor. We strongly encourage you to use it. Postscript ---------- The Apache HTTP Server group cannot field user's installation questions. There are many valuable forums to help you get started. Please refer your questions to the appropriate forum, such as the Users Mailing List at http://httpd.apache.org/userslist.html or the usenet newsgroups comp.infosystems.www.servers.unix or comp.infosystems.www.servers.ms-windows. Thanks for using the Apache HTTP Server, version 2.2. The Apache Software Foundation http://www.apache.org/
