How linux installs the apache server

Editor to share with you how to install linux apache server, I believe that most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

Compressed package installation mode

1. Download httpd-2.4.29.tar.gz

2. Upload to server / usr/local/software

Tar-zxvf httpd-2.4.29.tar.gz./configure-- prefix=/usr/local/apache2/ # set up the apache installation directory

If Apr is not installed, an error will be reported:

Checking for APR... Noconfigure: error: APR not found. Please read the documentation.

3. After installing apr, download apr-1.6.3.tar.gz first

4. Upload to server / usr/local/software

Tar-zxvf apr-1.6.3.tar.gzcd apr-1.6.3.configuremakemake install

Will report an error again:

Checking for APR-util... Noconfigure: error: APR-util not found. Please read the documentation.

5. Download apr-util-1.6.1.tar.gz

6. Upload to server / usr/local/software

Tar-zxvf apr-util-1.6.1.tar.gzcd apr-util-1.6.1./configure-prefix=/usr/local/apr-util/-with-apr=/usr/local/apr

An error will also be reported at this time:

Xml/apr_xml.c:35:19: fatal error: expat.h: no compilation break for that file or directory # include ^. Make: * * [xml/apr_xml.lo] error 1

7. Guess that the development library may be short of expat.

Yum install expat-devel # will let you type y./configure-- prefix=/usr/local/apr-util/-- with-apr=/usr/local/aprmake # successfully! Make install

8. When you go back to install apache, you should specify not only the path of apr, but also the path of apr-util

. / configure-- prefix=/usr/local/apache2/-- with-apr=/usr/local/apr/-- with-apr-util=/usr/local/apr-util/

Still reported an error, many people may have collapsed here, but this mistake is similar to the one encountered before.

Checking for pcre-config... Falseconfigure: error: pcre-config for libpcre not found. PCRE is required and available from http://pcre.org/

9. Download pcre-8.41.tar.gz

10. Upload to server / usr/local/software

Tar-zxvf pcre-8.41.tar.gz./configure

It's wrong again. I promise this is the last time.

Checking windows.h usability... Nochecking windows.h presence... Nochecking for windows.h... Noconfigure: error: You need a C++ compiler for C++ support.

10. Install C++ environment

Yum install-y gcc gcc-c++# has been wrong so many times, don't forget where it is now, and then install pcre./configuremakemake install.

11. Well, after a big circle, the next step is to install apache

Cd.. cd apache./configure-prefix=/usr/local/apache2/-with-apr=/usr/local/apr/-with-apr-util=/usr/local/apr-util/makemake install

How miserable! The last step is to report an error:

/ usr/local/apr-util//lib/libaprutil-1.so: undefined reference to `XML_GetErrorCode' / usr/local/apr-util//lib/libaprutil-1.so: undefined reference to `XML_SetEntityDeclHandler' / usr/local/apr-util//lib/libaprutil-1.so: undefined reference to `XML_ParserCrecollect2: error: ld returned 1 exit statusmake [2]: * * [htpasswd] error 1make [2]: Leaving directory `/ usr/local/software/apache/support'make [ 1]: * * [all-recursive] error 1make [1]: Leaving directory `/ usr/local/software/apache/support'

I have never seen this kind of error report, and I did a decisive online search, and the answer is: the apr version is too high.

So I downloaded apr-util-1.5 http://archive.apache.org/dist/apr/apr-util-1.5.2.tar.gz

13. Upload to server / usr/local/software

Tar-zxvf apr-util-1.5.2.tar.gzcd apr-util-1.5.2./configure-prefix=/usr/local/apr-util-1.5/-with-apr=/usr/local/aprmakemake install

Repeat step 11, the only difference is that the configuration now specifies: apr-util-1.5, which is very important!

Cd.. cd apache./configure-- prefix=/usr/local/apache2/-- with-apr=/usr/local/apr/-- with-apr-util=/usr/local/apr-util-1.5/make # make time will be longer make install

Perfect ending:

Installing configuration filesmkdir / usr/local/apache2/confmkdir / usr/local/apache2/conf/extramkdir / usr/local/apache2/conf/originalmkdir / usr/local/apache2/conf/original/extraInstalling HTML documentsmkdir / usr/local/apache2/htdocsInstalling error documentsmkdir / usr/local/apache2/errorInstalling iconsmkdir / usr/local/apache2/iconsmkdir / usr/local/apache2/logsInstalling CGIsmkdir / usr/local/apache2/cgi-binInstalling header filesmkdir / usr/local/apache2/includeInstalling build system filesmkdir / usr/local/apache2/buildInstalling man pages and online manualmkdir / usr/ Local/apache2/manmkdir / usr/local/apache2/man/man1mkdir / usr/local/apache2/man/man8mkdir / usr/local/apache2/manualmake [1]: Leaving directory `/ usr/local/software/apache'

15. Enter the configuration file location: / usr/local/apache2/conf

Cp httpd.conf httpd.conf.bak # backup configuration file vim httpd.conf# release the comment on line 191 and change it to: ServerName [your IP]: 80:wq

16. Start apache

/ usr/local/apache2/bin/apachectl start# or / usr/local/apache2//bin/httpd-k start

Turn off the firewall, enter the server's ip in the browser's address bar and the web page will appear: It works!

17. Close apache

Ps-ef | grep apache/usr/local/apache2/bin/apachectl stop# or / usr/local/apache2//bin/httpd-k stop# Yes, there is / / in front of bin

This way of installing original files is too complicated. In fact, there is another way to install apache services. I don't know if there is any conflict with my previous installation. I also have a try today.

Yum source installation mode

1. Yum source installation (network download is required)

First, during the intermediate process of shutting down apache service yum install httpd #, enter: y

Result:

Installed as a dependency:

Apr.x86_64 0VOR 1.4.8-3.el7_4.1 apr-util.x86_64 0RU 1.5.2-6.el7 httpd-tools.x86_64 0RU 2.4.6-67.el7.centos.6 mailcap.noarch 0Rl 2.1.41-2.el7 over!

2. The installation location of yum is at: / etc/httpd/conf. After I enter the backup configuration file, the modification is different from that before. It is on line 95, for reference only.

Cd / etc/httpd/confcp httpd.conf httpd.conf.bak# drop the comment on line 95 and change it to: ServerName [your IP]: 80:wq

3. Start the service

Systemctl start httpd.service

Enter ip in the browser and the apache preset html appears, perfect!

4. Shut down the service

Systemctl stop httpd.service

5. I will start the httpd installed in the first way again

/ usr/local/apache2/bin/apachectl start

Refresh the browser suddenly appeared: It worksinstalled, indicating that the two installation methods do not conflict.

The above is all about how linux installs the apache server. Thank you for reading! I believe we all have a certain understanding, hope to share the content to help you, if you want to learn more knowledge, welcome to follow the industry information channel!
