This article introduces RedHat 7 how to install HTTPD, the content is very detailed, interested friends can refer to, hope to be helpful to you.

1. View operating system version

[root@aws srclib] # cat / etc/redhat-release

Red Hat Enterprise Linux Server release 7.4 (Maipo)

two。 Install apr first. This example is version 1.6.3.

Wget http://mirrors.cnnic.cn/apache/apr/apr-1.6.3.tar.gz

After download, it will be decompressed.

Tar-xzvf apr-1.6.3.tar.gz

Go to the apr directory and execute the configure command, which is a parameter in this example and sets the installation directory

Cd / usr/local/src/apr-1.6.3

. / configure-- prefix=/usr/local/apr

Once configured, execute make and make install

Make & & make install

3. Install apr-util, the version of this example is 1.6.1

Wget http://mirrors.cnnic.cn/apache/apr/apr-util-1.6.1.tar.bz2

You may encounter an error during decompression:

[root@aws src] # tar-jxvf apr-util-1.6.1.tar.bz2

Tar (child): bzip2: Cannot exec: No such file or directory

Tar (child): Error is not recoverable: exiting now

Tar: Child returned status 2

Tar: Error is not recoverable: exiting now

The solution is:

Yum-y install bzip2

Next, just like installing apr, run the configure command first

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

Then execute the installation command:

Make & & make install

You may encounter the following errors during installation:

Pr_xml.lo-c xml/apr_xml.c & & touch xml/apr_xml.lo

Xml/apr_xml.c:35:19: fatal error: expat.h: No such file or directory

# include

^

Compilation terminated.

Make [1]: * * [xml/apr_xml.lo] Error 1

Make [1]: Leaving directory `/ usr/local/src/apr-util-1.6.1

The solution is to install the expat library

Yum install expat-devel

4. Install httpd

This example uses version 2.4.29

Wget http://mirrors.cnnic.cn/apache/httpd/httpd-2.4.29.tar.gz

Similarly, after download, it will be decompressed.

Tar-xvzf httpd-2.4.29.tar.gz

Enter the directory and execute the configure command

/ configure-- prefix=/usr/local/apache2.4-- with-apr=/usr/local/apr-- with-apr-util=/usr/local/apr-util-- enable-so-- enable-mods-shared=most-- with-included-apr

Enable-so means to enable DSO, that is, to present certain functions in the form of so

-- enable-mods-shared=most means that most functional modules are installed in a shared manner, which you will see in the modules directory after installation.

If you encounter the following error:

Checking for gcc option to accept ISO C99... -std=gnu99

Checking for pcre-config... False

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

The solution is:

Yum install-y pcre pcre-devel

Finally compile and install

Make

Make install

Either of the above steps can be done with the command echo $? To check whether the execution was successful.

An error may be reported in make as follows:

/ 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_ParserCreate'

/ usr/local/apr-util/lib/libaprutil-1.so: undefined reference to `XML_SetCharacterDataHandler'

/ usr/local/apr-util/lib/libaprutil-1.so: undefined reference to `XML_ParserFree'

/ usr/local/apr-util/lib/libaprutil-1.so: undefined reference to `XML_SetUserData'

/ usr/local/apr-util/lib/libaprutil-1.so: undefined reference to `XML_StopParser'

/ usr/local/apr-util/lib/libaprutil-1.so: undefined reference to `XML_Parse'

/ usr/local/apr-util/lib/libaprutil-1.so: undefined reference to `XML_ErrorString'

/ usr/local/apr-util/lib/libaprutil-1.so: undefined reference to `XML_SetElementHandler'

Collect2: error: ld returned 1 exit status

Make [2]: * * [htpasswd] Error 1

Make [2]: Leaving directory `/ usr/local/src/httpd-2.4.29/support'

Make [1]: * * [all-recursive] Error 1

Make [1]: Leaving directory `/ usr/local/src/httpd-2.4.29/support'

Make: * * [all-recursive] Error 1

The solution is:

Cp-rf / usr/local/src/apr-1.6.3 / usr/local/src/httpd-2.4.29/srclib/apr

Cp-rf / usr/local/src/apr-util-1.6.1 / usr/local/src/httpd-2.4.29/srclib/apr-util

5. At this point, the httpd installation is complete.

You can view which modules are installed with the following command:

[root@aws srclib] # / usr/local/apache2.4/bin/apachectl-M

Loaded Modules:

Core_module (static)

So_module (static)

Http_module (static)

Mpm_event_module (static)

Authn_file_module (shared)

Authn_core_module (shared)

Authz_host_module (shared)

Authz_groupfile_module (shared)

Authz_user_module (shared)

Authz_core_module (shared)

Access_compat_module (shared)

Auth_basic_module (shared)

Reqtimeout_module (shared)

Filter_module (shared)

Mime_module (shared)

Log_config_module (shared)

Env_module (shared)

Headers_module (shared)

Setenvif_module (shared)

Version_module (shared)

Unixd_module (shared)

Status_module (shared)

Autoindex_module (shared)

Dir_module (shared)

Alias_module (shared)

Php5_module (shared)

The word shared indicates that the module is a dynamic sharing module; static is a static module.

The difference between dynamic and static is that static modules are directly bound to the main program (/ usr/local/apache2.4/bin/httpd), which we cannot see, while dynamic modules are independent files, that is, .so files in the modules directory.

6. Configure httpd to support php

a. Edit the httpd.conf file (/ usr/local/apache2.4/conf/httpd.conf), search for ServerName, and remove the # before ServerName www.example.com:80

b. Find the following

AllowOverride none

Require all denied

Modify to

AllowOverride none

Require all granted

c. Search the following line again.

AddType application/x-gzip .gz .tgz

Add at the bottom of the line above

AddType application/x-httpd-php .php

d. Find the following paragraph

DirectoryIndex index.html

Modify to

DirectoryIndex index.html index.php

7. Check whether the configuration file is correct before startup. Syntax OK appears, indicating that there is no problem.

[root@aws php-5.6.30] # / usr/local/apache2.4/bin/apachectl-t

Syntax OK

8. The command to start httpd is as follows:

/ usr/local/apache2.4/bin/apachectl start

9. The command to see if it starts is as follows:

[root@aws srclib] # netstat-lnp | grep httpd

Tcp6 0 0: 80: * LISTEN 30298/httpd

10. Do a simple test, and the appearance of It works indicates that the test is successful

[root@aws srclib] # curl localhost

It works!
