Ubuntu 16.04 source compilation and installation of Apache 2.4.25 tutorial

This article introduced the Ubuntu 16.04 source code compilation and installation of Apache, for your reference, the specific content is as follows

apache installation guide: http: / / httpd apache. org docs / 2.4 / install html

The installation guide provides detailed instructions for the installation process, but here are just a few caveats:

1. To compile and install apache, some dependent environments must be installed, otherwise the following compilation will report that the corresponding multiple files cannot be found:

APR (Apache portable Run - time libraries, Apache portable runtime) and APR - Util,, can see apr http: / / www cnblogs. com/iLumia p / 4214886 html download address: http: / / apr apache. org /

PCRE library if not install pcre, please download: http: / / www pcre. org
In addition, there are some disk space requirements, C compiler, time synchronization, Perl5 can be adjusted as needed.

2. Next are the detailed installation steps:
Here I'm used to putting the source code under /usr/local/src, switching directories according to my habit.

1). Install apr-1.5.2
Switch to the source directory of apr

cd /usr/local/src/apr-1.5.2/

Installation and compilation

./configure --prefix=/usr/local/apache/apr
make -j4( X according to the audit number of your computer 2 To set the parallel compilation parameters to improve the compilation speed )
sudo make install

2). Install apr-util-1.5.4

Switch to the source directory of apr-util

cd /usr/local/src/apr-util-1.5.4/

Installation and compilation

./configure --prefix=/usr/local/apache/apr-util --with-apr=/usr/local/apache/apr
make -j4
make install

3). Install pcre-8.39

Go to the installation directory

cd /usr/local/src/pcre-8.39/

Installation and compilation

./configure --prefix=/usr/local/pcre
make -j4
make install

4. After installing the dependencies, you can install apache
Enter the apache source directory

cd /usr/local/src/httpd-2.4.25/

Installation and compilation

We need to specify the location of the dependent package we just installed with the wounwith parameter

./configure --prefix=/usr/local/apache --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util/ --with-pcre=/usr/local/pcre
make -j4
make install

At this point, we have completed the source installation of apache, and now we are ready to serve apache
Add startup script:

cp /usr/local/apache/bin/apachectl /etc/init.d/httpd

Add environment variables:

echo 'export PATH=$PATH:/usr/local/apache/bin' > /etc/profile.d/httpd.sh
chmod a+x /etc/profile.d/httpd.sh
source /etc/profile.d/httpd.sh

You can then manage httpd in a variety of ways. If you need to boot yourself up, just add the startup command to /etc/ rc.local.

sudo /usr/local/apache/bin/apachectl start

An error may be reported that the port is occupied and the httpd.conf file needs to be modified

sudo gedit /usr/local/apache/httpd/conf/httpd.conf

Then change the ServerName line to ServerName 127.0.0.1:80

Change Listen line 80 to Listen line 127.0.0.1:80

Then save and start the apache service.

service httpd start

Note:
If the profile cannot be found when starting the service, one way is to copy one profile to the corresponding path,
Or when you start apache, add the -f parameter to indicate the absolute path to the profile.
