First, the source code is compiled and installed (the installation directory is in /home/xpy/tools/, ie cd /home/xpy/tools/) ----------- install gcc

1. First download the httpd service package, you need to use the wget command, if wget is not installed, then yum -y install wget

wget http://mirrors.shu.edu.cn/apache/httpd/httpd-2.4.37.tar.gz

2. Unzip httpd-2.4.37.tar.gz

tar zxvf httpd-2.4.37.tar.gz

3. Enter cd httpd-2.4.37

4. Start the installation

1) Test the installation to see if any packages are missing

./configure

The above is missing apr (portable operating environment) and apr-util

2) Download apr (portable operating environment) and apr-util

wget http://mirrors.shu.edu.cn/apache/apr/apr-1.6.5.tar.gz

wget http://mirrors.shu.edu.cn/apache/apr/apr-util-1.6.1.tar.gz

3) Unzip and install apr and apr-util separately

tar -zxvf apr-1.6.5.tar.gz

tar -zxvf apr-util-1.6.1.tar.gz

4) Switch to installation under apr-1.6.5

cd apr-1.6.5

./configure \
> --prefix=/application/apr-1.6.5

make &make install

5) Switch to installation under apr-util-1.6.1

cd apr-util-1.6.1

 ./configure \
> --prefix=/application/apr-util-1.6.1/ --with-apr=/application/apr-1.6.5/

At this time, an error will be reported

Need to install another service, yum install expat-devel

If it is not installed by the root user, an error will be reported

At this time, switch to the root user

make & make install

6) When both apr and apr-util are installed, return to install apache

cd /home/xpy/tools/httpd-2.4.37

Try to install ./configure and find an error

This is the lack of pcre package, need to reinstall

7) Install the pcre package (cd /home/xpy/tools/), remember not to download pcre2

Download package wget https://ftp.pcre.org/pub/pcre/pcre-8.42.tar.gz

Unzip tar -zxvfpcre-8.42.tar.gz

cd pcre-8.42.tar.gz

./configure \

--prefix=/application/pcre-8.42

At this time, an error will be reported again, prompting configure: error: You need a C++ compiler for C++ support.

At this time, an environmental tool needs to be installed

yum groupinstall "Development Tools"

After the installation is complete, reinstall pcre

./configure \

--prefix=/application/pcre-8.42

make & make install

8) Install apache (sentence knocking)

./configure \

--prefix=/application/apache2.4.37 \

--with-apr=/application/apr-1.6.5 \

--with-apr-util=/application/apr-util-1.6.1 \

--with-pcre=/application//pcre-8.42 \

--enable-deflate \

--enable-expires \

--enable-headers \

--enable-modules=most \

--enable-so \

--with-mpm=worker \

--enable-rewrite

But it will report an error, suggesting checking whether to enable mod_deflate... configure: error: mod_deflate has been requested but can not be built due to prerequisite failures

This is the reason why zlib-devel is not installed

yum install zlib-devel

Repeat the ./configure action again

make

make install

The installation is complete (check if there is an error echo $?)

9) Create a soft connection

ln -s /application/apache2.4.37/   /application/apache

10) Start the apache service

 /application/apache2.4.37/bin/httpd -k start

11) Check if the port is up

lsof -i :80

12) Check if the process is up

ps -ef | grep httpd

13) See if it works

View ip

ifconfig eth0

Enter this address in the URL
