1. Download the packages installed by Apache
https://mirrors.aliyun.com/apache/httpd/httpd-2.4.38.tar.bz2
Unzip tar zxf httpd-2.4.38.tar.bz2 -C / opt
http://apache.fayea.com/apr/apr-1.6.5.tar.gz
Unzip tar zxf apr-1.6.5.tar.gz -C / opt
http://apache.fayea.com/apr/apr-util-1.6.1.tar.gz
Unzip tar zxf apr-util-1.6.1.tar.gz -C / opt
http://ftp.pcre.org/pub/pcre/pcre-8.00.tar.gz
Unzip tar zxf pcre-8.00.tar.gz -C / opt
Note that the apr installation package version is the same or lower than the apr-util installation package version.
2. The environment required to install Apache
yum install gcc gcc-c++ make -y
3. Create the installation directory
The installation directory is placed under / usr / local and established as follows
mkdir apr
mkdir apr-util
mkdir pcre
mkdir apache
4. Install apr
cd /usr/local/apr
1. Establish an installation inspection environment
./configure --prefix = / usr / local / apr (specify installation directory)
Generate a makefile compilation file
With echo $ ?, you can check whether the command is executed successfully. If it is 0, it succeeds, otherwise it fails.
2. Compile
make
Function: Compile the source code package into machine code, the compilation fails, make clean clears the previous compilation cache, and resolves the dependencies before making.
Use echo $? to see if it is successful
3. Installation
make install
Use echo $? to see if it is successful
5. Install apr-util
cd /usr/local/apr-util
1. Establish an installation inspection environment
./configure --prefix = / usr / local / apr-util (specify the installation directory) –with-apr = / usr / local / apr / bin / apr-1-config ( Establish a dependency relationship with apr)
Use echo $? to see if the execution is successful
2. Compile
make
Function: Compile the source code package into machine code, the compilation fails, make clean clears the previous compilation cache, and resolves the dependencies before making.
Use echo $? to see if it is successful
Possible error installation yum install expat-devel -y
3. Installation
make install
Use echo $? to see if it is successful
6. Install pcre
cd /usr/local/pcre
1. Establish an installation inspection environment
./configure --prefix = / usr / local / pcre (specify installation directory)
Use echo $? to see if the execution is successful
2. Compile
make
Function: Compile the source code package into machine code, the compilation fails, make clean clears the previous compilation cache, and resolves the dependencies before making.
Use echo $? to see if it is successful
3. Installation
make install
Use echo $? to see if it is successful
7. Install apache
cd /usr/local/apache
1. Establish an installation inspection environment
./configure --prefix=/usr/local/apache/ --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util/ --with-pcre=/usr/local/pcre/
Use echo $? to see if the execution is successful
2. Compile
make
Function: Compile the source code package into machine code, the compilation fails, make clean clears the previous compilation cache, and resolves the dependencies before making
Use echo $? to see if it is successful
3. Installation
make install
Use echo $? to see if it is successful
8. Start Apache
1. Turn off the firewall
systemctl stop firewalld
2. Close the kernel firewall
setenforce 0
3. Start apache (start Apache with an absolute path)
/usr/local/apache/bin/apachectl start
4. View the progress
ps -ef |grep httpd

This will start Apache.
9. Set to start automatically
1. Add startup service
cp /usr/local/apache/bin/apachectl /etc/rc.d/init.d/httpd
chkconfig --add httpd
2. Run systemctl stop httpd

This situation may occur. It only needs to execute systemctl daemon-reload (reload of background program) to solve
there will be no problems during execution
