1. Deployment Environment
1. System Version and Kernel

[root@localhost ~]# cat /etc/centos-release   CentOS release 6.9 (Final)  [root@localhost ~]# uname -r  2.6.32-696.el6.x86_64

2. Set the program package required for httpd installation to "Development tools" and "Server Platform Development". Use yum to install it.

[root@localhost ~]# yum groupinstall "Development tools" "Server Platform Development" -y

2. Compile and install the software package httpd2.4 on which http2.4 depends on apr, apr-util, and pcre of a later version. install these three software packages before installing httpd2.4. 1.compile and install apr-1.6.2.tar.gz.

[root@localhost ~]# wget http://mirrors.shuosc.org/apache/apr/apr-1.6.2.tar.gz[root@localhost ~]# tar xf apr-1.6.2.tar.gz -C /usr/local/src/[root@localhost ~]# cd /usr/local/src/apr-1.6.2/[root@localhost apr-1.6.2]# ./configure --prefix=/usr/local/apr[root@localhost apr-1.6.2]# make && make install

2.compile and install apr-util-1.6.0.tar.gz

[root@localhost ~]# wget http://mirrors.shuosc.org/apache/apr/apr-util-1.6.0.tar.gz[root@localhost ~]# tar xf apr-util-1.6.0.tar.gz -C /usr/local/src/[root@localhost ~]# cd /usr/local/src/apr-util-1.6.0/[root@localhost apr-util-1.6.0]# ./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr[root@localhost apr-util-1.6.0]# make && make install

3.compile and install pcre-8.41.tar.gz

[root@localhost ~]# wget https://ftp.pcre.org/pub/pcre/pcre-8.41.tar.gz[root@localhost ~]# tar xf pcre-8.41.tar.gz -C /usr/local/src/[root@localhost ~]# cd /usr/local/src/pcre-8.41/[root@localhost pcre-8.41]# ./configure --prefix=/usr/local/pcre[root@localhost pcre-8.41]# make && make install

Create apache users and groups first

[root@localhost ~]# groupadd -r apache[root@localhost ~]# useradd -r -g apache apache

Compile and install apache2.4

[root@localhost ~]# wget http://mirrors.shuosc.org/apache/httpd/httpd-2.4.28.tar.gz[root@localhost ~]# tar xf httpd-2.4.28.tar.gz -C /usr/local/src/[root@localhost ~]# cd /usr/local/src/httpd-2.4.28/[root@localhost httpd-2.4.28]# ./configure --prefix=/usr/local/apache2 --sysconf=/etc/httpd24 \> --with-included-apr --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util --with-pcre=/usr/local/pcre \> --enable-so --enable-ssl --enable-cgi --enable-rewrite --enable-modules=most --enable-mpms-shared=all --with-mpm=prefork

The meanings of the preceding options are as follows: -prefix =/usr/local/apache2 installation path-sysconf =/etc/httpd24 configuration file path-with-supported ded-apr contains apr-with-apr =/usr/local/apr specify the installation path of apr-with-apr-util =/usr/local/apr-util/Specify the installation path of apr-util-with-pcre =/usr/local/pcre pcre installation path-enable-so allows loading DSO module-enable-ssl at runtime. If not loaded, you cannot use https-enable-cgi to allow Using cgi script-enable-rewrite to support URLs. rewrite mechanism-enable-modules = most enable most common modules-enable-mpms-shared = all enable all modes supported by MPM-with-mpm = prefork by default prefork Mode

[root@localhost httpd-2.4.28]# make && make install

Note: configure: error: Bundled APR requested but not found. /srclib /. download and unpack the corresponding apr and apr-util packages. /srclib /. download the apr and apr-util source code, decompress the package to the httpd-2.4.28/srclib, and remove the version number.

[root@localhost httpd-2.4.28]# cp -rf /usr/local/src/apr-1.6.2 /usr/local/src/httpd-2.4.28/srclib/apr[root@localhost httpd-2.4.28]# cp -rf /usr/local/src/apr-util-1.6.0 /usr/local/src/httpd-2.4.28/srclib/apr-util

Run the command again.

Iv. Configuration after installation 1. Export the binary program directory to the path environment variable

[root@localhost ~]# vim /etc/profile.d/apache2.sh  export PATH=/usr/local/apache2/bin:$PATH  [root@localhost ~]# source /etc/profile.d/apache2.sh  [root@localhost ~]# echo $PATH  /usr/local/apache2/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin 

2. Export the outbound file path

[root@localhost ~]# vim /etc/ld.so.conf.d/apache2.conf  /usr/local/apache2/lib  [root@localhost ~]# ldconfig 

3. Export the header file, which can be link-based.

[root@localhost ~]# ln -sv /usr/local/apache2/include/ /usr/include/apache2   `/usr/include/apache2/include' -> `/usr/local/apache2/include/' 

4. Export help manual

[root@localhost ~]# vim /etc/man.config   MANPATH /usr/local/apache2/man  [root@localhost ~]# man -M /usr/local/apache2/man httpd

5. Start and test the apache service.

[root@localhost ~]# apachectl start  [root@localhost ~]# ss -tunl | grep 80  tcp    LISTEN    0    128        :::80        :::*   [root@localhost ~]# vim /etc/sysconfig/iptables  -A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT  [root@localhost ~]# service iptables restart

Open the browser and enter the IP address of the centos host in the browser. The page displays the following information:It works! Indicates that the apache service has been started normally. Note: during startup, "AH00558: httpd: cocould not reliably determine the server's fully qualified domain name, using localhost. localdomain. set the 'servername' directive globally to suppress this message "error. the solution is as follows:

[root@localhost ~]# vim /etc/httpd24/httpd.conf ServerName localhost:80 [root@localhost ~]# apachectl restart 

This error does not occur after the apache service is restarted. 6. Create an apache STARTUP script.

[root@localhost ~]# apachectl stop [root@localhost ~]# vim /etc/init.d/httpd 

#!/bin/bash # # httpd Startup script for the Apache HTTP Server # # chkconfig: - 85 15 # description: The Apache HTTP Server is an efficient and extensible \ # server implementing the current HTTP standards. # processname: httpd # config: /etc/httpd/conf/httpd.conf # config: /etc/sysconfig/httpd # pidfile: /var/run/httpd/httpd.pid # ### BEGIN INIT INFO # Provides: httpd # Required-Start: $local_fs $remote_fs $network $named # Required-Stop: $local_fs $remote_fs $network # Should-Start: distcache # Short-Description: start and stop Apache HTTP Server # Description: The Apache HTTP Server is an extensible server # implementing the current HTTP standards. ### END INIT INFO # Source function library. . /etc/rc.d/init.d/functions if [ -f /etc/sysconfig/httpd ]; then . /etc/sysconfig/httpd fi # Start httpd in the C locale by default.

Add the execution permission to the httpd File

[root@localhost ~]# chmod +x /etc/init.d/httpd 

Then you can use the service command to start and close httpd.

[root@localhost ~]# service httpd start [root@localhost ~]# service httpd restart [root@localhost ~]# service httpd stop 

7. Add auto-start upon startup

[root@localhost ~]# chkconfig --add httpd [root@localhost ~]# chkconfig httpd on [root@localhost ~]# chkconfig --list httpd httpd 0:off 1:off 2:on 3:on 4:on 5:on 6:off
