我们需要先下载三个源码包
wget http://httpd.apache.org/download.cgi/httpd-2.4.37.tar.gz wget http://archive.apache.org/dist/apr/apr-1.5.0.tar.gz wget http://archive.apache.org/dist/apr/apr-util-1.5.4.tar.gz
然后安装编译时需要用到的环境
yum install -y gcc gcc-c++ cmake
解压http源码包
tar -zxvf httpd-2.4.37.tar.gz
如果出现以下错误
[root@localhost httpd-2.4.37]# ./configure --prefix=/usr/local/apache24 checking for chosen layout... Apache checking for working mkdir -p... yes checking for grep that handles long lines and -e... /usr/bin/grep checking for egrep... /usr/bin/grep -E checking build system type... x86_64-pc-linux-gnu checking host system type... x86_64-pc-linux-gnu checking target system type... x86_64-pc-linux-gnu configure: configure: Configuring Apache Portable Runtime library... configure: checking for APR... no configure: error: APR not found. Please read the documentation.
需要先安装apr
[root@localhost aprl-1.5.0]tar -zxvf apr-1.5.0.tar.gz
进入apr-1.5.0目录
./configure --prefix=/usr/local/apr/ make&&make install
解压apr-util
tar -zxvf apr-util-1.5.4.tar.gz cd apr-util-1.5.4
配置apr-util
[root@localhost apr-util-1.5.4]# ./configure --prefix=/usr/local/apr-util/ checking build system type... x86_64-unknown-linux-gnu checking host system type... x86_64-unknown-linux-gnu checking target system type... x86_64-unknown-linux-gnu checking for a BSD-compatible install... /usr/bin/install -c checking for working mkdir -p... yes APR-util Version: 1.5.4 checking for chosen layout... apr-util checking for gcc... gcc checking whether the C compiler works... yes checking for C compiler default output file name... a.out checking for suffix of executables... checking whether we are cross compiling... no checking for suffix of object files... o checking whether we are using the GNU C compiler... yes checking whether gcc accepts -g... yes checking for gcc option to accept ISO C89... none needed Applying apr-util hints file rules for x86_64-unknown-linux-gnu checking for APR... no configure: error: APR could not be located. Please use the --with-apr option.
报错了我们就按照错误指示重新配置
./configure --prefix=/usr/local/apr-util/ --with-apr=/usr/local/apr/ make && make install
切换到http源的文件下
./configure --prefix=/usr/local/apache24/ --with-apr=/usr/local/apr/ --with-apr-util=/usr/local/apr-util/
又有新的错误
configure: error: pcre-config for libpcre not found. PCRE is required and available from http://pcre.org / 下载pcre源码包
wget https://ftp.pcre.org/pub/pcre/pcre-8.42.tar.gz tar -zxvf pcre-8.42.tar.gz cd pcre-8.42/ ./configure --prefix=/usr/local/pcre/ make && make install
切换到http目录下
./configure --prefix=/usr/local/apache24/ --with-apr=/usr/local/apr/ --with-apr-util=/usr/local/apr-util/ --with-pcre=/usr/local/pcre/
make && make install
关闭防火墙
[root@localhost httpd-2.4.37]# systemctl stop firewalld.service [root@localhost httpd-2.4.37]# systemctl disable firewalld.service Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service. Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
启动apache服务
cd /usr/local/apache24/bin/
[root@localhost bin]# ./apachectl start AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using localhost.localdomain. Set the 'ServerName' directive globally to suppress this message
但是当我们查看端口时显示80已经启动了
[root@localhost bin]# netstat -napt Active Internet connections (servers and established) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name

tcp6 0 0 :::22 :::* LISTEN 1020/sshd
tcp6 0 0 ::1:25 :::* LISTEN 1199/master
原因是服务器不能完全确认域名 解决方法：
vi /usr/local/apache24/conf/http.conf
把ServerName localhost:80前面的#去掉，保存退出即可。
杀死httpd进程，发现杀不死，于是重启虚拟机，开机后查看进程发现httpd没有启动
再次启动httpd进程的时候就不会出现不能确认域名的信息了。got it！
（后来发现用ps -aux查看http进程号，kill -9 进程id就可以成功杀死）
