安装httpd
http://httpd.apache.org/download.cgi
httpd-2.4.29.tar.gz
#创建httpd用户
groupadd httpd
useradd -g httpd -s /sbin/nologin -M httpd
tar zxvf httpd-2.4.29.tar.gz
cd httpd-2.4.29
./configure --prefix =/usr/local/apache
make && make install
编译apache时可能会出错：
#./configure --prefix……检查编辑环境时出现：
checking for APR… no
configure: error: APR not found . Please read the documentation
解决办法：
安装 apr apr-util pcre
https://apr.apache.org/download.cgi
apr-1.6.3.tar.gz
./configure --prefix=/usr/local/apr
make && make install
apr-util-1.6.1.tar.gz
./configure --prefix=/usr/local/apr-util -with-apr=/usr/local/apr/bin/apr-1-config
make && make install
编译apr-util时报错：make[1]: *** [xml/apr_xml.lo] Error 1
解决方法：yum -y install expat-devel
ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/
pcre-8.38.zip
./configure --prefix=/usr/local/pcre
make && make install
然后安装Apache：
./configure --prefix=/usr/local/apache/ --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util/ --with-pcre=/usr/local/pcre/
make && make install

make 时上面报错，尝试用 apr-1.5.2 版本
下载地址： http://archive.apache.org/dist/apr/
wget http://archive.apache.org/dist/apr/apr-1.5.2.tar.gz
wget http://archive.apache.org/dist/apr/apr-util-1.5.2.tar.gz
安装方法与上面 1.6版本一样，果然成功了。应该是 CentOS7 才支持 apr-1.6 版本。
安装完成后，切到安装目录，/usr/local/apache
#vim conf/httpd.conf
#配置 “Listen” 和“ServerName”属性
Listen 80
ServerName localhost
#./bin/apachectl configtest
Syntax OK
#启动httpd
/usr/local/apache/bin/apachectl start | stop | restart
或者：
cp /usr/local/apache/bin/apachectl /etc/init.d/httpd
/etc/init.d/httpd start
验证访问：
http://“server ip”
It works!
报错总结及处理方法：
（1）configure: error: APR not found. Please read the documentation.
这是没有安装apr或者apr安装失败导致的，重新安装apr。
安装请查看第一步。
（2）configure: error: APR-util not found. Please read the documentation.

yum install -y gcc
（4）xml/apr_xml.c:35:19: 致命错误：expat.h：没有那个文件或目录
这是没有安装expat-devel或者expat-devel安装失败导致的，重新安装expat-devel。
yum install -y expat-devel
（5）configure: error: Invalid C++ compiler or C++ compiler flags
这是没有安装gcc-c++或者gcc-c++安装失败导致的，重新安装gcc-c++。
yum install -y gcc-c++
（6）configure: error: pcre-config for libpcre not found. PCRE is required and available from http://pcre.org/
