        configure: error: APR not found.  Please read the documentation.     

5.解决 configure: error: APR not found.  Please read the documentation. 
        1.下载 APR  http://apr.apache.org/download.cgi
        2.解压到 /usr/local/src
        3../configure --prefix=/usr/local/apr
        4.make
        5.make install 

6.再次执行 ./configure --prefix=/usr/local/apache2 
[root@gaocun httpd-2.4.48]# ./configure --prefix=/usr/local/apache2
        checking for chosen layout... Apache
        checking for working mkdir -p... yes

        configure: 
        checking for APR-util... no
        configure: error: APR-util not found.  Please read the documentation.

7.解决 configure: error: APR-util not found.  Please read the documentation.
        1.下载 APR-util  http://apr.apache.org/download.cgi
        2.解压到 /usr/local/src  
                [root@gaocun src]# tar -zxvf apr-util-1.6.1.tar.gz 

                gzip: stdin: not in gzip format
                tar: Child returned status 1
                tar: Error is not recoverable: exiting now
        原因:这个Tarball没有经过zip压缩,所以不用使用-z来解压

        3../configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr/bin/apr-1-config
        4.make 
                编译时报错:
                xml/apr_xml.c:35:19: 致命错误：expat.h：没有那个文件或目录
                 #include <expat.h>
                                   ^
                编译中断。
                make[1]: *** [xml/apr_xml.lo] 错误 1
                原因:缺少<expat.h>包
                解决:yum install expat-devel
        5.make install 

8.再次执行 ./configure --prefix=/usr/local/apache2 
        报错
                configure: 
                checking for APR-util... no
                configure: error: APR-util not found.  Please read the documentation.
        原因:手动指定 apr和apr-util的路径
        ./configure --prefix=/usr/local/apache2  --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util --with-pcre=/usr/local/pcre
               报错：
                    checking for pcre-config... false
                    configure: error: pcre-config for libpcre not found. PCRE is required and available from http://pcre.org/
                原因：未找到pcre
                1.下载 https://sourceforge.net/projects/pcre/
                2.解压到/usr/local/src
                3.生成Makefile  ./configure --prefix=/usr/local/pcre
                        报错:configure: error: Invalid C++ compiler or C++ compiler flags
                        原因:缺少gcc-c++ 库
                        解决: yum install -y gcc-c++
                4.make
                5.make install

9.再次执行 ./configure --prefix=/usr/local/apache2  --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util --with-pcre=/usr/local/pcre

        configure: summary of build options:

11.make install 


正确编译apache2
1.下载 httpd https://mirrors.bfsu.edu.cn/apache//httpd/httpd-2.4.48.tar.bz
2.下载依赖软件 APR https://apache.claz.org//apr/apr-1.7.0.tar.gz
3.下载依赖软件 APR-util https://apache.claz.org//apr/apr-util-1.6.1.tar.gz
4.下载依赖软件 pcre https://sourceforge.net/projects/pcre/files/latest/download
5.下载<expat.h> 编译APR-util需要 yum install expat-devel

7.将httpd-2.4.48.tar.bz 解压到/usr/local/src 
8.将apr-1.7.0.tar.gz 解压到 httpd-2.4.48/srclib 下,命名为apr
9.将apr-util-1.6.1.tar.gz 解压到httpd-2.4.48/srclib 下,命名为apr-util
10.生成Makefile 
        ./configure \
        --prefix=/usr/local/apache2/ \
        --with-pcre=/usr/local/pcre/ \
        --with-included-apr
11.编译 make
12.安装 make install 

13.启动
./apachectl -f /usr/local/apache2/conf/httpd.conf -k start
        报错:[Mon Aug 02 14:40:56.986318 2021] [core:notice] [pid 9066:tid 139880478857024] AH00094: Command line: '/usr/local/apache2//bin/httpd -f /usr/local/apache2/conf/httpd.conf'
