安装apache2.4.29
需要下载下列所示的几个源码包：
httpd-2.4.29.tar.gz
apr-1.6.3.tar.gz
apr-util-1.6.1.tar.gz
pcre-8.41.tar.gz
#安装apr
tar -zxvf apr-1.6.3.tar.gz
cd apr-1.6.3
./configure --prefix=/usr/local/apr && make -j 4 && make install
#安装apr-util
tar -zxvf apr-util-1.6.1.tar.gz
cd apr-util-1.6.1
./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr && make -j 4 && make install
#安装pcre2
tar -zxvf pcre-8.41.tar.gz
cd pcre-8.41
./configure --prefix=/usr/local/pcre && make -j 4 && make install
#安装apache24
tar -zxvf httpd-2.4.29.tar.gz
cd httpd-2.4.29
./configure --prefix=/home/apache2 --enable-cgi --enable-cgid --enable-ssl --enable-rewrite --with-pcre=/usr/local/pcre --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util --enable-modules=most --enable-mods-shared=most --enable-mpms-shared=all --with-mpm=event --with-mpm=event --enable-proxy --enable-proxy-fcgi --enable-expires --enable-deflate --enable-suexec --with-suexec-caller=daemon
make -j 4 && make install
#--enable-suexec 负责处理CGI和SSI程序的请求,确保网页使用者能以该目录或程序的用户ID来执行远程程序。
###############生成mod_jk连接tomcat###############
mod_jk下载地址为：http://tomcat.apache.org/download-connectors.cgi
tomcat-connectors-1.2.41-src.tar.gz
tar -zxvf tomcat-connectors-1.2.41-src.tar.gz
cd tomcat-connectors-1.2.41-src/native
./configure --with-apxs=/home/apache2/bin/apxs && make -j 4
apache-2.0文件夹下可以找到mod_jk.so。将这个文件复制到apache安装路径下的modules文件夹下

安装编译过程中第一个错xml/apr_xml.c:35:19: error: expat.h: No such file or directory
参考:Linux 编译 apr-util 时报错 - mingc - 博客园 https://www.cnblogs.com/mingc/p/7695610.html
应安装:yum -y install expat-devel
重新编译./configure make. make install..三部曲
+++++++make
安装编译过程中第二个错make[2]: *** [htpasswd] Error 1
参考:APACHE 编译错误：make[2]: *** [htpasswd] Error 1 解决办法-kennyluo-51CTO博客 http://blog.51cto.com/uppower/1123033
解决办法
#mv /usr/lib/libm.a /usr/lib/libm.a.bak
#mv /usr/lib/libm.so /usr/lib/libm.so.bak
#mv /usr/lib/libexpat.so /usr/lib/libexpat.so.bak
#ln -s /usr/lib64/libm.a /usr/lib/libm.a
#ln -s /usr/lib64/libm.so /usr/lib/libm.so
#ln -s /usr/lib64/libexpat.so /usr/lib/libexpat.so
然后这个解决不了。有说是apr版本过高建议换成[1.5版本](http://archive.apache.org/dist/apr/)
++++++++make
make时出现server/.libs/libmain.a(exports.o):(.data+0xcfc): undefined reference to `apr_os_uuid_get’，
解决办法：
cd srclib/apr; make
cd srclib/apr-util; make
++++++++start启动报错
AH00534: httpd: Configuration error: No MPM loaded.
配置文件httpd.conf，启用此模块
LoadModule mpm_event_module modules/mod_mpm_event.so
