本文档解决AppacheHttp由版本2.2.x升级到版本2.4.29的问题，安装需要先进行依赖软件包的安装，请检查相应依赖软件包安装情况，如系统已经正确安装相应依赖软件包，可略过，本文所述版本升级不会覆盖先前的apache服务器
1. 安装包准备
将上述所有源码包上传到/tmp目录下,并用root用户登陆
2. 安装expat-2.1.0
cd /tmp
tar -zxvf expat-2.1.0.tar.gz
cd expat-2.1.0
./configure
make && make install
3. 安装apr-1.6.3.tar.gz
cd /tmp
tar -zxvf apr-1.6.3.tar.gz
cd apr-1.6.3
./configure --prefix=/usr/local/apr
make && make install
4. 安装apr-util-1.5.4
cd /tmp
tar -jxvf apr-util-1.5.4.tar.bz2
cd apr-util-1.5.4
./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr
make && make install
5. 安装pcre-8.41
cd /tmp
tar -zxvf pcre-8.41.tar.gz
cd pcre-8.41
./configure --prefix=/usr/local/pcre
make && make install
6. 安装httpd-2.4.29
cd /tmp
tar -zxvf httpd-2.4.29.tar.gz
cp -rf apr-1.6.3 httpd-2.4.29/srclib/apr
cp -rf apr-util-1.5.4 httpd-2.4.29/srclib/apr-util
cd httpd-2.4.29
./configure --prefix=/opt/apache2 --enable-mods-shared=all --enable-deflate --enable-speling --enable-cache --enable-file-cache --enable-disk-cache --enable-mem-cache --enable-rewrite --enable-so --with-apr=/usr/local/apr/ --with-apr-util=/usr/local/apr-util/ --with-pcre=/usr/local/pcre --with-included-apr
make && make install
注意：
可能出现的错误：make时出现server/.libs/libmain.a(exports.o):(.data+0xcfc): undefined reference to `apr_os_uuid_get’，解决办法：
cd /tmp/ httpd-2.4.29
cd srclib/apr;
make
cd ..
cd srclib/apr-util;
make
再退回 apache 的源码目录重新 make
cd /tmp/ httpd-2.4.29
make && make install
如想再安装一个更新的apache服务，使用
./configure --prefix=/opt/apache3 --enable-mods-shared=all --enable-deflate --enable-speling --enable-cache --enable-file-cache --enable-disk-cache --enable-mem-cache --enable-rewrite --enable-so --with-apr=/usr/local/apr/ --with-apr-util=/usr/local/apr-util/ --with-pcre=/usr/local/pcre --with-included-apr --enable-ssl
其它命令不变，只是--prefix=路径 改变即可
7. 修改配置文件
cd /opt/apahce2/conf
vi httpd.conf
ServerName 配置为127.0.0.1:80
Include conf/extra/httpd-info.conf 这一行前的#去掉
以上为测试配置
如果想把两个老apache迁移过来，请参考原来配置文件，将配置文件中的配置信息（见备注）覆盖过来
8. 重新启动apache
#ps -ef | grep apache
#kill -9 进程名（如果有进程）
启动新安装的apache服务
/opt/apache2/bin/httpd -k start -f /opt/apache2/conf/httpd.conf
9. 验证
在浏览器中输入:http://服务器ip出现下图说明正常
备注:
原apacheHttpdServer安装路径为/opt/apahce和/opt/apache1
更新的apacheHttpdServer安装路径/opt/apache2
配置文件路径/opt/apache2/conf/httpd.conf
页面部署路径/opt/apache2/htdocs
停止服务：/opt/apache2/bin/httpd -k stop -f /opt/apache2/conf/httpd.conf（或 /opt/apache2/bin/apachectl start）
开启服务：/opt/apache2/bin/httpd -k start -f /opt/apache2/conf/httpd.conf（或 /opt/apache2/bin/apachectl stop）
如需安装两个新服务，第二个路径可设置在/opt/apache3，当要进行 make clean一下，否则出错，安装过程等同/opt/apache2的操作。
老版本apahce配置信息备份：
