下载Apache 2.4路径可参考：
http://httpd.apache.org/download.cgi
http://mirrors.cnnic.cn/apache//httpd/httpd-2.4.10.tar.gz
解决依赖关系的包 apr、apr-util、pcre
apr、apr-util下载路径可参考：
http://www.eu.apache.org/dist/apr/ 或https://mirrors.cnnic.cn/apache/apr/ 或http://apache.fayea.com/apache-mirror//apr/
pcre下载路径可参考：
http://softlayer-sng.dl.sourceforge.net/project/pcre/pcre/8.36/pcre-8.36.tar.gz
1、安装apr
[root@localhost Desktop]# cd /usr/local/src
[root@localhost src]# wget http://www.eu.apache.org/dist/apr/apr-1.6.3.tar.gz
[root@localhost src]# tar -zxvf apr-1.6.3.tar.gz
[root@localhost src]# cd apr-1.6.3
[root@localhost apr-1.6.3]# ./configure --prefix=/usr/local/apr
[root@localhost apr-1.6.3]# make
[root@localhost apr-1.6.3]# make install
[root@localhost apr-1.6.3]# cd ..2、安装apr-util
[root@localhost src]# wget http://mirrors.cnnic.cn/apache/apr/apr-util-1.6.1.tar.gz
[root@localhost src]# tar -zxvf apr-util-1.6.1.tar.gz
[root@localhost src]# cd apr-util-1.6.1
[root@localhost apr-util-1.6.1]# ./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr/bin/apr-1-config
[root@localhost apr-util-1.6.1]# make
[root@localhost apr-util-1.6.1]# make install
[root@localhost apr-util-1.6.1]# cd ..有时在make后会报错
make[1]: *** [xml/apr_xml.lo] Error 1
make[1]: Leaving directory `/usr/local/src/apr-util-1.6.0'
make: *** [all-recursive] Error 1大致是说缺少了 xml 的解析器。查阅网络资料后找到了解决方案，yum 安装一个 expat-devel 包即可：
yum -y install expat-devel3、正则表达式库安装
[root@localhost src]# wget http://ftp.exim.llorien.org/pcre/pcre-8.10.tar.gz
[root@localhost src]# tar -zxvf pcre-8.10.tar.gz
[root@localhost src]# cd pcre-8.10
[root@localhost pcre-8.10]# ./configure --prefix=/usr/local/pcre
[root@localhost pcre-8.10]# make
[root@localhost pcre-8.10]# make install有时make后会报错
./libtool: line 990: g++: command not found
make[1]: *** [pcrecpp.lo] Error 1
make[1]: Leaving directory `/usr/local/src/pcre-8.10'
make: *** [all] Error 2这个错误是缺少gcc安转包，运行如下命令：
yum -y install gcc-c++成功后在执行make，又报错：
libtool: link: Fatal configuration error.
make[1]: *** [libpcrecpp.la] Error 1
make[1]: Leaving directory `/usr/local/src/pcre-8.10'
make: *** [all] Error 2于是重新执行了一边./configure –prefix=/usr/local/pcre 后有执行make，第三次报错：
.libs/pcrecpp.o: could not read symbols: Bad value
collect2: ld returned 1 exit status
make[1]: *** [libpcrecpp.la] Error 1
make[1]: Leaving directory `/usr/local/src/pcre-8.10'
make: *** [all] Error 2在./configure后加上–disable-shared –with-pic ，执行后在执行make
./configure --prefix=/usr/local/pcre --disable-shared --with-pic
make 好了。。。。

安装apache2.2
[root@localhost src]# wget https://mirrors.cnnic.cn/apache//httpd/httpd-2.2.34.tar.gz --no-check-certificate
[root@localhost src]# tar -zxvf httpd-2.2.34.tar.gz
[root@localhost src]# cd httpd-2.2.34
[root@localhost httpd-2.2.34]# ./configure --prefix=/usr/local/apache2 --enable-deflate --enable-expires --enable-headers --enable-modules=most --enable-so --with-mpm=worker --enable-rewrite --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util --with-pcre=/usr/local/pcre
[root@localhost httpd-2.2.34]# make
[root@localhost httpd-2.2.34]# make install① ./configure时报错：
configure: error: Did not find pcre-config script at 到local下看了一下，没有prce，于是重新安装了一次prce，local下有了，然后安装apache，第二次报错：
checking for zlib location... not found
checking whether to enable mod_deflate... configure: error: mod_deflate has been requested but can not be built due to prerequisite failures网上搜索应该是没有zlib-devel，于是安装
yum install zlib-devel -y在执行./configure 成功了
② make install时又报错：
collect2: ld returned 1 exit status
make[2]: *** [htpasswd] Error 1
make[2]: Leaving directory `/usr/local/src/httpd-2.2.34/support'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/usr/local/src/httpd-2.2.34/support'
make: *** [all-recursive] Error 1make clean一下
apache的编译选项上增加 –libdir=/usr/lib64 即：
./configure --prefix=/usr/local/apache2 --enable-deflate --enable-expires --enable-headers --enable-modules=most --enable-so --with-mpm=worker --enable-rewrite --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util --with-pcre=/usr/local/pcre --libdir=/usr/lib64依旧是那个错，各种搜索之后发现一片文章总结的错误很好，
http://www.jianshu.com/p/ba5d5622e9d8，参照他第九个错误，重复了我这里2、安装apr-util的操作，然后就好了
5、启动apache：
/usr/local/apache2/bin/apachectl start安装apache2.4
环境与前面相同
[root@localhost src]# wget http://apache.cs.utah.edu//httpd/httpd-2.4.29.tar.gz --no-check-certificate
[root@localhost src]# tar -zxvf httpd-2.4.29.tar.gz
[root@localhost src]# cd httpd-2.4.29
[root@localhost httpd-2.4.29]# ./configure --prefix=/usr/local/apache2 --enable-rewrite --enable-so --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util --with-pcre=/usr/local/pcre --libdir=/usr/lib64
[root@localhost httpd-2.4.29]# make
[root@localhost httpd-2.4.29]# make install启动报错：
[root@localhost Desktop]# /usr/local/apache2/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
(98)Address already in use: AH00072: make_sock: could not bind to address [::]:80
(98)Address already in use: AH00072: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
AH00015: Unable to open logs进入apache的安装目录，编辑httpd.conf文件，搜索”#ServerName”，添加ServerName localhost:80
cd /usr/local/apache2/conf
vi httpd.conf
第二次启动又报错
(98)Address already in use: AH00072: make_sock: could not bind to address [::]:80
(98)Address already in use: AH00072: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
AH00015: Unable to open logs说明80端口被用
终端： ps -ef|grep httpd察看占用的进程或者用netstat -lnp|grep 80
找到后kill掉
[root@localhost conf]# ps -ef|grep httpd

root 55426 55402 0 07:48 pts/1 00:00:00 grep httpd
[root@localhost conf]# kill all httpd重启好了
yum安装apache：
[root@localhost Desktop]# rpm -qa httpd //先在系统上面查询一下是否已经安装了apache
[root@localhost Desktop]# yum install httpd -y //没有的话安装
[root@localhost Desktop]# rpm -qa httpd
httpd-2.2.15-29.el6.centos.x86_64
[root@localhost Desktop]# service httpd start //启动apache
Starting httpd: httpd: Could not reliably determine the server's fully qualified domain name, using localhost.localdomain for ServerName
