3、安装Apache
1)检查是否安装与否；
rpm -qa httpd
2)下载及安装
wget --no-check-certificate ‘www-us.apache.org/dist/httpd/…’
[root@jackroo tools]# ls httpd-2.2.27.tar.gz -sh #sh查看大小
7.2M httpd-2.2.27.tar.gz
tar xf httpd-2.2.27.tar.gz #解压
安装
./configure
–prefix=/application/apache2.2.27
–enable-expires
–enable-headers
–enable-modules=most
–enable-so
–with-mpm=worker
–enable-deflate
–enable-rewrite \
报错如下：
checking for zlib location… not found
checking whether to enable mod_deflate… configure: error: mod_deflate has been requeste
d but can not be built due to prerequisite failures
解决：
yum install zlib zlib-devel -y
接着安装
make
make install

启动失败问题排查：
/application/apache/htdocs
#htdocs目录下修改index.html进行测试。

6、扩展的配置文件
/application/apache/conf/extra
[root@jackroo extra]# ls

httpd-dav.conf httpd-manual.conf httpd-userdir.conf
httpd-default.conf httpd-mpm.conf httpd-vhosts.conf
httpd-info.conf httpd-multilang-errordoc.conf

2)[root@jackroo extra]# vim httpd-mpm.conf
3)[root@jackroo extra]# cat httpd-default.conf
