搭建Apache服务

第一种方法（centos、Redhat）yum安装：
一、用yum安装Apache服务
yum install -y http*

二、启动Apache服务
systemctl start httpd

三、查看Apache服务端口号和进程
netstat -anptu|grep http
ps -aux |grep http

四、直接在浏览器输入ip地址访问
http://ip地址

备注：
Apache配置文件
/etc/httpd/conf/httpd.conf
网页配置文件
/etc/httpd/conf.d/welcome.conf
网页文件
/usr/share/httpd/noindex/index.html

修改网页文件改成本身制做的网页
网页配置文件能够改网页文件路径

第二种方法（ubuntu、centos、Redhat）编译安装：
apache 安装指南：http://httpd.apache.org/docs/2.4/install.html
编译安装说明：
在编译安装apache时，首先要先安装Apache依赖环境
即
ubuntu@ubuntu:~$ ls
apr-1.6.3.tar.gz apr-util-1.6.1 apr-util-1.6.1.tar.gz pcre-8.39 pcre-8.39.tar.gz

1.编译安装apache有些依赖环境必须安装，否则后面编译会报找不到相应多文件：

APR(Apache portable Run-time libraries，Apache可移植运行库)和APR-Util，apr介绍能够参见：http://www.cnblogs.com/iLumia/p/4214886.html
下载地址：http://apr.apache.org/

PCRE库 若是没有安装过pcre的话，请先下载：https://sourceforge.net/projects/pcre/files/pcre/8.39/pcre-8.39.tar.gz/download
除此以外，还有些磁盘空间要求，C编译器，时间同步，Perl5 能够根据须要，自行调整便可。

2.安装apr
ubuntu@ubuntu:~$ cd apr-1.6.3/ #进入下载的apr目录下
./configure --prefix=/usr/local/apache/apr #指定安装目录

make -j4(根据本身电脑核数×2来设定并行编译参数，提升编译速度)

sudo make install

3.安装apr-util
ubuntu@ubuntu:~$ cd apr-util-1.6.1/ #进入下载的apr-util目录下
./configure --prefix=/usr/local/apache/apr-util --with-apr=/usr/local/apache/apr #指定安装目录和apr

make -j4

make install

4.安装pcre
ubuntu@ubuntu:~$ cd pcre-8.39/ #进入下载的pcre目录下
./configure --prefix=/usr/local/pcre #指定安装目录

make -j4

make install

5.安装好依赖环境就能够开始安装Apache
ubuntu@ubuntu:~$ cd httpd-2.4.33/ #进入下载的apache目录下
./configure --prefix=/usr/local/apache --with-apr=/usr/local/apache/apr --with-apr-util=/usr/local/apache/apr-util/ --with-pcre=/usr/local/pcre

make -j4

make install

到此Apache编译安装结束

6.添加启动脚本
cp /usr/local/apache/bin/apachectl /etc/init.d/httpd

7.添加环境变量
echo 'export PATH=$PATH:/usr/local/apache/bin' > /etc/profile.d/httpd.sh

chmod 777 /etc/profile.d/httpd.sh

source /etc/profile.d/httpd.sh

备注：以后就能够多种方式管理httpd了，若是须要开机自启，将启动命令添加到/etc/rc.local 中便可。

注意：
sudo /usr/local/apache/bin/apachectl start

可能会报错说端口被占用，须要修改httpd.conf文件

sudo vim /usr/local/apache/conf/httpd.conf

而后把ServerName行改为ServerName 本地ip:80

把Listen 80行改为Listen 本地ip:80

而后保存，启动apache服务.

service httpd start
