Centos 下Apache(httpd) 安装过程

其实,网上这块的部署文章非常多 。随便搜索,都有 。

这篇文章,老徐帮大家挑选几个比较重点的过程 & 命令 。

1. 有些linux 版本中已经预置了有Apache,并且已经是服务了,所有首先检查系统中是否已经存在httpd的服务

1)先检查服务器 上是否已经启动了此服务 。

命令如下

ps -ef|grep httpd

2)查看linux系统服务中有没有httpd

chkconfig –list | grep httpd

3)如果有服务存在,那么需要先关闭httpd服务自启动
命令 chkconfig httpd off

4)停止httpd服务
命令 service httpd stop

5)再次查看,是否有进程存在
命令 ps -ef|grep httpd

6)如果有进程存在,关闭进程
命令 kill -9 pid

  1. 卸载httpd

1)先检查安装包的名字

命令 rpm -qa|grep httpd

<pre style=”box-sizing: border-box; font-family: Monaco, Menlo, Consolas, “Courier New”, monospace; font-size: 12px; white-space: pre-wrap; display: block; padding: 9.5px; margin: 0px 0px 10px; line-height: 1.38462; color: rgb(51, 51, 51); word-break: break-all; overflow-wrap: break-word; background-color: rgb(245, 245, 245); border: 1px solid rgb(204, 204, 204); border-radius: 4px;”>[root@istester]~# rpm -qa|grep httpd
httpd-2.2.15-69.el6.centos.x86_64
httpd-tools-2.2.15-69.el6.centos.x86_64</pre>

2)根据安装包名字删除包

rpm -e httpd-tools-2.2.15-69.el6.centos.x86_64

rpm -e httpd-2.2.15-69.el6.centos.x86_64

3)删除httpd.conf文件

<pre class=”prettyprint” style=”box-sizing: border-box; font-family: Monaco, Menlo, Consolas, “Courier New”, monospace; font-size: 12px; white-space: pre-wrap; display: block; padding: 9.5px; margin: 0px 0px 10px; line-height: 1.38462; color: rgb(51, 51, 51); word-break: break-all; overflow-wrap: break-word; background-color: rgb(245, 245, 245); border: 1px solid rgb(204, 204, 204); border-radius: 4px;”>#先检查文件在哪
find / -name httpd.conf

查出之后根据路径逐一删除

rm /xxx/xxx/httpd.conf</pre>

3. 准备事项已完成,剩下的就是常规安装了 。

注:我们通过yum的方式,在线安装,非常简单 。

1)检查是否存在httpd包

<pre style=”box-sizing: border-box; font-family: Monaco, Menlo, Consolas, “Courier New”, monospace; font-size: 12px; white-space: pre-wrap; display: block; padding: 9.5px; margin: 0px 0px 10px; line-height: 1.38462; color: rgb(51, 51, 51); word-break: break-all; overflow-wrap: break-word; background-color: rgb(245, 245, 245); border: 1px solid rgb(204, 204, 204); border-radius: 4px;”>[www@istester ~]$ yum list httpd

2、安装Apache
yum install httpd

<pre style=”box-sizing: border-box; font-family: Monaco, Menlo, Consolas, “Courier New”, monospace; font-size: 12px; white-space: pre-wrap; display: block; padding: 9.5px; margin: 0px 0px 10px; line-height: 1.38462; color: rgb(51, 51, 51); word-break: break-all; overflow-wrap: break-word; background-color: rgb(245, 245, 245); border: 1px solid rgb(204, 204, 204); border-radius: 4px;”>Total 20 MB/s | 932 kB 00:00

Complete!</pre>

安装过程,不用理会,如果看到如上提示,说明安装成功了。

3、设置Apache服务的启动级别
chkconfig –levels 235 httpd on
Apache是一个服务,所以,可以通过设置服务的启动级别来让它启动。

4、启动服务

两种方式,

1)如下 /etc/init.d/httpd start

2)如下

service httpd start

5、查看服务是否正常启动

两种方式,

1)查看服务状态

<pre style=”box-sizing: border-box; font-family: Monaco, Menlo, Consolas, “Courier New”, monospace; font-size: 12px; white-space: pre-wrap; display: block; padding: 9.5px; margin: 0px 0px 10px; line-height: 1.38462; color: rgb(51, 51, 51); word-break: break-all; overflow-wrap: break-word; background-color: rgb(245, 245, 245); border: 1px solid rgb(204, 204, 204); border-radius: 4px;”>[root@istester www]# service httpd status
httpd (pid 10339) is running…</pre>

2)查看进程

<pre style=”box-sizing: border-box; font-family: Monaco, Menlo, Consolas, “Courier New”, monospace; font-size: 12px; white-space: pre-wrap; display: block; padding: 9.5px; margin: 0px 0px 10px; line-height: 1.38462; color: rgb(51, 51, 51); word-break: break-all; overflow-wrap: break-word; background-color: rgb(245, 245, 245); border: 1px solid rgb(204, 204, 204); border-radius: 4px;”>[root@istester www]# ps -ef|grep httpd | grep -v grep
root 10339 1 0 23:15 ? 00:00:00 /usr/sbin/httpd
apache 10341 10339 0 23:15 ? 00:00:00 /usr/sbin/httpd
apache 10342 10339 0 23:15 ? 00:00:00 /usr/sbin/httpd
apache 10343 10339 0 23:15 ? 00:00:00 /usr/sbin/httpd
apache 10344 10339 0 23:15 ? 00:00:00 /usr/sbin/httpd
apache 10345 10339 0 23:15 ? 00:00:00 /usr/sbin/httpd
apache 10346 10339 0 23:15 ? 00:00:00 /usr/sbin/httpd
apache 10347 10339 0 23:15 ? 00:00:00 /usr/sbin/httpd
apache 10348 10339 0 23:15 ? 00:00:00 /usr/sbin/httpd</pre>

补充,

1)停止服务

service httpd stop

2)重启服务

service httpd restart

6、安装之后的说明:

1)验证是否安装成功
现在打开http://ip地址,看看有没有Apache的默认页面出来了?如果有就对了。

2)安装目录说明
Apache默认将网站的根目录指向/var/www/html
默认的主配置文件是/etc/httpd/conf/httpd.conf
配置存储在的/etc/httpd/conf.d/目录
