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察派服务 。

命令如下

ps -ef|grep httpd

2）查看linux系统服务中有没庆纳有httpd

chkconfig --list | grep httpd

3）如果有服务存在，那么败差贺需要先关闭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）先检查 安装包 的名字

命令 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-boxfont-family: Monaco, Menlo, Consolas, "Courier New", monospacefont-size: 12pxwhite-space: pre-wrapdisplay: blockpadding: 9.5pxmargin: 0px 0px 10pxline-height: 1.38462color: rgb(51, 51, 51)word-break: break-alloverflow-wrap: break-wordbackground-color: rgb(245, 245, 245)border: 1px solid rgb(204, 204, 204)border-radius: 4pxfont-style: normalfont-variant-ligatures: normalfont-variant-caps: normalfont-weight: 400letter-spacing: normalorphans: 2text-align: starttext-indent: 0pxtext-transform: nonewidows: 2word-spacing: 0px-webkit-text-stroke-width: 0pxtext-decoration-thickness: initialtext-decoration-style: initialtext-decoration-color: initial">#先检查文件在哪

find / -name httpd.conf

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-boxfont-family: Monaco, Menlo, Consolas, "Courier New", monospacefont-size: 12pxwhite-space: pre-wrapdisplay: blockpadding: 9.5pxmargin: 0px 0px 10pxline-height: 1.38462color: rgb(51, 51, 51)word-break: break-alloverflow-wrap: break-wordbackground-color: rgb(245, 245, 245)border: 1px solid rgb(204, 204, 204)border-radius: 4pxfont-style: normalfont-variant-ligatures: normalfont-variant-caps: normalfont-weight: 400letter-spacing: normalorphans: 2text-align: starttext-indent: 0pxtext-transform: nonewidows: 2word-spacing: 0px-webkit-text-stroke-width: 0pxtext-decoration-thickness: initialtext-decoration-style: initialtext-decoration-color: initial">[www@istester ~]$ yum list httpd

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-boxfont-family: Monaco, Menlo, Consolas, "Courier New", monospacefont-size: 12pxwhite-space: pre-wrapdisplay: blockpadding: 9.5pxmargin: 0px 0px 10pxline-height: 1.38462color: rgb(51, 51, 51)word-break: break-alloverflow-wrap: break-wordbackground-color: rgb(245, 245, 245)border: 1px solid rgb(204, 204, 204)border-radius: 4pxfont-style: normalfont-variant-ligatures: normalfont-variant-caps: normalfont-weight: 400letter-spacing: normalorphans: 2text-align: starttext-indent: 0pxtext-transform: nonewidows: 2word-spacing: 0px-webkit-text-stroke-width: 0pxtext-decoration-thickness: initialtext-decoration-style: initialtext-decoration-color: initial">[root@istester www]# service httpd status

httpd (pid 10339) is running...</pre>

2）查看进程

<pre style="box-sizing: border-boxfont-family: Monaco, Menlo, Consolas, "Courier New", monospacefont-size: 12pxwhite-space: pre-wrapdisplay: blockpadding: 9.5pxmargin: 0px 0px 10pxline-height: 1.38462color: rgb(51, 51, 51)word-break: break-alloverflow-wrap: break-wordbackground-color: rgb(245, 245, 245)border: 1px solid rgb(204, 204, 204)border-radius: 4pxfont-style: normalfont-variant-ligatures: normalfont-variant-caps: normalfont-weight: 400letter-spacing: normalorphans: 2text-align: starttext-indent: 0pxtext-transform: nonewidows: 2word-spacing: 0px-webkit-text-stroke-width: 0pxtext-decoration-thickness: initialtext-decoration-style: initialtext-decoration-color: initial">[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 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

在centos下Apache的安装方式无非两种，源慎裂码编译安装和yum(rpm)安装，下面列出查找方式 1. 查找服务安装位置通常使用查找进程的方式，适用知昌于编译安装的apache，下面例子中宽猛闭可以看出来apache安装在/usr/local/httpd/下 ps -ef|egrep "apache|httpd"...
