Linux系统服务器上安装Apache

一、首先下载安装Apache需要的依赖包

APR、APR-Util、PCRE，gcc-c++、gcc

APR下载地址：http://apr.apache.org/download.cgi

APR-Util下载地址：http:/
4000
/apr.apache.org/download.cgi

PCRE下载地址：https://sourceforge.net/projects/pcre/files/pcre/

HTTPD下载地址：http://httpd.apache.org/download.cgi

在linux上操作  通过#wget  下载地址  下载安装包到linux上

下载APR:

#wget http://mirrors.tuna.tsinghua.edu.cn/apache//apr/apr-1.5.2.tar.gz
下载APR-Util:

#wget http://mirrors.tuna.tsinghua.edu.cn/apache//apr/apr-util-1.5.4.tar.gz
下载PCRE:

#wget  ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.41.tar.gz

下载HTTPD：

#wget http://mirrors.tuna.tsinghua.edu.cn/apache//httpd/httpd-2.4.27.tar.gz

下载并解压之后就如图所示：



二、Apache安装步骤

第一步：先查看一下是否存在gcc、gcc-c++



如果已经存在就可以不用安装了，不存在再安装

[root@iZ2ze5cti43o69css0svslZ lamp]# yum install  gcc-c++

[root@iZ2ze5cti43o69css0svslZ lamp]# yum install  gcc

第二步：安装包APR和APR-Util

1、安装Apr

因为刚开始已经将压缩包解压，所以直接进入apr文件（--prefix=/usr/local/apr这是在指定软件安装的目录，若该文件不存在，会自动生成apr空文件夹）

[root@iZ2ze5cti43o69css0svslZ lamp]# cd apr-1.5.2

[root@iZ2ze5cti43o69css0svslZ apr-1.5.2]# ./configure --prefix=/usr/local/apr



[root@iZ2ze5cti43o69css0svslZ apr-1.5.2]# make

[root@iZ2ze5cti43o69css0svslZ apr-1.5.2]# make install



这样表示Apr已经好了。

2、安装Apr-util

同理，apr-util压缩包已经解压好了，直接进入文件中

[root@iZ2ze5cti43o69css0svslZ lamp]# cd apr-util-1.5.4

[root@iZ2ze5cti43o69css0svslZ apr-util-1.5.4]# ./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr/bin/apr-1-config



[root@iZ2ze5cti43o69css0svslZ apr-util-1.5.4]# make

[root@iZ2ze5cti43o69css0svslZ apr-util-1.5.4]# make install



这样apr-util安装好了

第三步：安装PRCE

同样pcre安装包已经解压好了

[root@iZ2ze5cti43o69css0svslZ lamp]# cd pcre-8.41

[root@iZ2ze5cti43o69css0svslZ pcre-8.41]# ./configure --prefix=/usr/local/pcre-8.41



[root@iZ2ze5cti43o69css0svslZ pcre-8.41]# make

[root@iZ2ze5cti43o69css0svslZ pcre-8.41]# make install



出现这样就已经安装好了

第四步：安装HTTPD

[root@iZ2ze5cti43o69css0svslZ lamp]# cd httpd-2.4.27

[root@iZ2ze5cti43o69css0svslZ httpd-2.4.27]#  ./configure --prefix=/usr/local/apache --with-pcre=/usr/local/pcre-8.41 --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util

[root@iZ2ze5cti43o69css0svslZ httpd-2.4.27]# make

[root@iZ2ze5cti43o69css0svslZ httpd-2.4.27]# make install

安装完成

第五步：启动Aapache

[root@iZ2ze5cti43o69css0svslZ httpd-2.4.27]# /usr/local/apache/bin/apachectl start

第六步：访问Apache

在浏览器上输入ip访问出现如图所示，表示Apache安装成功。



Apache安装问题锦集

问题1：缺少包gcc-c++导致安装包apr-util不通过



一般出现这个错误是因为没有安装包gcc-c++，只要安装即可，安装步骤如步骤一所示。

问题2：checking for APR-util... configure: error: the --with-apr-util parameter is incorrect

[root@iZ2ze5cti43o69css0svslZ httpd-2.4.27]#  ./configure --prefix=/usr/local/apache  --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util

configure:

一般是由于APR-util没有安装成功，可以通过验证该目录是否为空来判断，因为你有时候执行了make，忘了执行make isntall命令有可能导致这个错误。

问题3：没有指定PCRE参数

[root@iZ2ze5cti43o69css0svslZ httpd-2.4.27]#  ./configure --prefix=/usr/local/apache  --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util

问题5：启动服务时报错

[root@iZ2ze5cti43o69css0svslZ httpd-2.4.27]#  /usr/local/apache/bin/apachectl start

AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using iZ2ze5cti43o69css0svslZ  .gfg1.esquel.com. Set the 'ServerName' directive globally to suppress this message

这个时候需要编辑httpd.conf配置文件，添加SeraverName的具体IP地址。如下所示

[root@iZ2ze5cti43o69css0svslZ  conf]# cd /usr/local/apache/conf/

[root@iZ2ze5cti43o69css0svslZ  conf]# ls

[root@iZ2ze5cti43o69css0svslZ  conf]# /usr/local/apache/bin/apachectl start

如果从其它电脑连接访问Apache时，输入url地址例如：http://192.168.9.122页面没有显示正常，而上面配置也OK，那么你必须关闭防火墙，有时候甚至需要重启电脑才能OK,重启Apache服务都无效。

[root@iZ2ze5cti43o69css0svslZ  conf]# chkconfig iptables off

[root@iZ2ze5cti43o69css0svslZ  conf]# chkconfig iptables off

[root@iZ2ze5cti43o69css0svslZ  conf]# /usr/local/apache/bin/apachectl restart

[root@iZ2ze5cti43o69css0svslZ  conf]# /usr/local/apache/bin/apachectl restart

注：用的是阿里云的服务器的话需要在网络与安全下的安全组中添加80端口
