一、描述

CentOS安装Apache服务可以有两种方式，一种是用yum安装，一种是从官网下载源代码进行安装。

二、使用yum安装Apache服务

步骤1：在命令行输入如下语句可以使用yum在线更新方式进行安装：

[tong@tong /]$ sudo yum install httpd -y

注意：采用该方式进行安装配置文件的默认路径为：/etc/httpd/conf/httpd.conf

步骤二：配置防火墙，添加下面红色字体的一行，表示开启80端口供客户浏览。

?


[tong        @tong        /]$ sudo vi /etc/sysconfig/iptables       
        -A INPUT -m state --state NEW -m tcp -p tcp --dport         22        -j ACCEPT       
        # Firewall configuration written by system-config-firewall       
        # Manual customization of         this        file is not recommended.       
        *filter       
        :INPUT ACCEPT [        0        :        0        ]       
        :FORWARD ACCEPT [        0        :        0        ]       
        :OUTPUT ACCEPT [        0        :        0        ]       
        -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT       
        -A INPUT -p icmp -j ACCEPT       
        -A INPUT -i lo -j ACCEPT       
        -A INPUT -m state --state NEW -m tcp -p tcp --dport         22        -j ACCEPT       
        -A INPUT -m state --state NEW -m tcp -p tcp --dport         80        -j ACCEPT       
        -A INPUT -j REJECT --reject-with icmp-host-prohibited       
        -A FORWARD -j REJECT --reject-with icmp-host-prohibited


步骤三：配置完防火墙之后需要重新启动防火墙

?



[tong        @tong        /]$ sudo service iptables restart       
        iptables: Setting chains to policy ACCEPT: filter [ OK ]       
        iptables: Flushing firewall rules: [ OK ]       
        iptables: Unloading modules: [ OK ]       
        iptables: Applying firewall rules: [ OK ]



步骤四;Apache配置完成后，则可启动服务

?



[tong        @tong        /]$ sudo service httpd start       
        Starting httpd: httpd: apr_sockaddr_info_get() failed         for        tong       
        httpd: Could not reliably determine the server's fully qualified domain name, using         127.0        .        0.1        for        ServerName       
        [ OK ]



注意：虽然这里可以启动但是报错，这是因为没有在Apache服务器的配置文件中添加ServerName参数，所以我们要在配置文件中配置这个参数

步骤5：我们查看我们的hostname主机名，并将该主机名添加到Apache配置文件的ServerName参数中

?



[tong        @tong        /]$ hostname       
        tong       
        [tong        @tong        /]$ cat /etc/sysconfig/network       
        NETWORKING=yes       
        HOSTNAME=tong



由上述的hostname为tong，则编辑Apache配置文件

[tong@tong conf]$ sudo vi /etc/httpd/conf/httpd.conf
在其中加入一行：ServerName tong:80

步骤5：重新启动Apache服务，则不会报错

?



[tong        @tong        conf]$ sudo service httpd restart       
        Stopping httpd: [ OK ]       
        Starting httpd: [ OK ]



步骤6：测试范例网页

在本机浏览器输入:http://本机IP地址，我的IP为：192.168.200.5,，我在浏览器上输入：http://192.168.200.5



三、使用源代码安装Apache服务

步骤1：下载源代码文件

[tong@tong tongSoftware]$ sudo wget http://mirror.bit.edu.cn/apache//httpd/httpd-2.4.12.tar.gz
步骤2；解压并安装
[tong@tong tongSoftware]$ sudo tar xzvf httpd-2.4.12.tar.gz

进入该解压后的目录，输入如下命令：

?



[tong        @tong        httpd-        2.2        .        29        ]$ sudo ./configure       
                
        configure: error: in `/usr/local/tongSoftware/httpd-        2.2        .        29        /srclib/apr':       
        configure: error: no acceptable C compiler found in $PATH       
        See `config.log'         for        more details       
        configure failed         for        srclib/apr



系统提示未安装gcc编译器，则安装该编译器

[tong@tong httpd-2.2.29]$ sudo yum install gcc
安装成功后重新编译源文件：
[tong@tong httpd-2.2.29]$ sudo ./configure //检查安装平台是否支持安装
[tong@tong httpd-2.2.29]$ sudomake //根据安装平台进行编译
[tong@tong httpd-2.2.29]$ sudomake install //安装软件
然后按照之前用yum安装的方法配置防火墙，启动Apache服务。
