Apache部署与虚拟主机

资源列表

基础环境

• 关闭防火墙

systemctl stop firewalld
systemctl disable firewalld

• 关闭内核安全机制

setenforce 0
sed -i "s/^SELINUX=.*/SELINUX=disabled/g" /etc/selinux/config

• 修改主机名

hostnamectl set-hostname apache

一、安装依赖

yum -y install gcc gcc-* make
yum -y install apr-util-devel pcre-devel zlib-devel

二、源码编译及安装

1、解包

tar zxf httpd-2.4.25.tar.gz -C /usr/src
cd /usr/src/httpd-2.4.25/

2、配置编译安装

./configure --prefix=/usr/local/httpd --enable-so --enable-rewrite --enable-charset-lite --enable-cgi
# --prefix：指定将 httpd 服务程序安装到哪个目录下，如/usr/local/httpd
# --enable-so：启用动态加载模块支持，使 httpd 具备进一步扩展功能的能力。
# --enable-rewrite：启用网页地址重写功能，用于网站优化及目录迁移维护。
# --enable-charset-lite：启用字符集支持，以便支持使用各种字符集编码的网页。
# --enable-cgi：启用 CGI 脚本程序支持，便于扩展网站的应用访问能力。

make && make install

3、优化执行路径

• 通过源码编译安装的 httpd 服务，程序路径并不在系统默认的搜索路径中，为了使 该服务在使用时更加方便，可以为相关程序添加符号链接

ln -s /usr/local/httpd/bin/* /usr/local/bin
ls -l /usr/local/bin/httpd /usr/local/bin/apachectl

4、添加为系统服务

• 在/lib/systemd/system/目录下，建立一个以.service 结尾的单元（unit）配置文件， 用于控制由 Systemd 管理或监控的 httpd 服务

cat > /lib/systemd/system/httpd.service << 'EOF'
[Unit]
Description=The Apache HTTP Server
After=network.target
[Service]
Type=forking
PIDFile=/usr/local/httpd/logs/httpd.pid
ExecStart= /usr/local/bin/apachectl $OPTIONS
ExecrReload= /bin/kill -HUP $MAINPID
[Install]
WantedBy=multi-user.target
EOF

systemctl start httod.service
systemctl enable httpd.service
systemctl is-enabled httpd.service

三、虚拟主机

1、基于域名的虚拟主机

# 为虚拟主机准备网页文档
mkdir -p /var/www/html/kgccom
mkdir -p /var/www/html/kccecom
echo "<h1>www.kgc.com</h1>"> /var/www/html/kgccom/index.html
echo "<h1>www.kcce.com</h1>"> /var/www/html/kccecom/index.html

2、添加虚拟主机配置

vi /usr/local/httpd/conf/extra/httpd-vhosts.conf


//创建独立的配置文件
<VirtualHost *:80>
    DocumentRoot "/var/www/html/kgccom"
    ServerName www.kgc.com
    ErrorLog "logs/www.kgc.com.error_log"
    CustomLog "logs/www.kgc.com.access_log" common
<Directory "/var/www/html">
    Require all granted
</Directory>
</VirtualHost>


<VirtualHost *:80>
    DocumentRoot "/var/www/html/kccecom"
    ServerName www.kcce.com
    ErrorLog "logs/www.kcce.com.error_log"
    CustomLog "logs/www.kcce.com.access_log" common
<Directory "/var/www/html">
    Require all granted
</Directory>
</VirtualHost>


//加载独立的配置文件
vi /usr/local/httpd/conf/httpd.conf
Include conf/extra/httpd-vhosts.conf


# 重启服务
systemctl restart httpd

3、基于 IP 地址、基于端口的虚拟主机

• 基于 IP 地址的虚拟主机

vi /usr/local/httpd/conf/extra/httpd-vhosts.conf


//创建独立的配置文件
<VirtualHost 192.168.72.154:80>
    DocumentRoot "/var/www/html/kgccom"
    ServerName www.kgc.com
    ErrorLog "logs/www.kgc.com.error_log"
    CustomLog "logs/www.kgc.com.access_log" common
<Directory "/var/www/html">
    Require all granted
</Directory>
</VirtualHost>


<VirtualHost 192.168.72.154:80>
    DocumentRoot "/var/www/html/kccecom"
    ServerName www.kcce.com
    ErrorLog "logs/www.kcce.com.error_log"
    CustomLog "logs/www.kcce.com.access_log" common
<Directory "/var/www/html">
    Require all granted
</Directory>
</VirtualHost> 

• 基于端口的虚拟主机

vi /usr/local/httpd/conf/extra/httpd-vhosts.conf


//创建独立的配置文件
<VirtualHost 192.168.72.154:81>
    DocumentRoot "/var/www/html/kgccom"
    ServerName www.kgc.com
    ErrorLog "logs/www.kgc.com.error_log"
    CustomLog "logs/www.kgc.com.access_log" common
<Directory "/var/www/html">
    Require all granted
</Directory>
</VirtualHost>


<VirtualHost 192.168.72.154:82>
    DocumentRoot "/var/www/html/kccecom"
    ServerName www.kcce.com
    ErrorLog "logs/www.kcce.com.error_log"
    CustomLog "logs/www.kcce.com.access_log" common
<Directory "/var/www/html">
    Require all granted
</Directory>
</VirtualHost>


# 还需要再主配置文件添加 Listen 进行监听端口
