linux 安装测试工具禅道zentao 社区版18.0 及 apache的httpd.conf配置引入子配置多IP 多端口访问多站点

如果是纯净系统，未安装apache、php、mysql等，建议使用一键安装包安装！！！

https://www.zentao.net/download/zentaopms18.0-81998.html

下面是各软件单独安装：

一、安装Apache 、安装PHP、安装mysql

https://blog.csdn.net/torpidcat/article/details/128863891

https://blog.csdn.net/torpidcat/article/details/110265490

https://blog.csdn.net/torpidcat/article/details/97791950

二、下载、解压禅道：以开源版18.0 为例

下载及参考等：

https://www.zentao.net/download/zentaopms18.0-81998.html

选择服务器安装的php对应的版本包：上面安装的php是7.1 所以这里下载7.1对应的包

下载安装包 ZenTaoPMS.18.0.php7.1.zip 并上传到服务器 /var/www/html/ 下并解压：

解压到Apache的 /var/www/html目录下:解压后的禅道项目名称为 zentaopms

unzip ZenTaoPMS.18.0.php7.1.zip -d /var/www/html/
或者
unzip ZenTaoPMS.18.0.php7.1.zip

解压后顺手把zip包删掉

三、修改Apache配置指定端口对应的站点/项目：两种方式一种是增加一个端口，单独给禅道用，另一种是直接使用Apache默认的80端口

方式1：新增一个端口8100，单独给禅道用( 避免占用80端口)

查看端口是否可用，可用，则在防火墙添加这个端口：

查看端口是否占用无内容输出，表示未被占用

lsof -i tcp:8100

查看防火墙是否开通端口未找到则表示未开通

firewall-cmd --permanent --list-port

防火墙开通端口并重载防火墙使之生效

firewall-cmd --permanent --zone=public --add-port=8100/tcp

firewall-cmd --reload

一般 Apache的 /etc/httpd/conf/httpd.conf 文件最后一行，IncludeOptional 后默认是引入 conf.d目录下的所有.conf文件，如果能搜到这一行则不用改动，如果搜不到，就追加这一行代码并保存：IncludeOptional对应的值为 /etc/httpd/conf.d/*.conf ，如果值不同，则以文件内的值为准

httpd.conf 文件默认配置：

#
# This is the main Apache HTTP server configuration file.  It contains the
# configuration directives that give the server its instructions.
# See <URL:http://httpd.apache.org/docs/2.4/> for detailed information.
# In particular, see 
# <URL:http://httpd.apache.org/docs/2.4/mod/directives.html>
# for a discussion of each configuration directive.
#
# Do NOT simply read the instructions in here without understanding
# what they do.  They're here only as hints or reminders.  If you are unsure
# consult the online docs. You have been warned.  
#
# Configuration and logfile names: If the filenames you specify for many
# of the server's control files begin with "/" (or "drive:/" for Win32), the
# server will use that explicit path.  If the filenames do *not* begin
# with "/", the value of ServerRoot is prepended -- so 'log/access_log'
# with ServerRoot set to '/www' will be interpreted by the
# server as '/www/log/access_log', where as '/log/access_log' will be
# interpreted as '/log/access_log'.#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# Do not add a slash at the end of the directory path.  If you point
# ServerRoot at a non-local disk, be sure to specify a local disk on the
# Mutex directive, if file-based mutexes are used.  If you wish to share the
# same ServerRoot for multiple httpd daemons, you will need to change at
# least PidFile.
#
ServerRoot "/etc/httpd"#
# Listen: Allows you to bind Apache to specific IP addresses and/or
# ports, instead of the default. See also the <VirtualHost>

# Dynamic Shared Object (DSO) Support
#
# To be able to use the functionality of a module which was built as a DSO you
# have to place corresponding `LoadModule' lines at this location so the
# directives contained in it are actually available _before_ they are used.

# to be loaded here.
#
# Example:

IncludeOptional conf.d/*.conf

通过上面的httpd.conf最后一行，可知通用配置文件存放目录是 /etc/httpd/conf.d/

新增一个针对这个端口/禅道项目/或其它站点的Apache配置文件名字随意取以.conf为后缀就行：/etc/httpd/conf.d/01_httpd_zentao.conf

cd /etc/httpd/conf.d/

新增一个配置文件(Apache的httpd.conf IncludeOptional配置会默认加载目录下的这个文件)

touch 01_httpd_zentao.conf
vi 01_httpd_zentao.conf
#或者直接vi 命令编辑如果不存在这个文件，则会自动创建
vi 01_httpd_zentao.conf

编辑 /etc/httpd/conf.d/01_httpd_zentao.conf，新增两个端口对应的项目：

（提一下文件名用 01_ 开头：网上找资料，据说httpd.conf加载子配置文件的时候，是用名称排序加载的，用01_开头，会优先加载当前子文件）

参考：https://blog.csdn.net/Eliauk22/article/details/122599027

01_httpd_zentao.conf的内容 (123.456.78.9为示例IP地址)：

新增一个8102端口对应的站点用于多站点的对照测试：

/var/www/html/目录下创建一个other目录，新建并且编辑index.html内容

index.html 内容：

<!doctype html>
<html>
<head><meta charset="utf-8"><title>other</title>
</head>
<body><h1>Other</h1>
</body>
</html>

重启Apache ：会自动载入 /etc/httpd/conf.d/下的所有 .conf 文件

systemctl restart httpd

测试IP下各站点是否可以正常访问：

Apache默认端口 :80

http://123.456.78.9

或

http://123.456.78.9:80

禅道： 8100

http://123.456.78.9:8100/

对照测试站点： 8102

http://123.456.78.9:8102

方式2：将Apache默认的80端口指向禅道项目（不推荐这种方式因为会占用80端口访问IP地址会默认跳转到80端口）：

编辑Apache的配置文件:修改两处禅道项目目录及一个配置项：在原配置目录后追加禅道项目下的子目录 zentaopms/www 、设置 AllowOverride值为 All

vi /etc/httpd/conf/httpd.conf

i 键进入编辑模式，编辑成功后，esc键， :wq 保存并退出编辑模式

修改DocumentRoot、Directory节点的项目根目录及节点下的AllowOverride值：
