UBUNTU18安装REDMINE

1. 安装APACHE2

sudo apt update
sudo apt install apache2 libapache2-mod-passenger

sudo systemctl stop apache2.service
sudo systemctl start apache2.service
sudo systemctl enable apache2.service

2. 安装数据库MYSQL

sudo apt-get install mysql-server

sudo systemctl stop mysql.service
sudo systemctl start mysql.service
sudo systemctl enable mysql.service

运行以下命令以保护MYSQL服务器的安全

sudo mysql_secure_installation         

New password: (输入密码)
Re-enter new password: (重复输入)
Remove anonymous users? [Y/n]: Y
Disallow root login remotely? [Y/n]: Y
Remove test database and access to it? [Y/n]:  Y
Reload privilege tables now? [Y/n]:  Y

3. 创建REDMINE数据库

sudo mysql -u root -p

mysql> create database redmine;
mysql> create user 'redmine'@'localhost' identified by '123456';
mysql> grant all on redmine.* to 'redmine'@'localhost' identified by '123456' with grant option;
mysql> flush privileges;
mysql> exit;

创建用户或授权时有可能报如下错误：

ERROR 1819 (HY000): Your password does not satisfy the current policy requirements

这是由于密码太简单，不满足安全策略造成的。查看MYSQL初始的密码策略：

mysql> show variables like 'validate_password%';
+--------------------------------------+-------+
| Variable_name                        | Value |
+--------------------------------------+-------+
| validate_password_check_user_name    | OFF   |
| validate_password_dictionary_file    |       |
| validate_password_length             | 6     |
| validate_password_mixed_case_count   | 1     |
| validate_password_number_count       | 1     |
| validate_password_policy             | LOW   |
| validate_password_special_char_count | 1     |
+--------------------------------------+-------+
7 rows in set (0.41 sec)

解决办法：1. 设置更复杂的密码，2. 降低安全策略：

set global validate_password_policy=LOW;
set global validate_password_length=6;

4. 安装REDMINE

sudo apt-get install redmine redmine-mysql

在安装过程中，系统将要求配置REDMINE，选择YES，然后继续。数据库选择MYSQL；接下来为REMIND实例创建一个密码以在数据库中注册，密码为上面创建的数据库用户的密码；接下来，安装GEM、BLUNDLER软件包。

sudo gem update
sudo gem install bundler

更新过程中会报如下错误，不过暂时可以忽略。

Fetching: mysql2-0.5.3.gem (100%)
Building native extensions. This could take a while...

5. 为REDMINE设置APACHE2站点。首先运行以下命令创建指向REDMINE文档根目录的软链接：

sudo ln -s /usr/share/redmine/public /var/www/html/redmine

6. 配置APACHE2

运行以下命令以打开PASSENGER.CONF文件：

sudo vim /etc/apache2/mods-available/passenger.conf

然后将突出显示的行添加到文件中并保存：

<IfModule mod_passenger.c>
    PassengerDefaultUser www-data
    PassengerRoot /usr/lib/ruby/vendor_ruby/phusion_passenger/locations.ini
    PassengerDefaultRuby /usr/bin/ruby
</IfModule>

为REDMINE配置APACHE2站点配置文件。该文件将控制用户访问REDMINE内容的方式。运行以下命令以创建一个名为REDMINE.CONF的新配置文件：

sudo vim /etc/apache2/sites-available/redmine.conf

<VirtualHost *:80>
     ServerAdmin redmime@xiem.com
     DocumentRoot /var/www/html/redmine
     ServerName xiem.com
     ServerAlias redmine.xiem.com

     <Directory /var/www/html/redmine>
         RailsBaseURI /redmine
         PassengerResolveSymlinksInDocumentRoot on
     </Directory>

     ErrorLog ${APACHE_LOG_DIR}/error.log
     CustomLog ${APACHE_LOG_DIR}/access.log combined

</VirtualHost>

7. 启用REDMINE站点

sudo a2ensite redmine.conf
sudo systemctl restart apache2.service

访问页面：http://redmine.xiem.com/
