Configuring Redmine under CentOS, as well as mail configuration and optimization

first, the installation of Redmine premise requirements 1. Installing the Redmine Ruby Environment version requires:

Redmine version	supported Ruby versions	Rails version used
3.3, current trunk	Ruby 1.9.3, 2.0.0, 2.1, 2.2, 2.3	Rails 4.2
3.2, 3.1	Ruby 1.9.3, 2.0.0, 2.1, 2.2	Rails 4.2

2. Can enter the server, and have administrator rights ii. Start installation of Redmine 1. Configuring the Environment

Note: Before installing the software, check to see if the server already has this software.

Yum -y install readline* libxslt* pcre* net-snmp* gmp* libtidy* yum-y  
install imagemagick* subversion*
yum-y Inst All wget  

2. Install MySQL (do not need to install if it already exists) Rpm-qa |grep MySQL

wget http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm
RPM-IVH mysql-community-release-el7-5.noarch.rpm
Yum Install mysql-community-server mysql-community-devel
Rpm-qa | grep MySQL #检查安装

3. Install RVM rvm-v

Curl-ssl Https://get.rvm.io | Bash
SOURCE/ETC/PROFILE/USR/LOCAL/RVM/BIN/RVM Reload
rvm-v #: The version number does not appear please reload

4. Install ruby Gem-v

RVM list known  #查看可安装列表
rvm install ruby-2.1.8  #官方只支持1.9~2.2 version
gem-v #如果未显示版本, reinstall Ruby  

5. Update the GEM source

Gem source-l 
gem source-r https://rubygems.org/  #: The default URL address must have "/", otherwise it will not be deleted.
gem source-a https://ruby.taobao.org/
gem source-l  #: Confirm only https://ruby.taobao.org/

6. Installing the Gem component

Gem Install rails  
gem install rake  
gem install MYSQL2  

7. Configure MySQL

Service mysqld start
mysql-u root-p
mysql> CREATE database redmine default character set UTF8;
Grant all on redmine.* to root;
Grant all on redmine.* to Root@localhost;
Grant all on redmine.* to Redmineuser;
Grant all on redmine.* to Redmineuser @localhost;
Set password for Redmine@localhost=password (' redmin ');
Flush privileges;  
Exit

8. Installing Redmine

Cd/home/xhy
wget http://www.redmine.org/releases/redmine-3.1.1.tar.gz
sudo tar-zxvf redmine-3.1.1.tar.gz
sudo mv redmine-3.1.1 redmine
cd/home/xhy/redmine/

9. Configure the Redmine data file

sudo cp config/configuration.yml.example config/configuration.yml
sudo cp config/database.yml.example config/ Database.yml
sudo vim/config/database.yml

production:
  adapter:mysql2  
  database:redmine    // MySQL created database
  host:localhost
  username:redmine//mysql user  name
  password:redmine  //mysql username
  Encoding:utf8
  port:8035      //ports needed to open

10. Install the tool that manages Ruby's package dependencies bundler

Cd/home/xhy/redmine
gem install bundler  #注意是在网站根目录下执行
Bundle Install 
If the download is slow you can modify ' sudo vim/usr/ Local/redmine/gemfile ' change ' source ' https://rubygems.org ' to ' source ' https://ruby.taobao.org/'

11. Initialize Redmine

Bundle EXEC Rake Generate_secret_token
rails_env=production bundle exec rake db:migrate
rails_env= Production bundle EXEC Rake Redmine:load_default_data #初始化数据选择zh 

12. Change Permissions

mkdir-p tmp tmp/pdf public/plugin_assets
sudo chmod-r 755 files log tmp public/plugin_assets

13. Turn on the service

Bundle EXEC Rails server-p 8035 webrick-e production-b 0.0.0.0-d

14. Close the service

PS aux | grep Ruby
sudo kill-9 PID

Redmine Post-installation follow-up work Open Redmine

Enter the IP address plus port number of the server, such as 192.168.1.xxx:8035 switch Ruby version number

RVM use 2.2.3--default Open Server port number

sudo firewall-cmd–add-port=9200/tcp–permanent
sudo systemctl restart Firewalld redmine mail configuration scheme

Open the Redmine configuration file, sudo vim config/configuration.yml, and then change the content to the following format:

Delivery_method:: Async_smtp
async_smtp_settings:
Address: "smtp.mxhichina.com"
port:465
SSL: True
authentication:: Login
domain: ' touchair.cn '
user_name: ' xx.xiao@touxxx.cn '  //email account
Password: "xxxxx"  //email password

Redmine A slow solution to access a page

Redmine when editing a task in the default configuration is blocked waiting for notification messages to be sent, you can modify it asynchronously: Modify the Delivery_method in the configuration file as: ASYNC_SMTP, and modify Smtp_settings to Async_smtp_ Settings, and then restart, is not much faster. redmine Data Migration

1. First machine: Mysqldump-u root-p redmine > File.sql
Copy the File.sql file to the computer that you want to migrate, and then execute the following statement
2. Second machine: Mysql-u root-p redmine < File.sql

After data migration, the original picture may be time-lapse, copy the Files folder of the first machine to the Files folder of the new computer, special note the version number

1, ruby:2.2.6
2, gem:2.6.12
3, rvm:1.29.2
4, bundler:1.15.3
