1、安裝依賴
#yum install curl-devel sqlite-devel libyaml-devel -y
2、安裝rvm
#curl -L https://get.rvm.io | bash -s stable #網絡問題可能失敗，多執行幾次
如果報錯如下：
執行：
#gpg2 –recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3
#curl -L https://get.rvm.io | bash -s stable
#echo "source /etc/profile.d/rvm.sh" >> /root/.bashrc
#source /etc/profile.d/rvm.sh
3、安裝ruby
#rvm list known #查看版本
#rvm install ruby-2.5.1
#gem -v #安裝好以后查看版本
4、更改gem源
#gem source -l #查看鏡像源
#gem source –remove https://rubygems.org/ #刪除默認源
#gem sources --add https://gems.ruby-china.com/ #新增gem的鏡像源(確保只有gems.ruby-china.com)
5、安裝MySQL
a.給Centos添加rpm源，並且選擇較新的源命令：
#wget http://dev.mysql.com/get/mysql57-community-release-el7-7.noarch.rpm
#yum -y install mysql57-community-release-el7-7.noarch.rpm
#yum repolist all | grep mysql
#yum-config-manager –disable mysql55-community
#yum-config-manager –disable mysql56-community
#yum-config-manager –enable mysql57-community
#yum repolist enabled | grep mysql
b.安裝MySQL服務器
#yum install mysql-community-server
#systemctl enable mysqld 設置開機啟動
c、設置mysql的賬號和密碼，並創建redmine數據庫
#systemctl start mysqld
#grep "password" /var/log/mysqld.log #查看默認密碼
#mysql -u root -p
>set password=password('new password')
>ALTER USER 'root'@'localhost' PASSWORD EXPIRE NEVER; #密碼永不過期
>flush privileges;
>create database redmine character set utf8; # 創建redmine數據庫
>create user 'redmine'@'localhost' IDENTIFIED BY 'new password'; #設置用戶redmine的密碼
>grant all privileges on redmine.* to 'redmine'@'localhost'; #賦予redmine賬號最大權限
> ALTER USER 'redmine'@'localhost' PASSWORD EXPIRE NEVER;#密碼永不過期
>flush privileges;
6、安裝rails和相關依賴包
#gem install rails
#gem install rake
#gem install mysql2 #如果報錯就執行yum install mysql-devel
7、安裝redmine
#wget https://www.redmine.org/releases/redmine-3.4.6.tar.gz
#tar -zxvf redmine-3.4.6.tar.gz
#mv redmine-3.4.6 /usr/local/redmine
#cd /usr/local/redmine
#bundle install #如果報錯An error occurred while installing rmagick (2.16.0), and Bundler cannot continue. 執行yum install ImageMagick-devel
8、配置redmine並初始化
#cp config/database.yml.example config/database.yml
#vim config/database.yml #選擇product部分修改數據庫密碼
#rake generate_secret_token #如果報錯Could not find gem 'mysql2 (~> 0.4.6)' in any of the gem sources listed in your Gemfile. 再次執行bundle install
#RAILS_ENV=production rake db:migrate #生成表結構
#RAILS_ENV=production rake redmine:load_default_data #初始化數據選擇zh
9、啟動redmine
#nohup /usr/local/rvm/rubies/ruby-2.5.1/bin/ruby /usr/local/redmine/bin/rails server -e production -b 0.0.0.0 >/dev/null 2>&1 & #nohup后台啟動
#/usr/local/rvm/rubies/ruby-2.5.1/bin/ruby /usr/local/redmine/bin/rails server -e production -b 0.0.0.0 -d #或者-d后台啟動
10、添加啟動腳本
# vim /etc/init.d/redmined
#!/bin/bash
#redmine Startup script for the redmine server
#chkconfig: 2345 85 15
Prog=redmine
#find the redmine's pid
Pid=`ps aux | grep "\<$Prog\>" | pidof ruby`
ProgPort=80 #默認端口3000
ReturnCode=`ss -tlnp | awk -F' ' '{print$4}' | grep "\<$ProgPort\>" &> /dev/null;echo $?`
start() {
if [ $ReturnCode -eq 0 ] &> /dev/null;then
echo " Redmine is Already Running !!! "
else
/usr/local/rvm/rubies/ruby-2.5.1/bin/ruby /usr/local/redmine/bin/rails server -e production -b 0.0.0.0 -p $ProgPort -d >/dev/null
echo -e "Starting redmine ….. \e[32m[ OK ]\e[m"
fi
}
stop() {
if [ $ReturnCode -ne 0 ] &> /dev/null;then
echo " Redmine is Already Stopped !!!"
else
kill -9 $Pid
echo -e "Stopping redmine ….. \e[32m[ OK ]\e[m"
fi
}
status() {
if [ $ReturnCode -eq 0 ] &> /dev/null;then
echo " Redmine is Running !!! "
else
echo " Redmine is Stopped !!! "
fi
}
case "$1" in
start)
start
;;
stop)
stop
;;
status)
status
;;
restart)
stop
start
;;
*)
echo "Usage: $Prog {start|stop|status|restart}"
Esac
#chmod +x /etc/init.d/redmined
#/etc/init.d/redmined start
#chkconfig –add redmined
11、訪問項目
#firewall-cmd –add-port=3000/tcp –permanent –zone=public #如果是80 此處就設置80
#firewall-cmd –reload
http://192.168.133.130:3000 初始賬號admin 密碼admin
12、備份或遷移
只需要備份（或者遷移）mysql的redmine庫，config下面的yml配置文件，以及files下面的附件。
#!/bin/bash
bk_time=`date +"%Y%m%d"`
redmine_dir='/usr/local/redmine'
cd $redmine_dir
tar -zcf /root/backup_data/files/conf_file_${bk_time}.tar.gz files/ config/*.yml &> /dev/null
mysqldump redmine | gzip > /root/backup_data/mysql/redmine_${bk_time}.sql.gz
注意: mysql5.6以后不能在命令行直接輸入密碼，解決辦法
#vim /root/.my.cnf
[mysqldump]
user=yourusername
password=yourpassword
host=localhost
