1、安装依赖
#yum install curl-devel sqlite-devel libyaml-devel -y
2、安装rvm
#curl -L https://get.rvm.io | bash -s stable #网络问题可能失败，多执行几次
如果报错如下：
执行：
#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、安装ruby
#rvm list known #查看版本
#rvm install ruby-2.5.1
#gem -v #安装好以后查看版本
4、更改gem源
#gem source -l #查看镜像源
#gem source –remove https://rubygems.org/ #删除默认源
#gem sources --add https://gems.ruby-china.com/ #新增gem的镜像源(确保只有gems.ruby-china.com)
5、安装MySQL
a.给Centos添加rpm源，并且选择较新的源命令：
#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.安装MySQL服务器
#yum install mysql-community-server
#systemctl enable mysqld 设置开机启动
c、设置mysql的账号和密码，并创建redmine数据库
#systemctl start mysqld
#grep "password" /var/log/mysqld.log #查看默认密码
#mysql -u root -p
>set password=password('new password')
>ALTER USER 'root'@'localhost' PASSWORD EXPIRE NEVER; #密码永不过期
>flush privileges;
>create database redmine character set utf8; # 创建redmine数据库
>create user 'redmine'@'localhost' IDENTIFIED BY 'new password'; #设置用户redmine的密码
>grant all privileges on redmine.* to 'redmine'@'localhost'; #赋予redmine账号最大权限
> ALTER USER 'redmine'@'localhost' PASSWORD EXPIRE NEVER;#密码永不过期
>flush privileges;
6、安装rails和相关依赖包
#gem install rails
#gem install rake
#gem install mysql2 #如果报错就执行yum install mysql-devel
7、安装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 #如果报错An error occurred while installing rmagick (2.16.0), and Bundler cannot continue. 执行yum install ImageMagick-devel
8、配置redmine并初始化
#cp config/database.yml.example config/database.yml
#vim config/database.yml #选择product部分修改数据库密码
#rake generate_secret_token #如果报错Could not find gem 'mysql2 (~> 0.4.6)' in any of the gem sources listed in your Gemfile. 再次执行bundle install
#RAILS_ENV=production rake db:migrate #生成表结构
#RAILS_ENV=production rake redmine:load_default_data #初始化数据选择zh
9、启动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后台启动
#/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后台启动
10、添加启动脚本
# 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 #默认端口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、访问项目
#firewall-cmd –add-port=3000/tcp –permanent –zone=public #如果是80 此处就设置80
#firewall-cmd –reload
http://192.168.133.130:3000 初始账号admin 密码admin
12、备份或迁移
只需要备份（或者迁移）mysql的redmine库，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输入密码，解决办法
#vim /root/.my.cnf
[mysqldump]
user=yourusername
password=yourpassword
host=localhost
