安装docker
- 参考美团云的一个教程--在CentOS上安装Docker
- 如果遇到启动服务时提示
WARN[0000] You are running linux kernel version 2.6.32-431.el6.x86_64, which might be unstable running docker. Please upgrade your kernel to 3.10.0.
INFO[0000] Listening for HTTP on unix (/var/run/docker.sock)
docker: relocation error: docker: symbol dm_task_get_info_with_deferred_remove, version Base not defined in file libdevmapper.so.1.02 with link time reference
参考[这个文章](http://collabnix.com/archives/1012)
yum-config-manager –enable public_ol6_latest
yum install device-mapper-event-libs
添加阿里云docker镜像加速器
sudo vim /etc/sysconfig/docker
// other_args="--registry-mirror=<your accelerate address>"
sudo service docker restart
sudo ps -ef | grep docker
配置redmine&mysql
-
镜像选择
- 官方的redmine镜像可配置项较少，选择使用sameersbn/redmine
拉取镜像
sudo docker pull sameersbn/redmine:3.3.2-1
sudo docker pull mysql:5.7.18
- 建立数据目录
mkdir -p /where/ever/you/like/mysql
mkdir -p /where/ever/you/like/mysql-conf
mkdir -p /where/ever/you/like/redmine-data
- 安装docker-compose
- 因为只安装了1.7.1版的docker，所以不能使用高版本的compose，只能用1.5.2配合version 1的yml文件使用
curl -L https://github.com/docker/compose/releases/download/1.5.2/docker-compose-
uname -s-uname -m> /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose
- 修改compose配置
- 获取基础模板
wget https://raw.githubusercontent.com/sameersbn/docker-redmine/master/docker-compose.yml
-
修改配置。注意设定密码。此处直接使用ROOT用户给redmine使用。
另外，使用QQ企业邮箱发送邮件，端口要使用25，
SMTP_USER要和之后redmine设置面板中的发件人保持一致，否则会报501错误。在映射的
/mnt/redmine/mysql-conf路径下添加xxx.cnf配置文件，保证mysql使用utf8mb4_unicode_ci
mysql.cnf
[mysqld]
collation-server = utf8mb4_unicode_ci
init-connect='SET NAMES utf8'
character-set-server = utf8
skip-character-set-client-handshake
[client]
default-character-set = utf8
[mysql]
default-character-set = utf8
docker-compose.yml
mysql:
image: mysql:5.7.18
environment:
- MYSQL_ROOT_PASSWORD=xxx
- MYSQL_DATABASE=redmine-production
volumes:
- /where/ever/you/like/mysql:/var/lib/mysql
- /where/ever/you/like/mysql-conf:/etc/mysql/conf.d
redmine:

- SMTP_AUTHENTICATION=:login
ports:
- "9124:80"
volumes:
- /where/ever/you/like/redmine-data:/home/redmine/data
- 启动docker container
docker-compose up //会自动根据配置更新container
-
iptables配置
- 如果默认的FORWARD规则是DROP的话，需要添加
iptables -A FORWARD -i docker0 -j ACCEPT
- 查看iptables nat
sudo iptables -t nat -L -n
- 查看当前iptables规则
sudo less /etc/sysconfig/iptables
- 如果重启iptables的话会导致docker无法启动容器
iptables: No chain/target/match by that name.
sudo service docker restart
- 配置nginx转发请求
- sameersbn/redmine镜像中已带nginx，可以直接映射出80端口使用，也可以再转接一层
