[系统运维]k8s/docker 安装yapi和MongoDB

环境说明

centos7
防火墙 iptables

安装MongoDB

文档
https://mongodb.net.cn/manual/tutorial/install-mongodb-on-red-hat/

配置源

编辑文件

vim /etc/yum.repos.d/mongodb-org-4.2.repo

内容如下

[mongodb-org-4.2]
name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/4.2/x86_64/
gpgcheck=1
enabled=1
gpgkey=https://www.mongodb.org/static/pgp/server-4.2.asc

更新并安装

sudo yum update
sudo yum clean all
sudo yum makecache
sudo yum update
#
sudo yum install -y mongodb-org

查看安装位置

whereis mongod

设置开机启动

 systemctl enable mongod

启动

 systemctl start mongod

查看状态

 systemctl status mongod

如果有防火墙那么要配置防火墙

这里 只有iptables 防火墙

iptables -I INPUT -p tcp --dport 27017 -j ACCEPT

配置文件

vim /etc/mongod.conf

启动权限控制

security:
  authorization: enabled

authorization 启用基于角色的访问控制

如果你需要开启远程访问,把如下

bindIp: 127.0.0.1  # Enter 0.0.0.0,:: to bind to all IPv4 and IPv6 addresses or, alternatively, use the net.bindIpAll setting

改为

bindIp: 0.0.0.0

重启并应用

 systemctl restart mongod

配置文件限制

echo "mongod     soft    nofiles   64000" >> /etc/security/limits.conf
echo "mongod     soft    nproc     64000" >> /etc/security/limits.conf

创建数据库用户-超管

mongo

接着 进入 库

use admin

创建用户及权限

db.createUser({user: "fox", pwd: "pd.fox.123#@", roles:[{role: "userAdminAnyDatabase", db: "admin"}]})

fox : 管理员(该用户可以在任何数据库上创建其他用户)
pd.fox.123#@： 为密码

输出

Successfully added user: {
        "user" : "fox",
        "roles" : [
                {
                        "role" : "userAdminAnyDatabase",
                        "db" : "admin"
                }
        ]
}

退出

exit
或
quit()

案例-创建普通用户及库

登陆

mongo -u fox -p --authenticationDatabase admin

创建数据库

use yapi

给该库设置独立的用户及密码

本步骤不是必须的，你也可以使用超管用户fox

db.createUser({user: "yapi", pwd: "password", roles:[{role: "dbAdmin", db: "yapi"},{role: "readWrite", db: "yapi"}]})

最后退出

exit
或
quit()

命令行使用该用户登陆

mongo -u yapi -p --authenticationDatabase yapi

k8s 安装yapi

设置yapi配置文件

mkdir -p /www/yapi/conf
#
vim /www/yapi/conf/config.json

内容如下

{
   "port": "3000",
   "adminAccount": "foxiswho@gmail.com",
   "timeout":120000,
   "db": {
     "connectString": "mongodb://172.17.132.196:27017/yapi",
     "port": 27017,
     "user": "yapi",
     "pass": "password"
   },
   "mail": {
     "enable": true,
     "host": "smtp.gmail.com",
     "port": 465,
     "from": "*",
     "auth": {
       "user": "foxiswho@gmail.com",
       "pass": "yapi.pro"
     }
   }
 }

mail ： 配置邮件服务器，不需要可以删除无需配置

应用生成

kubectl apply -f pod.yaml
kubectl apply -f service.yaml
kubectl apply -f ingress.yaml

最后访问浏览器

http://yapi.foxwho.com

初始化管理员账号在上面的 config.json 配置中 foxiswho@gmail.com，初始密码是 yapi.pro，可以登录后进入个人中心修改

docker 安装yapi

设置yapi配置文件

mkdir -p /www/yapi/conf
#
vim /www/yapi/conf/config.json

内容如下

{
   "port": "3000",
   "adminAccount": "foxiswho@gmail.com",
   "timeout":120000,
   "db": {
     "connectString": "mongodb://172.17.132.196:27017/yapi?replicaSet=rs0&slaveOk=true",
     "port": 27017,
     "user": "yapi",
     "pass": "password"
   },
   "mail": {
     "enable": true,
     "host": "smtp.gmail.com",
     "port": 465,
     "from": "*",
     "auth": {
       "user": "foxiswho@gmail.com",
       "pass": "yapi.pro"
     }
   }
 }

拉取镜像

docker pull yapipro/yapi:latest

创建一个自定义网络

Docker 容器之间网络互通需要使用 docker network create yapi 创建一个自定义网络

docker network create yapi

容器初始化数据库表

docker run -d --rm \
  --name yapi-init \
  --net=yapi \
  -v $PWD/config.json:/yapi/config.json \
   yapipro/yapi \
  server/install.js

运行容器

初始化管理员账号在上面的 config.json 配置中 foxiswho@gmail.com，初始密码是 yapi.pro，可以登录后进入个人中心修改

docker run -d \
   --name yapi \
   --restart always \
   --net=yapi \
   -p 3000:3000 \
   -v /www/yapi/conf/config.json:/yapi/config.json \
   yapipro/yapi \
   server/app.js

在服务器上验证 yapi 启动是否成功

curl localhost:3000
