BCS服务高可用安装

文档持续完善中~

该文档说明如何针对BCS Service层进行部署，其他请参照：

单机Mesos集群部署
Kubernetes高可用部署
Mesos集群高可用部署

依赖

etcd 3.12
docker
zookeeper
MongoDB 3
Harbor

概要说明

容器管理平台(BCS) 后台包含以下组件

bcs-api
bcs-dns
bcs-storage
bcs-ops
bcs-health-master
bcs-health-slave
bcs-mesos-driver
bcs-mesos-watch
bcs-container-executor
bcs-check
bcs-scheduler
bcs-client

安装部署

本地部署

Requirements:

操作系统： CentOS 7+
部署依赖服务：
- zookeeper，MongoDB，Docker, Harbor，etcd 等略
Note:

将已安装好的上述服务的相关信息准备好，以备用。如 IP, 域名，端口，账号密码等信息

准备证书文件

为方便，这里使用cfssl，cfssljson两个小工具来生成证书。需要实现准备证书生成配置文件

ca-csr.json，文件样例

{
    "CN": "bcs",
    "key": {
        "algo": "rsa",
        "size": 2048
    },
    "names": [
        {
            "C": "CN",
            "L": "SZ",
            "O": "TX",
            "ST": "GD",
            "OU": "CA"
        }
    ]
}

ca-config.json 文件样例：

{
    "signing": {
        "default": {
            "expiry": "43800h"
        },
        "profiles": {
            "server": {
                "expiry": "43800h",
                "usages": [
                    "signing",
                    "key encipherment",
                    "server auth"
                ]
            },
            "client": {
                "expiry": "43800h",
                "usages": [
                    "signing",
                    "key encipherment",
                    "client auth"
                ]
            },
            "peers": {
                "expiry": "43800h",
                "usages": [
                    "signing",
                    "key encipherment",
                    "server auth",
                    "client auth"
                ]
            }
        }
    }
}

生成ca证书
- 创建证书目录
- 生成ca根证书

cfssl gencert --initca ca-csr.json | cfssljson -bare bcs-ca

生成 bcs-ca.pem，bcs-ca.key 两个文件。etcd-ca.key文件可以保管到秘密位置，注意不要泄露，etcd-ca.pem 文件后续步骤备用

生成client及server证书

# bcs-client 证书
cfssl gencert -ca=bcs-ca.pem \
  -ca-key=bcs-ca-key.pem \
  -config=ca-config.json \
  -profile=client \
  ca-csr.json | cfssljson -bare bcs-client
  
# bcs-server 证书
cfssl gencert -ca=bcs-ca.pem \
  -ca-key=bcs-ca-key.pem \
  -config=ca-config.json \
  -profile=server \
  ca-csr.json | cfssljson -bare bcs-server

Note：

按照上述方式，生成 etcd 服务所需要的证书

准备配置文件

Note: 文档默认来源请参照编译文档。 Build 出来的产物中的配置文件模板与下述文件名不相同，默认为：config_file.template，为便于识别，以下配置文件名做了相应的调整。

启动服务

bcs所有服务启动使用统一的方式： <程序> -f <配置文件>

如： ./bcs-api -f bcs-api.json

将上述配置文件中的变量替换成对应的服务后，启动进程即可。

注意事项：

参考以下服务分布表表来进行服务的启动，后台层与集群层机器建议分别部署
master节点主机数为奇数

部署验证

参考 docs/features/bcs-client/bcs-client_HANDBOOK.md，使用bcs-client进行集群创建操作

接入蓝鲸社区版5.1+

首先确认要接入的目标社区版为5.1以上，带有bcs内容的版本: ls -l /data/src/bcs

1. 构建社区版规范化的目录结构

打包二进制

接入社区版中，并不是所有的二进制都需要，这里仅列出社区版需要的工程文件

因为社区版已经带有各工程的配置文件，因此，不需要再自行准备配置文件。

 bcs/server
  ├── bin
  │   ├── bcs-api
  │   ├── bcs-dns
  │   ├── bcs-health-master
  │   ├── bcs-health-slave
  │   ├── bcs-ops
  │   ├── bcs-storage
  └── VERSION

将版本号(可以自定义)写入VERSION 文件，如： github-1.1.0

可以用以下命令快速处理(在build目录下执行)

mkdir bin
cd build/bcs.295eb49-19.06.05/
tar zcf bcs-server-github-1.1.0.tgz bin/bcs-{api,dns,ops,storage,health-slave,health-master}

2. 替换社区版中的bcs 后台部分

登陆社区版中控机，执行备份，替换，安装操作。命令序列如下：

cd /data/src
rsync -a /data/src/bcs/server /data/backup/bcs/  # 备份

tar xvf bcs-server-github-1.1.0.tgz -C /data/src/bcs/server/  # 替换掉社区版中对应的二进制

## 执行安装
./bkcec sync bcs
echo api ops dns storage health-master health-slave | xargs -n1 ./bkcec stop bcs
echo api ops dns storage health-master health-slave | xargs -n1 ./bkcec install bcs
echo api ops dns storage health-master health-slave | xargs -n1 ./bkcec start bcs
