configservice自带eureka注册中心、配置写入configDB数据库、优先部署、为client提供服务
adminservice向eureka注册服务、与configservice共用数据库、为portal提供服务
configservice和adminservice组成一套环境、多个环境就得部署多套config和admin
portal是web端、各环境共用、只需部署一套、有自己单独的数据库

apollo需要使用数据库，如果是mysql，需要版本在5.6以上：

本次环境mysql部署在10.4.7.11上，使用mysql5.7，为测试简单起见，各环境数据库使用同一个，不做隔离

rpm -Uvh https://dev.mysql.com/get/mysql80-community-release-el7-1.noarch.rpm
yum -y install yum-utils
yum-config-manager --disable mysql80-community
yum-config-manager --enable mysql57-community
yum install mysql-server -y

cat >/etc/my.cnf <<'EOF'
[mysqld]
character_set_server = utf8mb4
collation_server = utf8mb4_general_ci
init_connect = "SET NAMES 'utf8mb4'"
[mysql]
default-character-set = utf8mb4
EOF

systemctl start  mysqld
systemctl enable mysqld
mysql -u root -p`grep password /var/log/messages|awk '{print $NF}'`
# 修改密码
> set global validate_password_policy=0;
> set global validate_password_length=1;
> set password=password('123456');
> flush privileges;
# 检查字符集：需要四个都是utf8mb4
> \s

configdb初始化脚本 portal初始化脚本

wget -O apolloconfig.sql https://raw.githubusercontent.com/ctripcorp/apollo/1.5.1/scripts/db/migration/configdb/V1.0.0__initialization.sql 
# 导入sql文件
mysql -uroot -p123456 < apolloconfig.sql
# 检查是否导入成功
mysql -uroot -p123456 -e "show databases;"|grep ApolloConfigDB

mysql -uroot -p123456
> grant INSERT,DELETE,UPDATE,SELECT on ApolloConfigDB.* to 'apollo'@'10.4.7.%'  identified by "123456";
# 修改数据
> use ApolloConfigDB
> update ServerConfig set Value='http://apollo-config.zq.com/eureka' where Id=1;

vi /var/named/zq.com.zone
mysql               A    10.4.7.11
apollo-config       A    10.4.7.10
apollo-admin        A    10.4.7.10
apollo-portal       A    10.4.7.10
# 重启并验证
systemctl restart named
dig -t A apollo-config.zq.com @10.4.7.11 +short

由于portal使用的是另一个portaldb，我们需要在数据库中新建portdb，并初始化

wget -O apollo-portal.sql https://raw.githubusercontent.com/ctripcorp/apollo/1.5.1/scripts/db/migration/portaldb/V1.0.0__initialization.sql
# 导入sql文件
mysql -uroot -p123456 < apollo-portal.sql
# 检查是否导入成功
mysql -uroot -p123456 -e "show databases;"|grep ApolloPortalDB

都使用

apollo

用户来管理数据库是为了方便,如果有相关的安全考虑可以给config和portal分别使用不同的数据库账号

mysql -uroot -p123456
> grant INSERT,DELETE,UPDATE,SELECT on ApolloPortalDB.* to "apollo"@"10.4.7.%" identified by "123456";
# 更新部门名
> update ApolloPortalDB.ServerConfig set Value='[{"orgId":"zq01","orgName":"研发部"},{"orgId":"zq02","orgName":"运维部"}]' where Id=2;

操作在

7.200

上完成

wget https://github.com/ctripcorp/apollo/releases/download/v1.5.1/apollo-configservice-1.5.1-github.zip
mkdir /data/dockerfile/apollo-configservice
unzip -o apollo-configservice-1.5.1-github.zip -d /data/dockerfile/apollo-configservice/

cd /data/dockerfile/apollo-configservice/config
# 修改数据库连接地址
sed -i 's#fill-in-the-correct-server#mysql.zq.com#g' application-github.properties
# 修改数据库连接用户和密码
sed -i 's#FillInCorrectUser#apollo#g'     application-github.properties
sed -i 's#FillInCorrectPassword#123456#g' application-github.properties
# 查看结果
config]# egrep -v "^#|$^" application-github.properties
spring.datasource.url = jdbc:mysql://mysql.zq.com:3306/ApolloConfigDB?characterEncoding=utf8
spring.datasource.username = apollo
spring.datasource.password = 123456

程序中自带的

start.sh

启动脚本时不适用与K8S运行,因此需要专门下载他们提供的K8S内使用的脚本

# 1.从官网下载启动脚本
cd /data/dockerfile/apollo-configservice/scripts/
wget https://raw.githubusercontent.com/ctripcorp/apollo/1.5.1/scripts/apollo-on-kubernetes/apollo-config-server/scripts/startup-kubernetes.sh
# 2. 添加一行使用主机名的变量
sed -i '5i APOLLO_CONFIG_SERVICE_NAME=$(hostname -i)' startup-kubernetes.sh
# 3.根据需要修改下jvm限制

dockerfile官方地址

cd ..
cat >Dockerfile <<'EOF'

cd /data/k8s-yaml/apollo-configservice

给configservice创建cm资源的清单的目的是方便修改

其实里面的内容就是前面修改的

application-github.properties

文件

如果确定不会修改,可以不创建此cm,直接写死配置到docker镜像中

cat >cm.yaml <<'EOF'
apiVersion: v1
kind: ConfigMap
metadata:
  name: apollo-configservice-cm
  namespace: infra
data:
  application-github.properties: |
    # DataSource
    spring.datasource.url = jdbc:mysql://mysql.zq.com:3306/ApolloConfigDB?characterEncoding=utf8
    spring.datasource.username = apollo
    spring.datasource.password = 123456
    eureka.service.url = http://apollo-config.zq.com/eureka
  app.properties: |
    appId=100003171
EOF

在同一个configmap资源中,可以添加多个配置文件,上述配置就有两个,分别是:

application-github.properties

和

app.properties

service中不一定必须暴露8080,分配的clusterIP中所有的端口都可以

但ingress中的servicePort一定要与service中暴露的端口匹配

kubectl create -f http://k8s-yaml.zq.com/apollo-configservice/cm.yaml
kubectl create -f http://k8s-yaml.zq.com/apollo-configservice/dp.yaml
kubectl create -f http://k8s-yaml.zq.com/apollo-configservice/svc.yaml
kubectl create -f http://k8s-yaml.zq.com/apollo-configservice/ingress.yaml

kubectl -n infra get pod|grep apollo-config
# 检查命令
kubectl -n infra logs apollo-configservice-64fc749978-9nz5h --tail=4

需要等到eureka启动以后才可以，接下来使用浏览器访问

apollo-config.zq.com

7.200

wget https://github.com/ctripcorp/apollo/releases/download/v1.5.1/apollo-adminservice-1.5.1-github.zip
mkdir /data/dockerfile/apollo-adminservice
unzip -o apollo-adminservice-1.5.1-github.zip -d /data/dockerfile/apollo-adminservice/

由于使用了configmap资源将配置文件挂载出来了，所以不在修改配置文件，如需修改配置文件，请参考部署apollo-configservice时候的修改方法：

start.sh

# 1.从官网下载启动脚本
cd /data/dockerfile/apollo-adminservice/scripts/
wget https://raw.githubusercontent.com/ctripcorp/apollo/1.5.1/scripts/apollo-on-kubernetes/apollo-admin-server/scripts/startup-kubernetes.sh
# 2. 添加一行使用主机名的变量
sed -i '5i APOLLO_CONFIG_SERVICE_NAME=$(hostname -i)' startup-kubernetes.sh
# 3.修改端口为8080
sed -i 's#8090#8080#g' startup-kubernetes.sh

官方配置文件端口改为8090的目的是虚拟机部署的时候端口不冲突

但我们用K8S部署,会给他单独的clusterIP,所以不用担心端口重复

cd ..
cat >Dockerfile <<'EOF'

ADD config/ /apollo-adminservice/config
ADD scripts/ /apollo-adminservice/scripts
CMD ["/bin/bash","/apollo-adminservice/scripts/startup-kubernetes.sh"]
EOF

由于要使用cm配置资源,因此就不改config中的配置了

docker build . -t harbor.zq.com/infra/apollo-adminservice:v1.5.1
docker push       harbor.zq.com/infra/apollo-adminservice:v1.5.1

adminservice向注册中心注册服务,不直接对外提供服务,因此不需要暴露端口,只需要cm资源和dp资源

mkdir /data/k8s-yaml/apollo-adminservice
cd /data/k8s-yaml/apollo-adminservice

cat >cm.yaml <<'EOF'
apiVersion: v1
kind: ConfigMap
metadata:
  name: apollo-adminservice-cm

    spring.datasource.username = apollo
    spring.datasource.password = 123456
    eureka.service.url = http://apollo-config.zq.com/eureka
  app.properties: |
    appId=100003172

通过 apollo-config.zq.com 检查是否注册到了eureka：

已经顺利的注册到了注册中心中。

portal官方地址

mkdir /data/dockerfile/apollo-portal
unzip -o apollo-portal-1.5.1-github.zip -d /data/dockerfile/apollo-portal/

由于使用concigmap资源，故不在这里修改

注意如果要修改的话,要分别修改两个文件

apollo-env.properties 修改数据库配置
apollo-env.properties 修改支持的环境列表

由于前面已经一起添加了域名解析,因此portal创建好后不需要在添加域名解析,直接浏览器登录验证

网页：apollo-portal.zq.com

默认用户名：apollo

默认密码：admin

登录成功后,立马修改密码为

apollo123

到此，apollo的三个组件都已经交付到k8s里了。

使用配置中心，需要开发对代码进行调整，将一些配置，通过变量的形式配置到apollo中，服务通过配置中心来获取具体的配置

项目属性：

AppId：dubbo-demo-service

应用名称：dubbo服务提供者

部门：研发部

为新项目添加配置如下：

发布后效果图如下：

还是使用之前的流水线，但是使用分支为apollo的代码进行打包，参数如下：

修改dp.yaml资源配置清单

将镜像改为刚刚打包的镜像名：
添加环境变量 C_OPTS ,以便指定配置中心

vim /data/k8s-yaml/dubbo-server/dp.yaml
#----------原内容----------
    spec:
      containers:

        ports:

          protocol: TCP

        - name: C_OPTS
          value: -Denv=dev -Dapollo.meta=http://apollo-config.zq.com

应用资源配置清单：

kubectl apply -f http://k8s-yaml.zq.com/dubbo-server/dp.yaml

AppId：dubbo-demo-web

应用名称：dubbo服务消费者

部门：运维部

略

构建完成后，修改资源配置清单并应用：
