Kubernetes安装 Apollo

• Kubernetes安装 Apollo
  • Centos 安装nfs
    • Ubuntu 安装nfs
    • k8s工作节点安装nfs
    • 安装NFS Storage
  • 安装Mysql
  • Apollo
    • 创建数据库
  • 安装 apollo-portal

首先安装存储。

Centos 安装nfs

systemctl stop firewalld
systemctl disable firewalld
yum install -y nfs-common nfs-utils
mkdir /nfsdata
chmod 666 /nfsdata
vi /etc/exports
/nfsdata *(rw,async)
exportfs -rv
systemctl start rpcbind
systemctl start nfs
systemctl enable rpcbind.service nfs
showmount -e
yum install -y nfs-utils

Ubuntu 安装nfs

apt-get install nfs-kernel-server -y
sudo ufw disable
mkdir /nfsdata
chmod 666 /nfsdata
echo "/nfsdata *(async,insecure,no_root_squash,no_subtree_check,rw)" > /etc/exports
cat /etc/exports
/etc/init.d/nfs-kernel-server restart
showmount -e

k8s工作节点安装nfs

apt install nfs-common -y
yum install -y nfs-utils

安装NFS Storage

wget https://github.com/kubernetes-sigs/nfs-subdir-external-provisioner/releases/download/nfs-subdir-external-provisioner-4.0.16/nfs-subdir-external-provisioner-4.0.16.tgz
#解压
tar -xvf nfs-subdir-external-provisioner-4.0.16.tgz
cd nfs-subdir-external-provisioner
ifconfig
vim values.yaml

kubectl create ns nfs
helm install  nfs-subdir-external-provisioner . -n nfs
kubectl patch storageclass nfs-client -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}'

安装Mysql

helm repo add my-repo https://charts.bitnami.com/bitnami
kubectl create ns mysql
helm install my-release \
  --set auth.rootPassword=bob \
  --set auth.username=bob \
  --set auth.password=bob \
  -n mysql \
    my-repo/mysql
MYSQL_ROOT_PASSWORD=$(kubectl get secret --namespace mysql my-release-mysql -o jsonpath="{.data.mysql-root-password}" | base64 -d)
echo $MYSQL_ROOT_PASSWORD

Apollo

helm repo add apollo https://charts.apolloconfig.com
helm search repo apollo
kubectl create ns apollo

mkdir -p /root/apollo/apollo-service/ && cd /root/apollo/apollo-service/
# 拉取 chart 到本地 /root/apollo/apollo-service/ 目录
helm pull apollo/apollo-service --version 0.5.1
tar -zxvf apollo-service-0.5.1.tgz
cp apollo-service/values.yaml ./values-test.yaml
# 查看当前目录层级
tree -L 2

创建数据库

# 获取数据库初始化语句
# https://github.com/apolloconfig/apollo/blob/master/scripts/sql/apolloconfigdb.sql
# https://raw.githubusercontent.com/apolloconfig/apollo/master/scripts/sql/apolloconfigdb.sql 
wget https://raw.githubusercontent.com/apolloconfig/apollo/master/scripts/sql/apolloconfigdb.sql -O /tmp/apolloconfigdb.sql
cat /tmp/apolloconfigdb.sql
kubectl cp /tmp/apolloconfigdb.sql mysql/my-release-mysql-0:/tmp/apolloconfigdb.sql
kubectl exec -n mysql -it pod/my-release-mysql-0 /bin/bash
# 连接部署好的 Mysql 数据，创建 apollo 账户和数据库
mysql -uroot -p
# 或 mysql -h mysql_host -u root -p root123
mysql > create database ApolloConfigDB default character set utf8mb4 collate utf8mb4_unicode_ci;
mysql > create user 'apollo'@'%' identified by 'apollo';
mysql > grant all on ApolloConfigDB.* to 'apollo'@'%';
# 老版本 mysql > grant all on ApolloConfigDB.* to 'bob'@'%' identified by 'bob';
# 执行数据库初始化语句
mysql > source /tmp/apolloconfigdb.sql;

vim values-test.yaml
configdb:
  name: apollo-configdb
  host: "my-release-mysql.mysql"
  port: 3306
  dbName: ApolloConfigDB
  userName: "apollo"
  password: "apollo"

helm -n apollo install apollo-service apollo-service -f values-test.yaml | tee test.log
helm -n apollo list

安装 apollo-portal

helm repo add apollo https://www.apolloconfig.com/charts/
helm repo update
helm search repo apollo-portal
mkdir -p /root/apollo/apollo-portal/ && cd /root/apollo/apollo-portal/
# 拉取 chart 到本地 /root/apollo/apollo-portal/ 目录
helm pull apollo/apollo-portal --version 0.5.1
tar -zxvf apollo-portal-0.5.1.tgz
cp apollo-portal/values.yaml ./values-test.yaml

helm -n apollo install apollo-portal apollo-portal -f values-test.yaml | tee test.log
helm -n apollo list

export POD_NAME=$(kubectl get pods --namespace apollo -l "app=apollo-portal" -o jsonpath="{.items[0].metadata.name}")
echo "Visit http://0.0.0.0:8070 to use your application"
kubectl --address 0.0.0.0 --namespace apollo port-forward $POD_NAME 8070:8070
