>#Kubernetes安装 Apollo [TOC] tn2>首先安装存储。 ## Centos 安装nfs ```bash 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 ```bash 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 ```bash apt install nfs-common -y yum install -y nfs-utils ``` ### 安装NFS Storage ```bash 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 ```  ```bash 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 ```bash 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 ```bash helm repo add apollo https://charts.apolloconfig.com helm search repo apollo kubectl create ns apollo ``` ```bash 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 . ├── apollo-service │ ├── Chart.yaml │ ├── templates │ └── values.yaml ├── apollo-service-xxx.tgz └── values-test.yaml ``` ### 创建数据库 ```bash # 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;
