如何部署Apollo
环境准备：
Apollo 采用 Java 语言开发,部署环境必须安装了 Java，版本要求：Java 1.8+。
Apollo 的数据存储在 Mysql 中，部署环境也需要安装 Mysql 数据库，版本要求：5.6.5+。
快速启动的脚本是 shell 编写的，要有 bash 环境，在 Linux/Mac 下无影响。
如果用户是 Windows 环境，需要安装 Git Bash（https://git-for-windows.github.io/）
检查Java版本
安装jdk1.8参考页面：https://blog.csdn.net/huangbaokang/article/details/99749296
[root@localhost /]# java -version
java version "1.8.0_121"
Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)
安装步骤：
1.下载Apollo压缩包
2.初始化数据库
3.修改demo.sh配置文件
4.连接mysql数据库，启动Apollo
1.快速启动安装包下载地址：https://github.com/nobodyiam/apollo-build-scripts
2.初始化数据库
Apollo 服务端需要两个数据库：ApolloPortalDB 和 ApolloConfigDB。
数据库、表的创建和样例数据的 sql 文件都在快速启动安装包的 sql 目录中，解压压缩包导入数据库即可。
连接MySQL：
使用docker部署mysql: https://www.cnblogs.com/haoprogrammer/p/11008786.html
mysql版本5.7.26
查看所有容器 docker ps -a
启动容器 docker start 216cf6d4897e
进入容器 docker exec -it mysql5.7 bash
[root@localhost ~]# docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
216cf6d4897e mysql:5.7.26 "docker-entrypoint.s…" 4 days ago Exited (255) 8 minutes ago 33060/tcp, 0.0.0.0:13306->3306/tcp mysql5.7
[root@localhost ~]# docker start 216cf6d4897e
216cf6d4897e
[root@localhost ~]# docker exec -it mysql5.7 bash
root@216cf6d4897e:/# mysql -u root -p
Enter password:

mysql>
3.修改demo.sh文件
[root@localhost apollo-build-scripts-master]# ls
apollo-all-in-one.jar client demo.sh docker-compose.yml Dockerfile images portal README.md service sql
数据库配置
url为数据库地址，192.168.20.20为服务器IP，13306为自己配置的MySQL端口号
username为MySQL的用户名
password登录mysql的密码
# apollo config db info
apollo_config_db_url=jdbc:mysql://192.168.20.20:13306/ApolloConfigDB?characterEncoding=utf8
apollo_config_db_username=root
apollo_config_db_password=123
# apollo portal db info
apollo_portal_db_url=jdbc:mysql://192.168.20.20:13306/ApolloPortalDB?characterEncoding=utf8
apollo_portal_db_username=root
apollo_portal_db_password=123
元数据需修改服务器IP地址
# meta server url
config_server_url=http://192.168.20.20:8080
admin_server_url=http://192.168.20.20:8090
eureka_service_url=$config_server_url/eureka/
portal_url=http://192.168.20.20:8070
4.连接数据库，启动Apollo
首先确保数据库连接成功
退出mysql，启动Apollo
在bin目录下启动：./demo.sh start
mysql> exit;
Bye
root@216cf6d4897e:/# exit
exit
[root@localhost ~]# cd /usr/local/apollo-build-scripts-master/
[root@localhost apollo-build-scripts-master]# ./demo.sh start
==== starting service ====
Service logging file is ./service/apollo-service.log
Started [2226]
Waiting for config service startup.............
Config service started. You may visit http://192.168.20.20:8080 for service status now!
Waiting for admin service startup.......
Admin service started
==== starting portal ====
Portal logging file is ./portal/apollo-portal.log
Started [2437]
Waiting for portal startup...............
Portal started. You can visit http://192.168.20.20:8070 now!
接下来就可以访问Apollo的web管理界面了
默认账号：Apollo
密码：admin
