安装部署MySQL数据库
# 更新yum源，11机器：
~]# vi /etc/yum.repos.d/MariaDB.repo
[mariadb]
name = MariaDB
baseurl = https://mirrors.ustc.edu.cn/mariadb/yum/10.1/centos7-amd64/
gpgkey=https://mirrors.ustc.edu.cn/mariadb/yum/RPM-GPG-KEY-MariaDB
gpgcheck=1
# 导入GPG-KEY
~]# rpm --import https://mirrors.ustc.edu.cn/mariadb/yum/RPM-GPG-KEY-MariaDB
~]# yum list mariadb --show-duplicates
# out: mariadb.x86_64
~]# yum makecache
# out:Metadata Cache Created
# 更新数据库版本
~]# yum list mariadb-server --show-duplicates
~]# yum install mariadb-server -y
# 编辑基础配置
# 增加部分内容
~] vi /etc/my.cnf.d/server.cnf
[mysqld]
character_set_server = utf8mb4
collation_server = utf8mb4_general_ci
init_connect = "SET NAMES 'utf8mb4'"


# 11机器，修改基础配置,并启动：
# 在改内容下增加，字符集
~]# vi /etc/my.cnf.d/mysql-clients.cnf
[mysql]
default-character-set = utf8mb4
~]# systemctl start mariadb


# 11机器，设置,mysql密码：
~]# mysqladmin -uroot password
# 这里是设置密码：123456
~]# mysql -uroot -p
# 这里是输入密码
none)]> \s
# 确定SERVER\DB\CLIENT\CONN 都是utf8


# 11机器：
none)]> show databases;
none)]> drop database test;
none)]> exit
# 查看数据库是否正常
~]# ps aux|grep mysql
~]# netstat luntp|grep 3306
~]# wget https://raw.githubusercontent.com/ctripcorp/apollo/1.5.1/scripts/db/migration/configdb/V1.0.0__initialization.sql -O apolloconfig.sql
~]# cat apolloconfig.sql
~]# mysql -uroot -p < apolloconfig.sql
# 输入密码
~] mysql -uroot -p
# 输密码
none)]> show databases;


# 11机器，创建其它权限用户而不是直接给root权限：
none)]> use ApolloConfigDB;
ApolloConfigDB]> show tables;
ApolloConfigDB]> grant INSERT,DELETE,UPDATE,SELECT on ApolloConfigDB.* to 'apolloconfig'@'10.4.7.%' identified by "123456";
ApolloConfigDB]> select user,host from mysql.user;


# 11机器,修改初始数据：
ApolloConfigDB]> show tables;
ApolloConfigDB]> select * from ServerConfig\G
ApolloConfigDB]> update ApolloConfigDB.ServerConfig set ServerConfig.Value="http://config.od.com/eureka" where ServerConfig.Key="eureka.service.url";
ApolloConfigDB]> select * from ServerConfig\G

原：

改后：

# 11机器，解析域名：
~]# vi /var/named/od.com.zone
serial 前滚一位
config             A    10.4.7.10
~]# systemctl restart named


# 21机器，测试下21机器能不能查到(11机器是肯定能查到的)：
~]# dig -t A config.od.com @192.168.0.2 +short
# out:10.4.7.10

Apollo官方文档

上述代码是从Apollo官网拉下来的，不过第7行多了一行APOLLO_CONFIG_SERVICE_NAME=$(hostname -i)

其中export JAVA_OPTS修改了下资源，改小了

# 应用资源配置清单，22机器：
~]# kubectl apply -f http://k8s-yaml.od.com/apollo-configservice/cm.yaml
~]# kubectl apply -f http://k8s-yaml.od.com/apollo-configservice/dp.yaml
~]# kubectl apply -f http://k8s-yaml.od.com/apollo-configservice/svc.yaml
~]# kubectl apply -f http://k8s-yaml.od.com/apollo-configservice/ingress.yaml

资源给的少，可能稍微慢了一些，点进去->点右上角的LOGS，日志有点多，记得点击右下角的翻页

浏览器访问config.od.com

鼠标对着起来的Apollo，可以看到右下角有网址

# 22机器，curl：
~]# curl http://172.7.22.5:8080/info
