0、升级mysql到5.6
1、停止服务。
停止ambari-server、所有ambari-agent
ambari-server stop ambari-agent stop
2、备份ambari 数据库。
mkdir -p /root/tmp/ambariUpgrate
mysqlhotcopy --user=ambari --password=gotop123 ambari /root/tmp/ambariUpgrate
3、备份配置文件。
cp /etc/ambari-server/conf/ambari.properties /root/tmp/ambariUpgrate
4、备份并解压安装包
tar -zxf ambari-2.4.1.0-centos6.tar.gz
5、更新ambari.repo
备份旧的ambari.repo
将新的ambari.repo文件添加到/etc/yum.repos.d/目录下,所有机器都添加
yum clean all
yum info ambari-server
确认新的配置生效
6、停止Ambari-Metrics
7、更新ambari-server
yum -y upgrade ambari-server
8、所有机器更新agent
yum -y upgrade ambari-agent
检查是否安装
rpm -qa | grep ambari-agent
9、设置mysql驱动
拷贝mysql-connector-java-5.1.37.jar到/usr/lib/ambari-server/目录下
cp /usr/share/java/mysql-connector-java-5.1.37.jar /usr/lib/ambari-server/
10、更新数据库
ambari-server upgrade
11、修改表的存储引擎
SELECT CONCAT('ALTER TABLE ',table_name,' ENGINE=InnoDB;') FROM information_schema.tables
WHERE table_schema='ambari' AND ENGINE='MyISAM';
12、启动server
ambari-server start
13、启动所有agent（我的机器自动启动）
ambari-agent start
14、若安装了hive则执行
设置hive存在的mysql库
jdbc:mysql://wp/hive?createDatabaseIfNotExist=true&characterEncoding=UTF-8
ambari-server setup --jdbc-db=mysql --jdbc-driver=/usr/share/java/mysql-connector-java-5.1.37.jar
15、更新ambari-Metrics
确保服务停止
在所有机器上执行
yum clean all
yum -y upgrade ambari-metrics-monitor ambari-metrics-hadoop-sink
在安装了collector的主机上执行
yum -y upgrade ambari-metrics-collector
16、在metrics-collector主机上安装Grafana
curl -u admin:admin -H "X-Requested-By:ambari" -i -X POST http://192.168.137.123:8080/api/v1/clusters/gotop/services/AMBARI_METRICS/components/METRICS_GRAFANA
curl -u admin:admin -H "X-Requested-By:ambari" -i -X POST -d '{"host_components":[{"HostRoles":{"component_name":"METRICS_GRAFANA"}}]}' http://192.168.137.123:8080/api/v1/clusters/gotop/hosts?Hosts/host_name=wp43
备注：host_name=必须是主机名称不能是ip地址
17、再次在ambari上的主机页面组件上re-install一下Grafana
Hosts > host.name > Re-install
18、配置Grafana密码
Services > Ambari Metrics > Configs 配置密码
vi /var/lib/ambari-agent/cache/common-services/HIVE/0.12.0.2.0/package/scripts/hive_metastore.py
import sys
reload(sys)
sys.setdefaultencoding('utf-8')
