关闭selinux

查看SELinux状态：

/usr/sbin/sestatus -v

所有主机均需关闭SELinux：

# vim /etc/selinux/config
将SELINUX=enforcing改为SELINUX=disabled

重启机器即可

reboot

修改为外部数据库

0、关闭cloudera-scm-server和cloudera-scm-server-db

# service cloudera-scm-server stop
# service cloudera-scm-server-db stop

1、修改db.properties

# vim /etc/cloudera-scm-server/db.properties

//注释掉原来的
com.cloudera.cmf.db.type=mysql
com.cloudera.cmf.db.host=localhost:3306
com.cloudera.cmf.db.name=scm
com.cloudera.cmf.db.user=root
com.cloudera.cmf.db.password=123456
com.cloudera.cmf.db.setupType=EXTERNA

2、在数据库中，创建数据库scm。
3、启动cm

# service cloudera-scm-server start

注意不用再启动cloudera-scm-server-db。

配置mysql-connector

cp mysql-connector-java-5.1.27.jar /usr/share/java/mysql-connector-java
cp mysql-connector-java-5.1.27.jar /usr/share/cmf/lib/mysql-connector-java

yum配置

yum.conf

/etc/yum.conf

[main]
cachedir=/var/cache/yum/$basearch/$releasever
keepcache=0
debuglevel=2
logfile=/var/log/yum.log
exactarch=1
obsoletes=1
gpgcheck=1
plugins=1
installonly_limit=5
bugtracker_url=http://bugs.centos.org/set_project.php?project_id=23&ref=http://bugs.centos.org/bug_report_page.php?category=yum
distroverpkg=centos-release


# 若安装了deltarpm,但是报错no presto metadata available for cloudera-manager。则添加下面的一行。
deltarpm=0

yum.repo.d

yum的配置源文件目录。

/etc/yum.repo.d/

当在执行yum命令时，若报错，

1. 在此目录中，找到相应源的配置文件，将enabled=0;
2. 检查相应源文件的配置是否正确(baseurlurl是否正确)
3. 检查相应的源是否好使，考虑是否更换源。
