Gbase8a安装时常见问题

1.     Gcinstall.py(line 2669) -- SetSusEnv.py must be executed before cluster is installed, not executed nodes ...

需要在所有安装节点上都执行下这个脚本SetSysEnv.py，以root用户执行

# python SetSysEnv.py --dbaUser=gbase --installPrefix=/opt

/opt为gbase8a安装目录

2.     缺少依赖包compat-db47

yum install compat-db47

3.     没有权限，Permission denied

# chmod 777 /opt

4.     Gbase8a集群服务无法启动时，查看防火墙状态

# systemctl stop firewalld         (关闭防火墙)

# systemctl disable firewalld

Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.

Removed symlink /etc/systemd/system/basic.target.wants/firewalld.service.

# vim /etc/selinux/config      (编辑配置文件)

SELINUX=disabled

5.     ssh服务找不到Unit ssh.service could not be found.

$ sudo service ssh status

Unit ssh.service could not be found.

$ sudo ps -e|grep ssh

$ sudo apt install openssh-server

$ sudo service ssh status
