ClustrixDB安装配置
前提条件
在安装ClustrixDB之前,需要:
- ClustrixDB安装程序和许可证密钥。
- 运行CentOS或RHEL 7.4的服务器(本地或云中)。
- 具有root或sudo特权来安装ClustrixDB。在安装过程中,您可以配置用户以运行和管理数据库进程。
准备Linux操作系统
安装包
sudo yum install bzip2 xz wget screen ntp ntpdate vim htop mdadm
如果是RHEL,修改repo file:
sudo yum-config-manager --enable rhui-REGION-rhel-server-optional
ClustrixDB要求将数据库文件存储在基于本地SSD的文件系统上,该文件系统与包含操作系统的根卷不同。该卷应配置RAID-0以获得最佳性能,并包括所有用于ClustrixDB的SSD。为了实现冗余,默认情况下,ClustrixDB已经写入了两个数据副本,因此,如果发生节点故障或磁盘故障,数据仍然可用,并且不需要更高的RAID卷类型,因为这可能会影响性能。Clustrix建议使用/ data的默认安装点来简化安装。
确保ntpd服务开启,防火墙关闭
shell> sudo systemctl enable ntpd
shell> sudo systemctl start ntpd
shell> sudo systemctl disable firewalld
shell> sudo systemctl stop firewalld
核实SElinux关闭状态
shell> sestatus
SELinux status: disabled
如果开启修改 /etc/sysconfig/selinux 中 SELINUX=disabled
然后执行:
shell> setenforce
SELinux status: disabled
配置用户
默认情况下,ClustrixDB安装程序将创建和配置这些用户。如果愿意,可以在安装之前创建这些用户,然后指示安装程序使用这些用户。
这些是与安装和操作ClustrixDB有关的Linux OS用户帐户:
Linux OS用户 |
描述
|
如何使用 |
---|---|---|
root |
root、 |
运行ClustrixDB软件的初始安装。可以通过授予另一个Linux用户的sudo特权间接运行安装。ClustrixDB的后续升级不需要root级权限。 |
clxd |
ClustrixDB守护程序 |
ClustrixDB进程以clxd Linux用户身份运行。这是一个守护程序帐户,因此管理员不应使用该帐户登录Linux。一个例外是在执行ClustrixDB升级时,升级以clxd Linux用户身份执行。 |
clxm |
ClustrixDB管理 |
管理员可以使用此Linux用户来使用ClustrixDB软件。通常将此用户配置为设置其环境,以方便使用ClustrixDB命令行工具。 |
安装ClustrixDB
在每个节点上安装ClustrixDB
以root用户或具有sudo特权的非root Linux用户身份登录到每个ClustrixDB节点。
下载ClustrixDB安装,然后解压缩并运行安装程序脚本:
shell> tar xvfj current_version .el7.tar.bz2
shell> cd current_version
shell> sudo ./clxnode_install.py
安装时候交互的填写内容:
0,内存计算为服务器内存的百分70%-75%
7, MySQL端口修改非3306
