分为两部分
一安装oceanbase服务
准备工作
mkdir -p /data/1 /data/log1
chown -R admin.admin /data/1 /data/log1/
偷偷说:其实这步我忘记执行,也没影响我安装
oceanbase程序是很占内存的在安装时我们要先下载好安装包:
然后放在能记住的位置
安装包怎么下载地址:https://www.oceanbase.com/softwarecenter
版本没什么好说的 选择适合自己的就行 4.0及以后的安装更为方便
选择你喜欢的方式解压
tar -zxvf {你的压缩包路径}
解压好就会有一个 oceanbase-all-in-one进去后有个bin目录,里面有准备好的install.sh脚本
然后 运行它
./install.sh
注意路径
出现上图就说明成功了
然后找一个能记住的地址写进去一个config文件
这个文件内容可以复制官网的
也可以复制我的
我把我的配置分享在下面

前期安装比较重要的参数就是
datafile_size: 8G # Size of the data file.
log_disk_size: 4G # The size of disk space used by the clog files.
这两个将决定你能不能安装成功
有个简单的运算方法
datafile_size + log_disk_size + 4 < 你系统剩余空间
可以使用
df -h
查看你自己的系统空间 系统空间时分区的 如:
看看你的区还有没有足够的空间
然后就可命令进行部署一个集群
obd cluster deploy obytt100 -c obytt100.yaml
如果不提醒你 系统空间不足 那就能安装成功
这就是安装成功的样子(obytt100 running)
然后可以进去看一下
obclient -h127.1 -P 2883 -uroot@sys#obytt100 -e "show databases"
第一次进会让你输入密码,这里直接回车就行了
第一部分安装就结束了
第二部分就是链接本地的navicat
第一次连的时候会提醒你密码错误,之前咱们已经在命令行进入oceanbase数据库了,先别退出
查看服务器里的初始数据库都是有什么
show databases;进入mysql数据库,user表就在mysql数据库里
use mysql;修改root的密码
ALTER USER root IDENTIFIED BY 'oceanbase';
直接修改就行了 然后再用navicat连上 完事。
