为什么按照官方文档在部署后无法启动

OceanBase 技术问题
#1

【 使用环境 】生产环境 or 测试环境
【 OB or 其他组件 】
【 使用版本 】oceanbsae 4.3.0
【问题描述】无法启动 通过systemctl status oceanbase 显示 daemon PID file not found。
【复现路径】完全按照官方文档进行。使用EXSI虚机部署，虚机使用镜像是Anolis8.6版本。
【附件及日志】

【SOP系列 22 】——故障诊断第一步(自助诊断和诊断信息收集)

#3

提供以下：
1、参考的文档链接
2、ps -ef | grep observer | grep -v grep 确认一下observer进程是否存在
3、提供一下observer.log 日志附件

#4

https://www.oceanbase.com/docs/common-oceanbase-database-cn-1000000000640297
使用的是“ 使用 systemd 部署 OceanBase 数据库”进行的安装。没有任何日志信息，甚至他都不能够创建run文件夹存放pid文件。
这是我的oceanbase.cnf文件内容 mysql_port=2881
rpc_port=2882
obshell_port=2886
root_pwd=""
redo_dir=/redo
data_dir=/data
datafile_size=2G
datafile_next=2G
datafile_maxsize=20G
cpu_count=16
memory_limit=10G
system_memory=5G
log_disk_size=13G
enable_syslog_wf=true
enable_syslog_recycle=true
max_syslog_file_count=4
__min_full_resource_pool_memory=1073741824

#5

datafile_size=2G
datafile_next=2G
datafile_maxsize=20G
cpu_count=16
memory_limit=10G
system_memory=5G
log_disk_size=13G
默认配置得嘛？

#6

oceanbase.cnf文件默认创建路径在/etc/下么

#7

memory_limit=6G
system_memory=1G 只修改了这两部分 这个是默认参数

#8

是的

#9

调整调整参数值 试试。

#10

这样找一下日志看看：find / -name “observer.log”，找到后将日志压缩上传一下。

另外确认一下部署启动后observer进程是否存在？

#11

memory_limit调大点试试

#12

文档中使用systemd 确实没有进程和日志。目前不知道原因，日志后续再看看上传。不过使用 文档中的命令行方式可以部署成功。

#13

应该不是内存问题 ，我做过多次部署 ，调整过最大10G

#14

obd得形式嘛？

#15

是的 obd方式部署的可以。

#16

如果还是失败，请提供一下 observer.log 日志看看。

#17

可能是这两个参数问题，我也遇到同样情况，改了这两个参数就好了

#18

检查一下在/etc/security/limits.d目录下是否有nofile.conf和nproc .conf文件，如果没有的话执行下面的语句
echo -e “* soft nofile 20000\n* hadr nofile 20000”>>/etc/security/limits.d/nofile.conf
echo -e “* soft nproc 120000\n* hadr nproc 120000”>>/etc/security/limits.d/nproc .conf
注意执行完上面的语句之后要退出当前会话才会生效，重新连接再执行相关的部署启动命令。
