不安装obd的请示

部署规划

这次作业是OceanBase 集群三节点部署方法，通过中控机直接远程登录到 OceanBase 节点上部署启动 observer 和 obproxy 进程。

由于手上正好有7台物理机，所以在这个作业中会使用OBD直接部署为2:2:2架构的OceanBase集群。

  • 机器信息如下：

环境设置

内核参数修改

修改配置文件：vi /etc/sysctl.conf

添加以下内容

net.core.somaxconn = 2048
net.core.netdev_max_backlog = 10000
net.core.rmem_default = 16777216
net.core.wmem_default = 16777216
net.core.rmem_max = 16777216
net.core.wmem_max = 16777216

net.ipv4.tcp_max_syn_backlog = 16384
net.ipv4.tcp_fin_timeout = 15
net.ipv4.tcp_max_syn_backlog = 16384
net.ipv4.tcp_tw_reuse = 1
net.ipv4.tcp_tw_recycle = 1
net.ipv4.tcp_slow_start_after_idle=0

让配置生效

sysctl -p

会话变量修改

OceanBase 数据库的进程涉及的限制包括线程最大栈空间大小（Stack）、最大文件句柄数（Open Files）和 core 文件大小 （Core File Size）。

修改配置文件：vi /etc/security/limits.conf

  • 在全局级别修改。注意修改后，已经登录的会话需要退出重登录才生效。

将会话级别的最大栈空间大小设置为 unlimited，最大文件句柄数设置为 655350，Core 文件大小设置为 unlimited 。 修改 /etc/security/limits.conf 配置文件，如果已有设置值低于这个设置值

* soft nofile 655360
* hard nofile 655360
* soft nproc 655360
* hard nproc 655360
* soft core unlimited
* hard core unlimited
* soft stack unlimited
* hard stack unlimited

查看配置方法。退出当前会话，重新登录。执行以下命令，查看配置是否生效：

ulimit -a

  • 1

关闭 SELinux

修改 SELinux 配置文件中的 SELINUX 选项。 注意：必须使用注释中的三个值之一。如果写错了，机器重启后操作系统会报错起不来，那时候就只能进入单用户模式修改了。

修改配置文件：vi /etc/selinux/config

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=disabled

配置文件修改后只会重启主机后生效，还需要使用下面命令立即生效。

setenforce 0

  • 1

关闭防火墙

查看防火墙状态

systemctl status firewalld

  • 1

如果是 inactive 那就不用管。如果是 active，那就永久关闭

systemctl disable firewalld 
systemctl stop firewalld
systemctl status firewalld

  • 1
  • 2
  • 3

判断是否使用 ntpd同步时间。

systemctl status ntpd
Unit ntpd.service could not be found.

  • 1
  • 2

如果提示上面这个信息，表示没有使用 ntpd。 如果提示有 ntpd 服务，就卸载 ntpd 软件，检查chrony服务。

chrony服务检查

  • 查看时间同步活动

    chronyc activity

    • 1

  • 查看时间服务器

    chronyc sources

    • 1

  • 查看同步状态

    chronyc sources -v

    • 1

  • 校准时间服务器：

    chronyc tracking

    • 1

安装chrony服务

如果没有安装，可以采用 YUM 安装方法。您也可以下载相应的 RPM 包安装。

我的服务器已经安装，以下安装方法参考社区教程，仅供参考：

yum -y install chrony

  • 1

chrony 配置说明

chrony 服务守护进程名是 chronyd，chronyc 是用来监控 chronyd 性能和配置参数的命令行工具。 chrony 的主配置文件: /etc/chrony.conf 。配置方法如下：

vi /etc/chrony.conf

# server 后面跟时间同步服务器
# 使用pool.ntp.org 项目中的公共服务器。按 server 配置，理论上您想添加多少时间服务器都可以。
# 或者使用 阿里云的 ntp 服务器
# Please consider joining the pool (http://www.pool.ntp.org/join.html).
server ntp.cloud.aliyuncs.com minpoll 4 maxpoll 10 iburst
server ntp.aliyun.com minpoll 4 maxpoll 10 iburst
server ntp1.aliyun.com minpoll 4 maxpoll 10 iburst
server ntp1.cloud.aliyuncs.com minpoll 4 maxpoll 10 iburst
server ntp10.cloud.aliyuncs.com minpoll 4 maxpoll 10 iburst

# 如果是测试环境，没有时间同步服务器，那就选取一台配置为时间同步服务器。
# 如果选中的是本机，则取消下面 server 注释
#server 127.127.1.0

# 根据实际时间计算出服务器增减时间的比率，然后记录到一个文件中，在系统重启后为系统做出最佳时间补偿调整。
driftfile /var/lib/chrony/drift

# chronyd 根据需求减慢或加速时间调整，
# 在某些情况下系统时钟可能漂移过快，导致时间调整用时过长。
# 该指令强制 chronyd 调整时期，大于某个阀值时步进调整系统时钟。
# 只有在因 chronyd 启动时间超过指定的限制时（可使用负值来禁用限制）没有更多时钟更新时才生效。
makestep 1.0 3

# 将启用一个内核模式，在该模式中，系统时间每11分钟会拷贝到实时时钟（RTC）。
rtcsync

# Enable hardware timestamping on all interfaces that support it.
# 通过使用hwtimestamp指令启用硬件时间戳
#hwtimestamp eth0
#hwtimestamp eth1
#hwtimestamp *

# Increase the minimum number of selectable sources required to adjust
# the system clock.
#minsources 2

# 指定一台主机、子网，或者网络以允许或拒绝NTP连接到扮演时钟服务器的机器
#allow 192.168.0.0/16
#deny 192.168/16

# 即使没有同步到时间源，也要服务时间
local stratum 10

# 指定包含NTP验证密钥的文件。
#keyfile /etc/chrony.keys

# 指定日志文件的目录。
logdir /var/log/chrony



# Select which information is logged.
#log measurements statistics tracking

出现lost+found 就说明我们挂载成功了。

设置可以自动挂载（永久挂载）

检查当前挂载情况：

[root@localhost /]# cat /etc/fstab

后我们不用UUID，直接写清楚把这台设备的哪个分区挂载到哪个目录下：

输入 vim /etc/fstab,进入修改界面：

将/data/1和data/2进行填写

#

这个意思就是把这台机器的sda分区挂载到/data/1，sdb分区挂载到/data/2，默认我们改成0 0就行。

保存退出，然后执行mount -a指令（a指auto，意思是让它自动挂载）

[root@localhost /]# mount -a
[root@localhost /]# 

  • 1

然后就完成自动挂载了。

更改目录权限
[root@localhost /]# chown -R admin.admin /data/1 && chown -R admin.admin /data/2
[root@localhost /]#

安装 OBD 自动化部署软件

OBD 全称是 OceanBase Deployer，是 OceanBase 社区版的命令行下自动化部署软件。 根据中控机器能否连接公网，提供离线和在线两种安装方法，您可根据实际情况选择安装方式。我这里是内网环境，选择离线安装。

下载相关软件包

软件包可通过官网下载页进行自行下载。

下载后的软件包传输到中控机上指定目录中。

obproxy-3.2.0-1.el7.x86_64.rpm

  • 1

离线安装 OBD

在登录中控机，我这里使用了root用户进行安装。一般情况下应该是应用用户安装。可自行选择。

ob-deploy 软件默认安装在 /usr/obd 下。不同版本可能有点变化，您可通过下面命令查看位置。

[root@localhost 3.1.2_ce]# rpm -ivh ob-deploy-1.2.0-15.el7.x86_64.rpm
warning: ob-deploy-1.2.0-15.el7.x86_64.rpm: Header V4 RSA/SHA1 Signature, key ID e9b4a7aa: NOKEY

检查安装是否成功

后续可以使用应用用户，比如admin用户执行检查obd是否安装成功。

[admin@localhost 3.1.2_ce]$ obd cluster list
Local deploy is empty

  • 1
  • 2
查看.obd/目录
[admin@localhost 3.1.2_ce]$ ls ~/.obd/
cluster  lock  log  mirror  plugins  version

  • 1
  • 2
关于~/.obd目录创建问题

刚安装obd 后, 没有创建任何~/.obd, 是直到敲任何一个obd 命令后, 才创建的.

而且不直接创建~/.obd 的原因是, obd 可以在任何一个用户下运行, 因此不知道在哪个用户下建~/.obd

obd命令

可使用 -h 查看 obd 命令使用帮助。

[admin@localhost 3.1.2_ce]$ obd -h
Usage: obd <command> [options]

Available commands:

cluster        Deploy and manage a cluster.

mirror         Manage a component repository for OBD.

repo           Manage local repository for OBD.

test           Run test for a running deployment.

update         Update OBD.


Options:
  --version      show program's version number and exit
  -h, --help     Show help and exit.
  -v, --verbose  Activate verbose output.

将软件包加到离线仓库

删除远程仓库

使用下面命令:

注意 :下面命令需在部署运行 OBD 的操作系统用户下操作。这里是用户 admin 。

/bin/rm -rf ~/.obd/mirror/remote/OceanBase.repo

  • 使用下面命令将前面的软件包复制到本地仓库。

安装OceanBase集群

编辑部署yml文件

obd可以支持对yml参数多种多样的配置安装，其中对生产环境有autodeploy模式，可以自适应参数。我这里做性能测试，所以选择了autodeploy模式。

从官网下载模板文件后进行编辑。下载地址：https://github.com/oceanbase/obdeploy/blob/master/example/autodeploy/distributed-with-obproxy-example.yaml
