股票交易接口源码-GreenPlum分布式集群部署实战

????环境准备

✨1安装包下载

✨2IP及实例规划

192.168.6.12	mdw1	5432	Master host
192.168.6.13	mdw2	5432	Standby host
192.168.6.14	sdw1	主：6000-6001 镜像：7000-7001	segment host1，配置2个主实例+2个镜像实例
192.168.6.15	sdw2	主：6000-6001 镜像：7000-7001	segment host2，配置2个主实例+2个镜像实例

✨3操作系统

[root@jeames~]#cat/etc/centos-releaseCentOSLinuxrelease1810[root@jeames~]#free-mtotalusedfreesharedbuff/cacheavailableMem:37711593407112043365Swap:396703967

????安装前准备

✨1hostname设置

1个master+1个standbymaster，2个segment的集群示例，OS均为CentOS1810–设置host名，4个节点设置hostnamectlset-hostnamemdw1hostnamectlset-hostnamemdw2hostnamectlset-hostnamesdw1hostnamectlset-hostnamesdw2

在股票交易接口源码,greenplum中，习惯将Master机器叫做mdw，将Segment机器叫做sdw，dw的含义为DataWarehouse。注意：4个节点设置一致cat>>/etc/hosts<<“EOF”191612mdw1191613mdw2191614sdw1191615sdw2EOF

✨3创建用户

groupadd-g1530gpadminuseradd-g1530-u1530-m-d/home/gpadmin-s/bin/bashgpadminchown-Rgpadmin:gpadmin/home/gpadminecho“gpadmin:jeames”|chpasswd

✨4host文件创建

为所有节点创建一个all_hosts文件，包含所有节点主机名su-gpadminmkdir-p/home/gpadmin/conf/cat>/home/gpadmin/conf/all_hosts<<“EOF”mdw1mdw2sdw1sdw2EOF为所有节点创建一个seg_hosts文件，包含所有的SegmentHost的主机名su-gpadmincat>/home/gpadmin/conf/seg_hosts<<“EOF”sdw1sdw2EOF

✨5配置互信

集群ssh免密,做互信的配置，只在master节点191612操作生成秘钥对ssh-keygen-trsa分发公钥su-gpadminssh-copy-idgpadmin@mdw1ssh-copy-idgpadmin@mdw2ssh-copy-idgpadmin@sdw1ssh-copy-idgpadmin@sdw2

✨6关闭防火墙

每个节点机器root用户操作systemctlstatusfirewalldsystemctlstopfirewalldsystemctldisablefirewalld

✨7禁用selinux

cat /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=enforcing
# SELINUXTYPE= can take one of three values:
#     targeted - Targeted processes are protected,
#     minimum - Modification of targeted policy. Only selected processes are protected.
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted

sed -i "s#^SELINUX=.*#SELINUX=disabled#g"  /etc/selinux/config
注意：修改后记得重启

????安装GP

✨1安装依赖

##安装依赖包
yum install net-tools -y
yum install libcgroup-tools -y

yum install -y apr apr-util bash bzip2 curl krb5 libcurl libevent libxml2 libyaml 
zlib openldap openssh openssl openssl-libs perl readline rsync R sed tar zip krb5-devel

✨2安装rpm包

## 在所有节点操作，root用户操作

1.默认安装到/usr/local下
rpm -ivh open-source-股票交易接口源码,greenplum-db-6.24.3-rhel7-x86_64.rpm

2.赋权,修改该路径gpadmin操作权限
chown -R gpadmin:gpadmin /usr/local/greenplum*

✨4数据库初始化

????GP集群验证

若初始化成功，则GP自动启动，可以看到master节点上的5432已经在listen了，psql进入数据库，开始greenplum之旅。

[gpadmin@mdw1 ~]$ netstat -tulnp | grep 5432
