前言
本文主要介绍了关于CentOS中部署多节点Citus集群的相关内容,分享出来供大家参考学习,下面话不多说了,来一起看看详细的介绍吧。
1、在所有节点执行以下步骤
Step 01 添加Citus Repostory
?
| 1 2 | # Add Citus repository for package manager curl https: //install .citusdata.com /community/rpm .sh | sudo bash |
Step 02 安装Citus并且初始化DB
?
| 1 2 3 4 5 6 | # install PostgreSQL with Citus extension sudo yum install -y citus72_10 # initialize system database (using RHEL 6 vs 7 method as necessary) sudo service postgresql-10 initdb || sudo /usr/pgsql-10/bin/postgresql-10-setup initdb # preload citus extension echo "shared_preload_libraries = 'citus'" | sudo tee -a /var/lib/pgsql/10/data/postgresql .conf |
Step 03 配置postgresql.conf
?
| 1 | sudo vi /var/lib/pgsql/10/data/postgresql .conf |
?
| 1 2 | # Uncomment listen_addresses for the changes to take effect listen_addresses = '*' |
Step 04 配置pg_hba.conf
?
| 1 | sudo vi /var/lib/pgsql/10/data/pg_hba .conf |
?
| 1 2 3 4 | local all all peer local replication all peer host all all 192.168.99.1 /24 trust host all all 0.0.0.0 /0 md5 |
Step 05 配置防火墙
查看
?
| 1 | firewall-cmd --zone=public --query-port=5432 /tcp |
添加5432端口(–permanent永久生效,没有此参数重启后失效)
?
| 1 | firewall-cmd --zone=public --add-port=5432 /tcp --permanent |
重新载入
?
| 1 | firewall-cmd --reload |
Step 06 启动服务
?
| 1 2 3 4 | # start the db server sudo service postgresql-10 restart # and make it start automatically when computer does sudo chkconfig postgresql-10 on |
Step 07 给需要的数据库安装Citus扩展
?
| 1 | sudo -i -u postgres psql -c "CREATE EXTENSION citus;" |
Step 08 设置密码
?
| 1 2 3 | postgres= # \password postgres #给postgres用户设置密码 Enter new password: Enter it again: |
2、在coordinator节点额外执行以下步骤
Step 01 添加worker节点信息
添加worker节点的IP地址(或者DNS名称)和端口号到pg_dist_node表。
?
| 1 2 | sudo -i -u postgres psql -c "SELECT * from master_add_node('192.168.99.101', 5432);" sudo -i -u postgres psql -c "SELECT * from master_add_node('192.168.99.102', 5432);" |
Step 02 验证安装是否成功
?
| 1 | sudo -i -u postgres psql -c "SELECT * FROM master_get_active_worker_nodes();" |
Step 03 开始使用
?
| 1 | sudo -i -u postgres psql |
