ubuntu部署TimescaleDB

系统环境： ubuntu16.04

PostgreSQL 版本： 12

---

注意：TimescaleDB 需要PostgreSQL 11.4+或12.0+。不再支持PostgreSQL 9.6.3+和10.9+，并将在以后的版本中删除。

一. 部署TimescaleDB

1. Add PostgreSQL's third party repository to get the latest PostgreSQL packages

ubuntu@VM-0-12-ubuntu:~# sudo echo "deb http://apt.postgresql.org/pub/repos/apt/ $(lsb_release -c -s)-pgdg main" | sudo tee /etc/apt/sources.list.d/pgdg.list 
ubuntu@VM-0-12-ubuntu:~# sudo wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add - 
ubuntu@VM-0-12-ubuntu:~# sudo apt-get update

1. Add PPA

ubuntu@VM-0-12-ubuntu:~# sudo add-apt-repository ppa:timescale/timescaledb-ppa 
ubuntu@VM-0-12-ubuntu:~# sudo apt-get update 


1. Install appropriate package for PG version

ubuntu@VM-0-12-ubuntu:~# sudo apt install timescaledb-postgresql-12


1. Run 'timescaledb-tune' (installed as part of the
   
   timescaledb-tools package, a recommended dependency) to update your config settings for TimescaleDB

ubuntu@VM-0-12-ubuntu:~# sudo timescaledb-tune --quiet --yes
ubuntu@VM-0-12-ubuntu:~# sudo service postgresql restart


1. 为postgres用户设置密码

ubuntu@VM-0-12-ubuntu:~$ sudo -u postgres psql postgres
psql (12.2 (Ubuntu 12.2-2.pgdg16.04+1))
Type "help" for help.postgres=# \password postgres
Enter new password: #输入密码
Enter it again: #确认密码
postgres=# \q #退出

1. 修改登录权限设置

ubuntu@VM-0-12-ubuntu:~# sudo vim /etc/postgresql/12/main/pg_hba.conf
...
# Database administrative login by Unix domain socket
# local all postgres md5
local all postgres peer #peer 方式允许管理员账号通过socket连接，用-h 指定socket目录，(default: "/var/run/postgresql")# TYPE DATABASE USER ADDRESS METHOD# "local" is for Unix domain socket connections only
local all all peer# IPv4 local connections:
host all all 10.0.0.1/16 md5
host all all 127.0.0.1/32 md5
...ubuntu@VM-0-12-ubuntu:~# sudo vim /etc/postgresql/12/main/postgresql.conf
...
listen_addresses = '*' # what IP address(es) to listen on;
...


1. 登录测试

ubuntu@VM-0-12-ubuntu:~$ psql -h /var/run/postgresql -U postgres -W
Password: #输入密码
psql (12.2 (Ubuntu 12.2-2.pgdg16.04+1))
Type "help" for help.postgres=# \q

二. 安装pg_prometheus拓展

1. 安装postgresql-server-dev-12

ubuntu@VM-0-12-ubuntu:~# sudo apt install postgresql-server-dev-12


1. 下载并解压最新 pg_prometheus's release安装包 (v0.2.2) 并解压

ubuntu@VM-0-12-ubuntu:~# cd /usr/local/src/prometheus/ && \
sudo wget https://github.com/timescale/pg_prometheus/archive/0.2.2.tar.gz && \
sudo tar -xf 0.2.2.tar.gz && \
cd pg_prometheus-0.2.2


1. 编译

ubuntu@VM-0-12-ubuntu:/usr/local/src/prometheus/pg_prometheus-0.2.2# sudo make install


1. 编辑 postgresql.conf 加入pg_prometheus 扩展

ubuntu@VM-0-12-ubuntu:~# sudo vim /etc/postgresql/12/main/postgresql.conf
...
# - Shared Library Preloading -shared_preload_libraries = 'timescaledb,pg_prometheus' # (change requires restart)
...


1. 重启postgresql

ubuntu@VM-0-12-ubuntu:~# sudo service postgresql restart


1. 创建pg_prometheus拓展

ubuntu@VM-0-12-ubuntu:~# psql -h /var/run/postgresql -U postgres -W
Password:
psql (12.2 (Ubuntu 12.2-2.pgdg16.04+1))
Type "help" for help.postgres=# CREATE EXTENSION IF NOT EXISTS pg_prometheus;
CREATE EXTENSION
postgres=# \q
