1.環(huán)境說明

[omm@node1 bak]$ cat /etc/redhat-release
CentOS Linux release 7.6.1810 (Core)
[omm@node1 bak]$ lscpu
Architecture:          x86_64

2.檢查環(huán)境

systemctl disable firewalld.service
systemctl stop firewalld.service
setenforce=0
sed -i '/^SELINUX=/c'SELINUX=disabled /etc/selinux/config

3.安裝基礎(chǔ)包

yum install -y libaio-devel 
yum install -y bzip2 libaio-devel flex bison ncurses-devel glibc-devel libxml2-devel patch redhat-lsb-core unzip gcc gcc-c++ perl openssl-devel libffi-devel libtool zlib-devel

4.創(chuàng)建相關(guān)目錄，用戶，組

groupadd dbgrp -g 2000
useradd omm -g 2000 -u 2000
echo "Enmotech2021@" | passwd --stdin omm
mkdir -p /opt/software/mogdb/
chown -R omm:dbgrp /opt/

5.上傳上傳并解壓二進(jìn)制文件

6.配置環(huán)境變量

su - omm
echo "export GAUSSHOME=/opt/software/mogdb/"  >> /home/omm/.bashrc && \
echo "export PATH=\$GAUSSHOME/bin:\$PATH " >> /home/omm/.bashrc && \
echo "export LD_LIBRARY_PATH=\$GAUSSHOME/lib:\$LD_LIBRARY_PATH" >> /home/omm/.bashrc
source /home/omm/.bashrc

7.初始化數(shù)據(jù)庫

[omm@node1 ~]$ gs_initdb --pgdata=/opt/mogdb/data --nodename=primary --pwpasswd=Enmo@123 --encoding=UTF-8 --locale=en_US.UTF-8
The files belonging to this database system will be owned by user "omm".
This user must also own the server process.

The database cluster will be initialized with locale "en_US.UTF-8".
The default text search configuration will be set to "english".

creating directory /opt/mogdb/data ... ok
creating subdirectories ... ok
selecting default max_connections ... 100
selecting default shared_buffers ... 32MB
creating configuration files ... ok
Begin init undo subsystem meta.
[INIT UNDO] Init undo subsystem meta successfully.
.........
loading foreign-data wrapper for MOT access ... ok
loading security plugin ... ok
update system tables ... ok
creating snapshots catalog ... ok
vacuuming database template1 ... ok
copying template1 to template0 ... ok
copying template1 to postgres ... ok
freezing database template0 ... ok
freezing database template1 ... ok
freezing database postgres ... ok

WARNING: enabling "trust" authentication for local connections
You can change this by editing pg_hba.conf or using the option -A, or
--auth-local and --auth-host, the next time you run gs_initdb.

Success. You can now start the database server of single node using:

    mogdb -D /opt/mogdb/data --single_node
or
    gs_ctl start -D /opt/mogdb/data -Z single_node -l logfile

8.修改初始化參數(shù)

echo "port=26000" >> /opt/mogdb/data/postgresql.conf
echo "listen_addresses = '0.0.0.0'" >> /opt/mogdb/data/postgresql.conf
echo "password_encryption_type = 1" >> /opt/mogdb/data/postgresql.conf
echo "log_directory = 'pg_log'" >> /opt/mogdb/data/postgresql.conf
echo "remote_read_mode=non_authentication" >> /opt/mogdb/data/postgresql.conf
echo "host all all 0.0.0.0/0 md5" >> /opt/mogdb/data/pg_hba.conf

9.啟動數(shù)據(jù)庫

[omm@node1 ~]$ gs_ctl start -D /opt/mogdb/data
