Extra manual steps for root sar crontab

Manually running quick-start-setup-pg-ora-demo-scripts.sh

First let's review this setup script:

[root@pg10centos7 ~]# cat /vagrant/quick-start-setup-pg-ora-demo-scripts.sh
su -c "cd ~;pwd;git clone https://github.com/dgapitts/pg-ora-demo-scripts.git;ls -l pg-ora-demo-scripts" -s /bin/sh postgres
cp /vagrant/quick-start-setup-pg-ora-demo-scripts.sql /tmp/quick-start-setup-pg-ora-demo-scripts.sql
cp /vagrant/pgpass /tmp/pgpass
su -c "psql postgres -f /tmp/quick-start-setup-pg-ora-demo-scripts.sql" -s /bin/sh postgres
su -c "cat /tmp/pgpass >> ~/.pgpass" -s /bin/sh postgres
su -c "chmod 600 ~/.pgpass" -s /bin/sh postgres
cp /vagrant/bashrc.append.txt /tmp/bashrc.append.txt
su -c "cat /tmp/bashrc.append.txt >> ~/.bash_profile" -s /bin/sh postgres

Now stepping through manually, first you need to setup an ssh-key for the postgres user and upload it to github:

cd ~
ssh-keygen
cat ~/.ssh/id_rsa.pub
<< copy results into your https://github.com/settings/profile - SSH >>

i.e. as per https://help.github.com/en/articles/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent

Next as root

[root@pg10centos7 ~]# su -c "cd ~;pwd;git clone https://github.com/dgapitts/pg-ora-demo-scripts.git;ls -l pg-ora-demo-scripts" -s /bin/sh postgres

NB1 Currently I can read but not execute the

interim solution to copy this local

-bash: /vagrant/update_alluser_passwords_from_changeme.sh: Permission denied

after running update password, switch the pg_hba.conf by running the following

cp /vagrant/pg_hba.conf /tmp/pg_hba.conf
su -c "cp -p /var/lib/pgsql/10/data/pg_hba.conf /var/lib/pgsql/10/data/pg_hba.conf.`date '+%Y%m%d-%H%M'`.bak" -s /bin/sh postgres
su -c "cat /tmp/pg_hba.conf > /var/lib/pgsql/10/data/pg_hba.conf" -s /bin/sh postgres
systemctl stop postgresql-10.service
systemctl start postgresql-10.service
