Add log rotation

[gene1wood]

Enable log rotation of openresty web server logs.

Create a file /etc/logrotate.d/openresty with contents

# Make sure to first set the selinux context on the directory and files otherwise logrotate won't work
# semanage fcontext --add --type var_log_t '/usr/local/openresty/nginx/logs(/.*)?'
# restorecon -Frvv /usr/local/openresty/nginx/logs

/usr/local/openresty/nginx/logs/access.log /usr/local/openresty/nginx/logs/error.log {
        daily
        missingok
        rotate 30
        compress
        delaycompress
        notifempty
        create 644 root root
        sharedscripts
        postrotate
                if [ -f /usr/local/openresty/nginx/logs/nginx.pid ]; then
                        kill -USR1 `cat /usr/local/openresty/nginx/logs/nginx.pid`
                fi
        endscript
}

Set the selinux policy and file contexts by running

semanage fcontext --add --type var_log_t '/usr/local/openresty/nginx/logs(/.*)?'
restorecon -Frvv /usr/local/openresty/nginx/logs

I've done this manually on the live server but it's not captured here in the infrastructure-as-code
