Memory is cheap. I don't recall a server where I created swap partition or swap file. Memory is NOT cheap, not at all. It is if you own it. If you rent your hardware, yeah, it adds up. Even if I own it, throwing away 2-3GB of RAM makes no sense. Now, if I own it, I can easily assign 4GB of RAM then remove it once installed, by why? That's harder to script and still no benefit. It's a bad habit to see resources as cheap and so waste them just because you can. Extra memory doesn't improve performance, it hurts it (just the tiniest bit). And it's not free, if you always apply twice as much RAM as you use (or four times, here), that gets costly one way or another. Either you wasted money overspeccing in the beginning, or you are stuck buying more now.

If you install using the above method, it never tells you the random password assigned to your management interface. But no fear, there is a tool that sets that for you and is super, duper easy. cd /usr/local/lsws/admin/misc sh admpass.sh It is interactive. And voila.

@JaredBusch said in Deploying NodeBB 1.13 on CentOS 8 with MongoDB 4.2: You can only remove this line if you are going to host the reverse proxy on the same instance. No reverse proxy needed if you are going to just look at it locally without going over the network.

Turns out that there was a wildcard A record in DomainA2.com

The last time I set up Graylog I had to configured SELinux.

Very odd. I just looked. I'm not sure what you're talking about. The page clearly shows snaps, dnf, apt, pacman, eopgk, and pkg_add for OpenBSD. https://gohugo.io/getting-started/installing Completely different than what I got from the same link this morning. I went to that page, clicked on Linux, and they only showed Brewlinux, which isn't even the current name of the system. Way back machine shows it's been there since at least the 13th. https://web.archive.org/web/20191113183617/https://gohugo.io/getting-started/installing/ Very weird. I wonder if it was a cache somewhere? I definitely poked around this morning and Linuxbrew was the only thing that it had and had it from every link that I tried on their site.

Finally released!!

@Obsolesce said in UREs Strike InnoDB on MySQL: @scottalanmiller said in UREs Strike InnoDB on MySQL: @Pete-S said in UREs Strike InnoDB on MySQL: Step one is to remove the drives and clone them with dd or recovery tool to a new drive. You could probably recover 99.9% of the data - if you want. As you can guess from all of their previous issues, they don't want to pay for any recovery, they just want it magically fixed for free. They don't own any storage onto which to clone it, either. Then what is the point of any of it? It appears to have zero value to the business. I said that to them.

@DustinB3403 said in MySQL MariaDB password reset without knowing the password: Just still seems weird to have the password in plaintext on in a config file. has to be somewhere, how else can an application connect? Look at WordPress, for example, you have to enter the password into the application so that the application can connect to the database. Otherwise, the database would have to have no password protection at all or you'd need a human to log in and enter the password every time a database connection was needed (which is normally thousands of times a minute.)

@wrx7m said in Configure Nginx as Reverse Proxy for ScreenConnect to Enable Lets Encrypt: Less to that than I thought there would be. It's surprisingly simple and basic. It's really just passing one port to another, and using SSL. About the most basic setup you can have.

@FATeknollogee said in oVirt Host Choices for Production: @EddieJennings I would start by using oVirt Node (it's based on CentOS), it's the simplest, least hassled way of setting up. Yeah, they have their own Node deployer, I'd generally just use that.

So, easy fix, the ca_stag2 was a staging DB that was not needed and was not current. The whole thing appears to have corrupted. So I simply "moved" that entire directory to /tmp (just in case I had to put it back) and then MySQL could fire up.

@JaredBusch said in Wazuh Agent Install - CentOS: Why are you disabling agent updates? Wazuh doesn't understand how to maintain their own repository, so when OSSIM updates their stuff, it breaks Wazuh. It's silly, easily fixable, and I don't have the time to maintain the thing myself.

@scottalanmiller Sounds solid. The speed difference is dramatic. Thanks.

@black3dynamite said in Setting Up a Standard MySQL or MariaDB Database for an Application: @JaredBusch said in Setting Up a Standard MySQL or MariaDB Database for an Application: I like my approach to setting this up. Obviously, install MySQL/MariaDB first as noted above. Then do the following. This all needs done in the same SSH session, but otherwise things are simple. Choose once of these exports for your DB root password. The first one is for you to specify, the second generates a random one and echo's it back to you. # Specify your own password for MariaDB root user export DB_ROOT_PASS="somebigpasswordgoeshere" # Generate a random password for MariaDB root user export DB_ROOT_PASS="$(head /dev/urandom | tr -dc A-Za-z0-9 | head -c 30)" echo "This is your MariaDB root password: $DB_ROOT_PASS" Specify the application database name and application user name # Database user to use for application export DB_USER='yourusername' # Database name to use for application export DB_NAME='yourdatabasename' Generate or specify a random password for the database user # Specify your own password for the application's database user export DB_PASS="somebigpasswordgoeshere" # Generate a random password for the application's database user export DB_PASS="$(head /dev/urandom | tr -dc A-Za-z0-9 | head -c 30)" echo "This is your password for the application user: $DB_PASS" Then create the application database, use, and grant access. mysql -e "CREATE DATABASE $DB_NAME;" mysql -e "CREATE USER '$DB_USER'@'localhost' IDENTIFIED BY '$DB_PASS';" mysql -e "GRANT ALL ON $DB_NAME.* TO '$DB_USER'@'localhost';" mysql -e "FLUSH PRIVILEGES;" Finally, lock down the system without the interactive requirement of mysql_secure_installation # Secure MariaDB (this does what mysql_secure_installation performs without interaction) mysql -e "UPDATE mysql.user SET Password=PASSWORD('$DB_ROOT_PASS') WHERE User='root';" mysql -e "DELETE FROM mysql.user WHERE User='root' AND Host NOT IN ('localhost', '127.0.0.1', '::1');" mysql -e "DELETE FROM mysql.user WHERE User='';" # Beginning on some version of MariaDB after Fedora 29 was released, the test DB is no longer there by defualt. mysql -e "DROP DATABASE test;" mysql -e "FLUSH PRIVILEGES;" Your approach makes it easier to use as part of a script. It also generates random passwords, which I prefer.

@DustinB3403 said in Troubleshooting Help Requested: @wrx7m said in Troubleshooting Help Requested: VLANs? No, and this VM is on the same vlan as other VMs on the same host. PS I've restored this VM to a completely different hypervisor and the issue persists. So either its the VM or the gateway. Have you tried a different IP, or even power down this machine and assign the same IP to another host to see if it gets blocked? Is the restored VM using the same MAC address as the original or has the restored version got a reinitialised MAC? Do you have access to check the logs on the gateway / edge / router to see if it's blocking / intercepting / messing with your host

@Emad-R said in Installing MS SQL Server Express on CentOS: Et me guess it is much faster on Linux than on Windows server No idea, but it is one less Windows Server license needed. Also MS SQL Server Express works well for many tasks.

@JaredBusch I don't know if you ever finished up with this client, but for $1236 you can get a decent server that would work well. Add $99 if you wanted the 3 year warranty

@bnrstnr said in Deploying NodeBB 1.11.1 on CentOS 7 with MongoDB 4: What specific reasons for the CentOS recommendation here? Revisiting a little... Basically the three main Linux releases supported by MongoDB are CentOS, Ubuntu, and Debian. CentOS and Ubuntu here are mostly six of one. But CentOS 8 Stream I like a little more than the Ubuntu LTS options. We use Ubuntu a little more often than CentOS today, but in this case I feel that CentOS is slightly better for us. But really, all three options are perfectly fine. We just have to pick one.

So, circling back. How is the backup project going?
