I have got a question and hope that somebody can help me. I own a vServer on a OpenVZ basis (I hate the kernel limitation) and can't install Redis.

What do I do:

• Clean install Ubuntu 16.04. LTS minimal


• Login as root


• run: apt update
  


• run: apt upgrade
  

(I don't know if this is relevant, but this appears during the process:

Installing new version of config file /etc/systemd/system.conf ...
addgroup: The group `systemd-journal' already exists as a system
group. Exiting. [/usr/lib/tmpfiles.d/var.conf:14] Duplicate line for

many levels of symbolic links Failed to validate path /var/run/sudo:
Too many levels of symbolic links Failed to validate path
/var/run/sudo/ts: Too many levels of symbolic links (Reading database
... 16369 files and directories currently installed.)

• run: apt install redis-server
  

Problem appears:

After that I can't start Redis-Server (failed because a timeout was exceeded). What can I do to fix this problem? I saw many threads about redis in this forum, but the solutions didn't help me. Sorry for my bad english. Thanks in advance.

To fix your error: Install Redis as non-root user.

sudo apt-get update

sudo apt-get install build-essential tcl

Download and Extract the Source Code

cd /tmp

Now, download the latest stable version of Redis. This is always available at a stable download URL:

curl -O http://download.redis.io/redis-stable.tar.gz

Unpack the tarball by typing:

tar xzvf redis-stable.tar.gz

Move into the Redis source directory structure that was just extracted:

cd redis-stable

Build and Install Redis

Compiling dependencies:

cd deps

sudo make hiredis jemalloc linenoise lua geohash-int

cd ..

Compile the Redis binaries by typing:

make

After the binaries are compiled, run the test suite to make sure everything was built correctly. You can do this by typing:

make test

This will typically take a few minutes to run. Once it is complete, you can install the binaries onto the system by typing:

sudo make install

Begin by creating the redis user and group. This can be done in a single command by typing:

sudo adduser --system --group --no-create-home redis

Now, we can create the /var/lib/redis directory by typing:

sudo mkdir /var/lib/redis

We should give the redis user and group ownership over this directory:

sudo chown redis:redis /var/lib/redis

Adjust the permissions so that regular users cannot access this location:

sudo chmod 770 /var/lib/redis

Starting Redis

Start up the systemd service by typing:

sudo systemctl start redis

Check that the service had no errors by running:

sudo systemctl status redis
