Install Redis-Server on Ubuntu 16.04 LTS minimal

Question

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 path "/var/log", ignoring. Failed to validate path /var/run/sshd: Too 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.

Solution

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

Welcome! Run commands ls -lah /var/run/redis/redis-server.pid and ls -lah /var/run/redis/ then show returns for both here.

[Firehead]

ls: cannot access '/var/run/redis/redis-server.pid': No such file or directory

[Firehead]

total 0 | drwxrwsr-x 2 root root 40 . | rrwxr-xr-x 13 root root 440 ..

[mature]

try with root user run chmod -R 777 /var/run/redis/ then run redis server again.

[Firehead]

Now -rw-r--r-- 1 redis root 6 Nov 19 20:07 /var/run/redis/redis-server.pid

[Firehead]

And total 4.OK drwxrwsrwx 2 root root 60 . drwxr-xr-x 13 root root 440 .. -rw-r--r-- 1 redis root 6 redis-server.pid

As i see redis-server.pid is created. Redis still not work?

[Firehead]

still not working :(

[Firehead]

hmm, redis works when I install it before the first apt update && apt upgrade. So something is wrong within the upgrade

[Firehead]

When I upgrade after the install of redis, redis is still working. But when I send the reboot command, the server doesn't reboot anymore and I have to reinstall the image.

Hi @Firehead! Our Ubuntu 16.04 server automatically updated itself at 2018-11-20 04:00 CET, and SSH stopped to work. It could to be somewhat related to your issue as we run two Redis instances on that server. What have you done to get a connection to your server again? Do you have errors related to systemd-tmpfiles in your log files?

[Firehead]

make[1]: Entering directory '/tmp/redis-stable/src' CC Makefile.dep CC adlist.o In file included from adlist.c:34:0: zmalloc.h:50:31: fatal error: jemalloc/jemalloc.h: No such file or directory compilation terminated.

try run: cd deps sudo make hiredis jemalloc linenoise lua geohash-int cd .. sudo make install separately

[Firehead]

thanks, I will try this later, server refuses connection, don't know why :D

[Firehead]

that didn't work neither -- make test: [exception]: Executing test client: couldn't open socket: no buffer space available. couldn't open socket: no buffer space available...

[mature]

try run redis-cli in command-line to check installation.. Redis socket you may setup separately (this is another question related redis setup. Example: guides.wp-bullet.com/…)

[Firehead]

result is: Could not connect to Redis at 127.0.0.1:6379: Connection refused
