Building Redis from source on Ubuntu server 18.04

After downloading redis source and attempting to make on Ubuntu server 28.04, it looks like I’ve got some dependencies missing:

kev@ubuntu18-redis1:~/redis/redis-4.0.11$ make

cd src && make all

make[1]: Entering directory '/home/kev/redis/redis-4.0.11/src'

    CC Makefile.dep

    CC adlist.o

In file included from adlist.c:34:0:

zmalloc.h:50:10: fatal error: jemalloc/jemalloc.h: No such file or directory

 #include <jemalloc/jemalloc.h>

          ^~~~~~~~~~~~~~~~~~~~~

compilation terminated.

I found an identical post about this issue, with not building the dependencies. To fix:

cd deps
make hiredis jemalloc linenoise lua geohash-int
cd ..
make
sudo make install

That resulted in a clean install, ready to start redis-server !

Installing RabbitMQ rpm on RHEL 5.11

Rough notes for installing RabbitMQ on RHEL5.11.

Install the EPEL repo (not sure if this is needed for the RPM install or not):

curl -O http://archives.fedoraproject.org/pub/archive/epel/5/x86_64/epel-release-5-4.noarch.rpm
rpm -ivh epel-release-5-4.noarch.rpm 
yum update

Install the erlang dependency (from answer here):

wget -O /etc/yum.repos.d/epel-erlang.repo http://repos.fedorapeople.org/repos/peter/erlang/epel-erlang.repo
yum install erlang

Download the noarch version of RabbitMQ:

wget -O http://www.rabbitmq.com/releases/rabbitmq-server/v3.1.1/rabbitmq-server-3.1.1-1.noarch.rpm

Note on my initial install of RHEL 5.11 I could’t wget or curl to any https based sites, as I’d get SSL connection/certificate errors. I downloaded the rpm on another machine and scp’d it up to my server.

Install the rpm:

rpm -i rabbitmq-server-3.1.1-1.noarch.rpm

Enable the admin console:

rabbitmq-plugins enable rabbitmq_management

Delete the default guest user:

rabbitmqctl delete_user guest

Create a new admin user and add to the admin group:

rabbitmqctl add_user newuserid password
rabbitmqctl set_user_tags admin administrator

Start/stop/restart the server:

/sbin/service rabbitmq-server start
/sbin/service rabbitmq-server stop
/sbin/service rabbitmq-server restart

Additional notes:

I tried the generic Linux version wouldn’t start up for me, it gave this error, so found a working RPM above instead:

{"init terminating in do_boot",{undef,[{rabbit_prelaunch,start,[]},{init,start_it,1},{init,start_em,1}]}}

init terminating in do_boot ()

WordPress error uploading photos on nginx: “client intended to send too large body”

Attempting to upload some new photos between around 3 to 5MB, the majority of the uploads failed, and this error was occurring repeatedly in my nginx error.log:

2018/08/06 07:18:37 [error] 43#0: *5 client intended to send too large body: 3125530 bytes

Based on this tip from here, the solution was to increase the default POST body size config with this setting in my nginx.conf:

client_max_body_size 5M;

Increasing VMware ESXi guest desktop resolution for Ubuntu 14.04

By default, my Ubuntu 14.04 desktop guest running under VMware ESXi has a maximum resolution of 1360×768 when accessed with the Remote Client, which although usable is not great on my MacBook Pro:

In the guest settings for my Ubuntu guest, I have rather limited graphics settings:

I tried bumping up the memory and see if that opens up some additional settings but that didn’t change anything, although for higher resolutions it’s most likely I would need more gpu memory, but that’s not the issue with the limited settings here.

Searching for ‘ESXi linux guest maximum resolution’ I found this article:

https://communities.vmware.com/thread/527747

which suggests to install a ‘desktop’ version of the open-vm-tools:

sudo apt-get install open-vm-tools-desktop

Let’s try that. After a reboot, now we’ve got higher resolutions! Awesome!
