[How-To]Install Nginx, PHP, MySQL (LEMP) and phpMyAdmin

[moonman]

The directory is created automatically when you install monkey, I made sure of that and tested on 3 devices of mine.
EDIT: OK, I know what the problem is. /run (and /var/run being a symlink to /run) is tmpfs so everytime you reboot its contents are lost. I'll just make it create the pid file under /run.

Yup... I did. Fixed now

thanks rty and moonman. I installed mariadb per the first post in this thread, and it went fine (on seagate dockstar). mariadb with innodb works great, but it does use so many resources for the dockstar, that I probably won't have it always running. idling, it keeps the cpu 5 and 15 minute parameters at ~.25 and idling mem usage on the dockstar is 32% for mysqld and ~17% for systemd-journal, with sshd, php-fpm, smbd, nmbd, etc. all < 3% of mem usage.

I already had nginx and php-fpm running. I realize that moving from innodb to myisam, and from nginx to monkey might be more efficient, but since I don't need to run mysqld all the time, I think it's best now that it's running stable (uptime is at a record 16 days!) I will just run mysql when needed, which leaves quite a bit of free resources, and a snappy nginx/php, samba, and sshd server.

rty, probably something in my my.cnf is causing the large mem usage, i ran the tuning scripts, and decreased, then increased memory sizes, but I am pleased with the way it is running. Here is my my.cnf. Thanks again, for the great step by step install in post 1 here.

# This is for a system with little memory (32M - 64M) where MariaDB plays
# an important part, or systems up to 128M where MariaDB is used together with
# other programs (such as a web server)
#
# MariaDB programs look for option files in a set of
# locations which depend on the deployment platform.
# You can copy this option file to one of those
# locations. For information about these locations, do:
# 'my_print_defaults --help' and see what is printed under
# Default options are read from the following files in the given order:

# In this file, you can use all long options that a program supports.
# If you want to know which options a program supports, run the program
# with the "--help" option.

# Replication Slave (comment out master section to use this)
#
# To configure this host as a replication slave, you can choose between
# two methods :
#
# 1) Use the CHANGE MASTER TO command (fully described in our manual) -
# the syntax is:
#
# CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
# MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
#
# where you replace <host>, <user>, <password> by quoted strings and
# <port> by the master's port number (3306 by default).
#
# Example:
#
# CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
# MASTER_USER='joe', MASTER_PASSWORD='secret';
#
# OR
#
# 2) Set the variables below. However, in case you choose this method, then
# start replication for the first time (even unsuccessfully, for example
# if you mistyped the password in master-password and the slave fails to
# connect), the slave will create a master.info file, and any later
# change in this file to the variables' values below will be ignored and
# overridden by the content of the master.info file, unless you shutdown
# the slave server, delete master.info and restart the slaver server.
# For that reason, you may want to leave the lines below untouched
# (commented) and instead use CHANGE MASTER TO (see above)
#
# required unique id between 2 and 2^32 - 1
# (and different from the master)
# defaults to 2 if master-host is set
# but will not function as a slave if omitted
#server-id = 2
#
# The replication master for this slave - required
#master-host = <hostname>
#
# The username the slave will use for authentication when connecting
# to the master - required
#master-user = <username>
#
# The password the slave will authenticate with when connecting to
# the master - required
#master-password = <password>

hmm, well the idle mem usage dropped by 4-5% in one day, with no changes, so maybe it will drop further. The only thing I was doing on the pogo lately was programming and a failed attempt at installing weberly, a php gallery plug-in, but it doesn't use mysql. Anyways, the way it is, is fine.

[tedm]

well, it was running for about a day, but won't restart. Tried reducing memory a bit in my.cnf, starting, stopping, restarting, it tries to start, but just can't, similar issue to this one: http://chakra-project.org/bbs/viewtopic.php?pid=66457

Tried myisam, it is something different going on, related to the link in the previous post.
