I want to use tmux on rhel 7. I do not have root rights on this machine, so I build it from sources by following the procedure here: https://jdhao.github.io/2018/10/16/tmux_build_without_root_priviledge/.
I have built and installed locally libevent 2.1.8, ncurses 6.1 and tmux 2.8. They are all installed in ~/local.
When I launch tmux, it does not start. the message I get is:
[exited]
I started again with the option -vv and I get the logs.
On server side, I get:

The only thing I can see is that the client cannot connect the socket. I did not notice any error on server side.
I would know to understand what prevents tmux from starting normally.
A detailed analysis showed that the default shell used by tmux was exiting with an error on my environment.
I solved issue by forcing the use of another shell. I put this in .tmux.conf: set-option -g default-shell /bin/zsh.

I've installed ceph cluster in K8S using Rook, the service is running fine and PV/PVC is working as expected.
I was able to login to the dashboard once, but after a while the password is incorrect.
I used the command to display the password but it is still incorrect.
kubectl -n kubernetes-dashboard get secret $(kubectl -n kubernetes-dashboard get sa/admin-user -o jsonpath="{.secrets[0].name}") -o go-template="{{.data.token | base64decode}}"
No obvious error message from the pod

It seems like one can use the cephadm command to reset the password, but how can I login to the pod as a root user?
ceph dashboard ac-user-set-password USERNAME PASSWORD
This cephadm command can't be executed as non-root user:
ubuntu#:~$ k exec -it rook-ceph-tools-7884798859-7vcnz -n rook-ceph -- bash
[rook#rook-ceph-tools-7884798859-7vcnz /]$ cephadm
ERROR: cephadm should be run as root
[rook#rook-ceph-tools-7884798859-7vcnz /]$
I just ran "ceph dashboard ac-user-set-password admin -i 'File with password'" and my password changed.
I dont think cephadm works when execing into the pod.

And the wp-config is pointing to the correct database:
wp-config.php
-------------
// ** MySQL settings - You can get this info from your web host ** //
/** The name of the database for WordPress */
define( 'DB_NAME', 'wordpress' );
/** MySQL database username */
define( 'DB_USER', 'wordpress' );
/** MySQL database password */
define( 'DB_PASSWORD', 'wordpress' );
/** MySQL hostname */
define( 'DB_HOST', 'mariadb' );
/** Database Charset to use in creating database tables. */
define( 'DB_CHARSET', 'utf8' );
/** The Database Collate type. Don't change this if in doubt. */
define( 'DB_COLLATE', '' );
/** Filesystem access **/
define('FS_METHOD', 'direct');
With this setup, when I reach https://example.com I got a "File not found" error.
If I changed the ownership of the Wordpress files folder (/home/docker/sites/wordpress/html/) to 'docker' user I'm able to see the Wordpress app running, but and "Error establishing a database connection"

OK
To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system
PLEASE REMEMBER TO SET A PASSWORD FOR THE MariaDB root USER !
To do so, start the server, then issue the following command:
'/usr/bin/mysql_secure_installation'
which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.
See the MariaDB Knowledgebase at https://mariadb.com/kb or the
MySQL manual for more instructions.
You can start the MariaDB daemon with:
cd '/usr' ; /usr/bin/mysqld_safe --datadir='/config/databases'
You can test the MariaDB daemon with mysql-test-run.pl
cd '/usr/mysql-test' ; perl mysql-test-run.pl
Please report any problems at https://mariadb.org/jira

I think my problem is something with the PUID/PGID and users, but I can't get it work. Hope someone could point me in the right direction.
Thank you all in advance!
It's because of the complicated and so strict that your file permission configured. I think that you are trying to config your php-fpm to use user 1000 and group 998. But it is a wrong way because php-fpm also need to access to /usr/local/lib/php/* to load php extensions. Php-fpm has it owned mechanism to to switch to another user to serve client request while using root (or other power user to load PHP/system configurations). Because you are not using root to start php-fpm so it does not have permission to switch to another user, so you see the logs:
[05-Oct-2021 05:52:58] NOTICE: [pool www] 'user' directive is ignored when FPM is not running as root
[05-Oct-2021 05:52:58] NOTICE: [pool www] 'user' directive is ignored when FPM is not running as root
[05-Oct-2021 05:52:58] NOTICE: [pool www] 'group' directive is ignored when FPM is not running as root
[05-Oct-2021 05:52:58] NOTICE: [pool www] 'group' directive is ignored when FPM is not running as root
There are many ways to resolve your problems. If you still expect to use too strict the file permission like that, you will have to keep running php-fpm as root but on the php-fpm configuration (usually at etc/php-fpm.d/*.conf), you set user to 1000 and group to 998, so php-fpm will use that user and group to serve your client request and that user will be able to read your current source code files. However, I think you will have to make sure that user 1000 and 998 are existed in the image.
Secondly, I think your permission model is too strict and not necessary. I will grant +r for public to the source code files and start php-fpm as root (by default it will use www user to serve clients).
I'm kinda new on setting up a production machine and I don't get why I'm not seeing the default index page for nginx on my EC2 machine. It's installed and running on my server, but when I try to access, it keeps loading and shows nothing, keeps on a blank page. I'm trying to access through the public ip (35.160.22.104) and through public dns(ec2-35-160-22-104.us-west-2.compute.amazonaws.com). Both does the same. What I'm doing wrong?
UPDATE:
I realized that when restarting nginx service, it didn't showed the "ok" message. So I took a look at error.log:
[ 2016-12-12 17:16:11.2439 709/7f3eebc93780 age/Cor/CoreMain.cpp:967 ]: Passenger core shutdown finished

Anyway, it doesn't looks like an error, but a usual log.
UPDATE 2:
Nginx is running:
root 810 1 0 17:16 ? 00:00:00 nginx: master process /usr/sbin/nginx -g daemon on; master_process on;

ubuntu 853 32300 0 17:44 pts/0 00:00:00 grep --color=auto nginx
And when I try do curl localhost, it returns the HTML as expected!
UPDATE3:
When I run systemctl status nginx, I get the following error:
Dec 12 17:54:48 ip-172-31-40-156 systemd[1]: nginx.service: Failed to read PID from file /run/nginx.pid: Invalid argument
Trying to figure out what it is

Trying to get the home directory of running process.
For Linux, I learned that I could use /proc/PID/exe information, but I think there is no that information in other OS.
Assuming that there is no file information $PATH, can you let me know how I can get the home directory of the running process?
I just need to assume that OS utilities usage is very limited in OS, meaning that I should use very common command.
Condition:
No special utility such as lsof.
Added
The process I am referring is the process a 3rd-party application runs.
Thanks in advance.

Some system processes have no home directory, e.g., you may see /usr/sbin on Linux systems, or some other directory that several processes share.

POSIX ps shows the options of POSIX ps, implemented in these systems:
HPUX ps
Solaris ps
Linux ps
AIX ps
passwd(5) shows the file-format of /etc/passwd
OP amended question to indicate that the current directory (rather than home-directory) is wanted. Systems using a proc-filesystem can provide this information. Those are Solaris, AIX and Linux.
However, HPUX does not (see for example /proc on HP-UX?, which says the pstat system-call can be used). I do not see a possibility, reading its manual page, but the link below says pstat_getpathname will work.
AIX supports it, according to IBM documentation.
Look for the cwd "file" for the working directory of a given process in systems with a proc-filesystem.

I hope you can help me. I can not stand having to keep restarting my ec2 instance on Amazon.
I have two wordpress sites hosted there. My sites have always worked well until two months ago, one of them started having this problem. I tried all ways pack up, and the only solution was to reconfigure.
Now that all was right with the two. The second site started the same problem. I think Amazon is clowning me.
I am using a free micro instance. If anyone knows what the problem is, please help me!
Your issue will be the limited memory that is allocated to the T1 Micro instances in EC2. I'm assuming you are using ANI Linux in this case and if an alternate version of Linux is used then you may have different locations for your log and config files.
Make sure you are the root user.
Have a look at your MySQL logs in the following location:
/var/log/mysqld.log
If you see repeated instances of the following it's pretty certain that the 0.6GB of memory allocated to the micro instance is not cutting it.
150714 22:13:33 InnoDB: Initializing buffer pool, size = 12.0M
InnoDB: mmap(12877824 bytes) failed; errno 12
150714 22:13:33 InnoDB: Completed initialization of buffer pool
150714 22:13:33 InnoDB: Fatal error: cannot allocate memory for the buffer pool

150714 22:13:33 [ERROR] Unknown/unsupported storage engine: InnoDB

You will notice in the log excerpt above that my buffer pool size is set to 12MB. This can be configured by adding the line innodb_buffer_pool_size = 12M to your MySQL config file /etc/my.cnf.
A pretty good way to deal with InnoDB chewing up your memory is to create a swap file.
Start by checking the status of your memory:
free -m
You will most probably see that your swap is not doing much:
total used free shared buffers cached
Mem: 592 574 17 0 15 235
-/+ buffers/cache: 323 268
Swap: 0 0 0
To start ensure you are logged in as the root user and run the following command:
dd if=/dev/zero of=/swapfile bs=1M count=1024
Wait for a bit as the command is not verbose but you should see the following response after about 15 seconds when the process is complete:
1024+0 records in
1024+0 records out
1073741824 bytes (1.1 GB) copied, 31.505 s, 34.1 MB/s
Next set up the swapspace with:
mkswap /swapfile
Now set up the swap event:
swapon /swapfile
If you get a permissions response you can ignore it or address the swap file by changing the permissions to 600 with the chmod command.
chmod 600 /swapfile
Now add the following line to /etc/fstab to create the swap spaces on server start:
/swapfile swap swap defaults 0 0
Restart your MySQL instance:
service mysqld restart
Finally check to see if your swap file is working correctly with the free -m command.
You should see something like:
total used free shared buffers cached
Mem: 592 575 16 0 16 235
-/+ buffers/cache: 323 269
Swap: 1023 0 1023
Hope this helps.
