Magento Installation not getting completed

[deepak_sharma28]

I have tried the command below command to install 

/usr/bin/php -d memory_limit=-1 /usr/local/bin/composer create-project --repository-url=https://repo.magento.com/ magento/project-community-edition .

$ /usr/bin/php -d memory_limit=-1 /usr/local/bin/composer create-project --repository-url=https://repo.magento.com/ magento/project-community-edition .
Creating a "magento/project-community-edition" project at "./"

[InvalidArgumentException]
Project directory "/var/www/html/magento240/." is not empty.

create-project [-s|--stability STABILITY] [--prefer-source] [--prefer-dist] [--repository REPOSITORY] [--repository-url REPOSITORY-URL] [--add-repository] [--dev] [--no-dev] [--no-custom-installers] [--no-scripts] [--no-progress] [--no-secure-http] [--keep-vcs] [--remove-vcs] [--no-install] [--ignore-platform-reqs] [--] [<package>] [<directory>] [<version>]

Installing starts only after i manually delete the composer.json and .gitingore files.

If i dont clear the composer caches, it runs and "kills" in a minute.

$ composer create-project --repository-url =https://repo.magento.com/ magento/project-community-edition . Creating a "magento/project-community-edition" project at "./" Installing magento/project-community-edition (2.4.0) - Installing magento/project-community-edition (2.4.0): Downloading (100%) Created project in /var/www/html/magento240/. Loading composer repositories with package information Updating dependencies (including require-dev) Killed

if i clear the cache.

$ composer clear-cache

It clears the cache and shows

$ composer create-project --repository-url =https://repo.magento.com/ magento/project-community-edition .

Earlier I was getting a SSH timeout in 5 Minutes with "Putty Fatal Error. Network Error: Software caused connection abort",

so i changed the configurations in

/etc/ssh/sshd_config

added following lines

ClientAliveInterval 30
ClientAliveCountMax 5

Now my connection is getting timedout in 15-20-minutes but installation is stuck at

Loading composer repositories with package information Updating dependencies (including require-dev)

Parallelly is was monitoring the memory, so in initial 5-10 minutes it goes to

Max usage
---------------
$ free -m
total used free shared buffers cached
Mem: 985 926 59 0 2 75
-/+ buffers/cache: 848 137
Swap: 0 0 0

then after Max Usage it frees the memory as below

---------------
$ free -m
total used free shared buffers cached
Mem: 985 131 854 0 0 20
-/+ buffers/cache: 110 875
Swap: 0 0 0

but installation is still stuck at

Loading composer repositories with package information Updating dependencies (including require-dev)

and finally after 10 mintues after memory is free i get

"Putty Fatal Error. Network Error: Software caused connection abort" and the installation is aborted

Hi ,

I went thru prerequisites and since I have 1GB ram on AWS (aws.amazon.com/amazon-linux-ami/2018.03) its recommended to add the swap file. 

So I added 2 GB first to the swap and installation used all 1RAM+2 GB and was finally installation abort as its not able to allocated memory.

I again added swap file, this time 3 GB and the installation utilized 1RAM +3GB

$ sudo fallocate -l 3G /.swapfile

$ sudo chmod 600 /.swapfile

$ sudo mkswap /.swapfile

$ sudo swapon -s

$ sudo nano /etc/fstab

$ /.swapfile none swap sw 0 0

and the installation ran for 1hr 25 minutes. Finally the process utilized all my 4 GB and aborted finally by terminating my shh timeout.

Below are the Memory Details

------------------------------------------

$ free -m
                     total        used free shared buffers cached
Mem:            985         915  69        0         0            10
-/+ buffers/cache:        905  80
Swap:          3071       3020 51

I also got into the same problem..

What I did was uninstall composer with all it's dependencies

sudo apt-get remove --auto-remove composer

Purge composer to remove settings

sudo apt-get purge composer

Or you can perform both

sudo apt-get purge --auto-remove composer

 Then install composer again with the following command

curl -sS https://getcomposer.org/installer | sudo php -- --install-dir=/usr/local/bin --filename=composer

Hello,

This can cause PuTTY sessions to be unexpectedly closed by the firewall if no traffic is seen in the session for some time, which will trigger the error: “Network Error: Software Caused Connection Abort”.

To solve this issue, you can configure PuTTY to send null packets and TCP keepalives every few seconds. see below link:
