Also will show you, how we can manage or disable unwanted system services, such as Network Manager, which is no longer needed in-case you use a manual static IP configured on network scripts, Avahi-Daemon which is, also, not needed on a server and represents a seriously security gap, unless you installed the server on your Laptop and you want to instantly browse your network for other services, and on the final will present you Network Manager Text User Interface – nmtui, a system utility that can ease the job of editing your system network settings with advanced Interface configurations like creating Bond, Bridge, Team and VLAN Interfaces. Also be aware that most of configurations offered by editing system files should not be performed from a remote location using SSH service until you establish an continue and reliable network connection using a fixed IP address.
If, for example, our system will not be used as a mail service you can stop Postfix master daemon which runs on localhost and, also stop and disable other unwanted services using the following commands – the only service I advise not to stop or disable for now is SSH, if you need remote control over server. If you used Arch Linux then it should be a piece of cake to switch to systemd – although all init commands now are linked and pass-through systemd filter. Although it can be done smoothly without disrupting your connectivity and activate connection after reboot.
NOTE: After restart use the newly static IP address configured to perform remote login with SSH. Here you can add just the name of the system but it’s a good idea to append the .dot domain to. If you want to set static IP you can, also, use Network Manager Text User Interface as a facile alternative to actually edit network interfaces files, with a limited number of options that method has to offer, but make sure Network Manager service is enabled and started on your system. I'am a computer addicted guy, a fan of open source and linux based system software, have about 4 years experience with Linux distributions desktop, servers and bash scripting.
If it works with bootptoto=static then stick with this option as long as it does the job right! In my opinion you can use both approaches, manual editing NICs interfaces or configure static IP using NM or nmtui if you dont have a GUI. Also, the DNS settings need to stick to being setup in the resolv.conf file, not spread out in the ifcfg scripts. The reason I ask is because I only deal with servers (not desktops) and I’ve seen many times NetworkManger causing major network issues. Due to its Rolling Release model which embrace cutting age software Arch Linux was not designed and developed to run as a server to provide reliable network services because it requires extra time for maintenance, constants upgrades and sensible file configurations. But, still, because Arch Linux comes with a CD core installation with minimal software pre-installed, it can represent a solid base start up point to install most of the popular network services this days, this including LEMP or LAMP, Apache Web Server, Nginx, PHP, SQL databases, Samba, FTP servers, BIND and others, many of them being provided from Arch Linux official repositories and others from AUR. Note: By any means do not confuse MySQL root account with Linux system root account – they are two different things – not so different but they run on different levels. To verify MySQL security login to database using mysql -u root -p command syntax, provide your root password then leave database with exit; command.
Because we are using Nginx as a web server we need to install PHP-FPM backed module to communicate through Fast Common Gateway and change dynamic content generated by PHP scripts. Issue the following command line to install PHP-FPM service, then start daemon and verify status. Locate with [CTRL+W] keys and uncomment (remove ; at the line beginning) the following lines. On same file locate and edit open_basedir directive to resemble with the following included directories.


Although Arch Linux is not the most very-best suited system to run on production servers due to its community orientated rolling release model it can be a very fast and reliable source for small non-critical production environments. Answer: To set the ip-address, subnet mask and default gateway of your new VMware ESXi installation, follow the steps mentioned below. This will let you set the ip-address, subnet mask and default gateway of the VMware ESXi as shown below. Use this Contact Form to get in touch me with your comments, questions or suggestions about this site. Dynamic IP address is an IP address which is dynamically assigned to computer by DHCP Server and that may change over time. Now add nameservers according to the routers, We have added our nameservers according to router settings. After the tools have installed run ifconfig to get your Network Interfaces settings and status, and, then run netstat or lsof command to check what services are running by default on our server.
The netstat command output is pretty self-explanatory and shows a list of sockets associated with their running program name. You can, also, use old init commands to stop or disable services but since Red Hat now implements systemd process and service management, you should better get used to systemctl command and use it often. If you want to get a list of all started services run service command and for an exhaustive report use systemctl.
To manage services run systemctlcommand using the most important switches: start, stop, restart, reload, disable, enable, show, list-dependencies, is-enabled etc. Before starting editing Network Interface Card system files make sure that from now on and until you set static IP, you have physical or any other type of access to your server, because this step requires bringing down your network interface and connections. Use the next template to edit file and make sure that ONBOOT statement is set on YES , BOOTPROTO is set to static or none and don’t change HWADDR and UUID values provided by default. After finishing editing the file, close it and move to resolv.conf file if you want DNS servers enabled system wide.
Now Network Interface is configured with a static IP, the only thing remaining is to restart your network or reboot your system and use ifconfig or ip command to view IP address and test configuration using ping command. NetworkManager Text User Interface (TUI) tool, nmtui, is a RHEL intuitive tool which provides a text interface to configure networking by controlling Network Manager, which helps editing advanced network settings such as assign static IP addresses to Network Interfaces, activate or disable a connection, edit WI-FI connections, set your system hostname or create advanced Network interfaces like InfiniBand, bond, bridge, team or VLAN. To start Network Manager Text User Interface run nmtui command and use TAB or arrow keys to navigate through and press Enter to select an option. But for a better control and flexibility over your NICs you should go with manual configurations, without NM. After minimal Arch Linux core installation reboot your server, login with root account or equivalent administrative sudo account, and identify your system NICs device names using ip link command. To assign static network configurations we are going to use Netctl package to manage network connections. The next step is to start your network connection through netctl system tool and verify your system connectivity by issuing the following commands.


If you get an active green exit status you have successfully configured your Network Interface and it’s time to automatically enable it on system wide services. Now you can run ifconfig command to verify your Network Interfaces settings and check if everything is correctly displayed, then reboot your system to make sure everything is in place and properly configured. Before actually install LEMP stack we need to update system and then gain remote control to Arch Linux server. Because this tutorial is meant to be as a comprehensive guide I’ll will divide LEMP stack installation into small pieces, step by step. First install Nginx Web Server, then start it and verify its status by issuing the following commands. The next step is to provide a highly safe environment for MySQL databases by providing a password for MySQL root account, remove anonymous user account, remove test database and root accounts that are accessible from outside localhost.
Then configure php.ini file to include necessary extensions needed by PhpMyAdmin application. If everything runs as intended the final step is to enable LEMP system wide with the following commands. You have installed and configured LEMP on Arch Linux and, now, you have a full dynamic interface to begin and develop web applications. I will be posting instruction guides, how-to, troubleshooting tips and tricks on Linux, database, hardware, security and web. Still I will present you the entire method and indicate the steps needed to be avoided in case you want to maintain your connectivity and test it afterwards.
If you go with manual without NM don’t forget to use NM_CONTROLLED=no and ONBOOT=yes parameters.
Also test your network by running a ping command against a domain name and also, install net-tools package (the most well-known feature of this package is ifconfig command which Arch developers considered to be kind of deprecated and replaced it with iproute2). As you probably know OpenSSH is the main candidate for this job so go ahead and install it, start SSH daemon and enable it system wide.
Issue the following command to install MySQL database server and choose MariaDB engine, then start and verify daemon status.
Run the following command to improve MySQL security, press [Enter] for current root account password, then answer Yes to all questions ( also setup your root account password).
Issue the next command to backup nginx.conf web server file configuration then replace it with the following content.
