Issues istalling NGINX on Ubuntu 20.04

Question

Hello all,

I was trying to install NgInx in my droplet following this tutorial:

https://www.digitalocean.com/community/tutorials/how-to-install-nginx-on-ubuntu-20-04

When I arrived to Step 3, checking NGINX status, I figured out that it was stopped. Then, I tried to start it running:

systemctl start nginx

And I got the following error:

$ systemctl start nginx
==== AUTHENTICATING FOR org.freedesktop.systemd1.manage-units ===
Authentication is required to start 'nginx.service'.
Authenticating as: Maxi Sbrocca,,, (maxi)
Password: 
==== AUTHENTICATION COMPLETE ===
Job for nginx.service failed because the control process exited with error code.
See "systemctl status nginx.service" and "journalctl -xe" for details.

Running journalctl -xe to get further information, I see this:

...
-- The unit UNIT has successfully entered the 'dead' state.

Do anyone know how to solve this issue?

Thanks in advance

Hi @maxisbrocca , It’s very strange that you are missing this file. Have you made any changes or removed anything prior to starting the tutorial? Anyway, here is a copy of the said file which you can use # /etc/securetty: list of terminals on which root is allowed to login. # See securetty(5) and login(1). console # Local X displays (allows empty passwords with pam_unix's nullok_secure) :0 :0.0 :0.1 :1 :1.0 :1.1 :2 :2.0 :2.1 :3 :3.0 :3.1 #... # ========================================================== # # TTYs sorted by major number according to Documentation/devices.txt # # ========================================================== # Virtual consoles tty1 tty2 tty3 tty4 tty5 tty6 tty7 tty8 tty9 tty10 tty11 tty12 tty13 tty14 tty15 tty16 tty17 tty18 tty19 tty20 tty21 tty22 tty23 tty24 tty25 tty26 tty27 tty28 tty29 tty30 tty31 tty32 tty33 tty34 tty35 tty36 tty37 tty38 tty39 tty40 tty41 tty42 tty43 tty44 tty45 tty46 tty47 tty48 tty49 tty50 tty51 tty52 tty53 tty54 tty55 tty56 tty57 tty58 tty59 tty60 tty61 tty62 tty63 # UART serial ports ttyS0 ttyS1 ttyS2 ttyS3 ttyS4 ttyS5 #...ttyS191 # Serial Mux devices (Linux/PA-RISC only) ttyB0 ttyB1 #... # Chase serial card ttyH0 ttyH1 #... # Cyclades serial cards ttyC0 ttyC1 #...ttyC31 # Digiboard serial cards ttyD0 ttyD1 #... # Stallion serial cards ttyE0 ttyE1 #...ttyE255 # Specialix serial cards ttyX0 ttyX1 #... # Comtrol Rocketport serial cards ttyR0 ttyR1 #... # SDL RISCom serial cards ttyL0 ttyL1 #... # Hayes ESP serial card ttyP0 ttyP1 #... # Computone IntelliPort II serial card ttyF0 ttyF1 #...ttyF255 # Specialix IO8+ serial card ttyW0 ttyW1 #... # Comtrol VS-1000 serial controller ttyV0 ttyV1 #... # ISI serial card ttyM0 ttyM1 #... # Technology Concepts serial card ttyT0 ttyT1 #... # Specialix RIO serial card ttySR0 ttySR1 #...ttySR511 # Chase Research AT/PCI-Fast serial card ttyCH0 ttyCH1 #...ttyCH63 # Moxa Intellio serial card ttyMX0 ttyMX1 #...ttyMX127 # SmartIO serial card ttySI0 ttySI1 #... # USB dongles ttyUSB0 ttyUSB1 ttyUSB2 #... # LinkUp Systems L72xx UARTs ttyLU0 ttyLU1 ttyLU2 ttyLU3 # StrongARM builtin serial ports ttySA0 ttySA1 ttySA2 # SCI serial port (SuperH) ports and SC26xx serial ports ttySC0 ttySC1 ttySC2 ttySC3 ttySC4 ttySC5 ttySC6 ttySC7 ttySC8 ttySC9 # ARM "AMBA" serial ports ttyAM0 ttyAM1 ttyAM2 ttyAM3 ttyAM4 ttyAM5 ttyAM6 ttyAM7 ttyAM8 ttyAM9 ttyAM10 ttyAM11 ttyAM12 ttyAM13 ttyAM14 ttyAM15 # Embedded ARM AMBA PL011 ports (e.g. emulated by QEMU) ttyAMA0 ttyAMA1 ttyAMA2 ttyAMA3 # DataBooster serial ports ttyDB0 ttyDB1 ttyDB2 ttyDB3 ttyDB4 ttyDB5 ttyDB6 ttyDB7 # SGI Altix console ports ttySG0 # Motorola i.MX ports ttySMX0 ttySMX1 ttySMX2 # Marvell MPSC ports ttyMM0 ttyMM1 # PPC CPM (SCC or SMC) ports ttyCPM0 ttyCPM1 ttyCPM2 ttyCPM3 ttyCPM4 ttyCPM5 # Altix serial cards ttyIOC0 ttyIOC1 #...ttyIOC31 # NEC VR4100 series SIU ttyVR0 # NEC VR4100 series SSIU ttyVR1 # Altix ioc4 serial cards ttyIOC84 ttyIOC85 #...ttyIOC115 # Altix ioc3 serial cards ttySIOC0 ttySIOC1 #...ttySIOC31 # PPC PSC ports ttyPSC0 ttyPSC1 ttyPSC2 ttyPSC3 ttyPSC4 ttyPSC5 # ATMEL serial ports ttyAT0 ttyAT1 #...ttyAT15 # Hilscher netX serial port ttyNX0 ttyNX1 #...ttyNX15 # Xilinx uartlite - port ttyUL0 ttyUL1 ttyUL2 ttyUL3 # Xen virtual console - port 0 xvc0 # pmac_zilog - port ttyPZ0 ttyPZ1 ttyPZ2 ttyPZ3 # TX39/49 serial port ttyTX0 ttyTX1 ttyTX2 ttyTX3 ttyTX4 ttyTX5 ttyTX6 ttyTX7 # SC26xx serial ports (see SCI serial ports (SuperH)) # MAX3100 serial ports ttyMAX0 ttyMAX1 ttyMAX2 ttyMAX3 # OMAP serial ports ttyO0 ttyO1 ttyO2 ttyO3 # User space serial ports ttyU0 ttyU1 # A2232 serial card ttyY0 ttyY1 # IBM 3270 terminal Unix tty access 3270/tty1 3270/tty2 #... # IBM iSeries/pSeries virtual console hvc0 hvc1 #... #IBM pSeries console ports hvsi0 hvsi1 hvsi2 # Equinox SST multi-port serial boards ttyEQ0 ttyEQ1 #...ttyEQ1027 # ========================================================== # # Not in Documentation/Devices.txt # # ========================================================== # Embedded Freescale i.MX ports ttymxc0 ttymxc1 ttymxc2 ttymxc3 ttymxc4 ttymxc5 # LXC (Linux Containers) lxc/console lxc/tty1 lxc/tty2 lxc/tty3 lxc/tty4 # Serial Console for MIPS Swarm duart0 duart1 # s390 and s390x ports in LPAR mode ttysclp0 # ODROID XU4 serial console ttySAC0 ttySAC1 ttySAC2 ttySAC3
