Hoy realizaremos la instalacion de odoo 13 en una maquina virtual centos 8 minimal desde 0.
1. Verificamos si tenemos instalado DNF con el Siguiente comando.
sudo dnf update
2. Lo siguiente realizamos la instalacion de EPEL Repository
$ sudo dnf install epel-release
3. Lo siguiente es descargar e instalar todas las dependencias relacionadas para utilizar ODOO por mi parte se instalaron al rededor de 90 paquetes necesarios.
32. actualizacion de error hacer lo siguiente para agregar el rol al usuario odoo
500 internal server error (Linux)
OperationalError: FATAL: role "root" does not exist
You find this error in file : /var/log/postgrsql/postgrsql-10-main.log (on linux system)
The solution may be :
1- Open Terminal and enter => sudo su postgres 2- Enter password for postgres System user (if it is necessary) 3- createuser odoo -s 4- psql template1 5- alter role odoo with password 'yourpassword'; 6- \q 7- exit 8- service odoo restart
*The C programming language provides many standard library functions for file input and output. These functions make up the bulk of the C standard library header <stdio.h>.
The first thing you will notice is the first line of the file, the #include "stdio.h" line. This is very much like the #define the preprocessor , except that instead of a simple substitution, an entire file is read in at this point.
The system will find the file named "stdio.h" and read its entire contents in, replacing this statement.
Obviously then, the file named "stdio.h" must contain valid C source statements that can be compiled as part of a program.
This particular file is composed of several standard #defines to define some of the standard I/O operations.
The file is called a header file and you will find several different header files on the source disks that came with your C compiler.
Each of the header files has a specific purpose and any or all of them can be included in any program.
Your C compiler uses the double quote marks to indicate that the search for the "include" file will begin in the current directory, and if it not found there, the search will continue in the "include" directory as set up in the environment.
It also uses the "less than" and "greater than" signs to indicate that the file search should begin in the directory specified in the environment.
Most of the programs in this tutorial have the double quotes in the "include" statements. The next program uses the "<" and ">" to illustrate the usage.
Note that this will result is a slightly faster (but probably unnoticeable) compilation because the system will not bother to search the current directory.
C – stdio.h library functions
********All C inbuilt functions which are declared in stdio.h header file are given below.********
List of inbuilt C functions in stdio.h file:
printf() This function is used to print the character, string, float, integer, octal and hexadecimal values onto the output screen
scanf() This function is used to read a character, string, numeric data from keyboard.
getc() It reads character from file
gets() It reads line from keyboard
getchar() It reads character from keyboard
puts() It writes line to o/p screen
putchar() It writes a character to screen
clearerr() This function clears the error indicators
f open() All file handling functions are defined in stdio.h header file
f close() closes an opened file
getw() reads an integer from file
putw() writes an integer to file
f getc() reads a character from file
putc() writes a character to file
f putc() writes a character to file
f gets() reads string from a file, one line at a time
f puts() writes string to a file
f eof() finds end of file
f getchar reads a character from keyboard
f getc() reads a character from file
f printf() writes formatted data to a file
f scanf() reads formatted data from a file
f getchar reads a character from keyboard
f putchar writes a character from keyboard
f seek() moves file pointer position to given location
SEEK_SET moves file pointer position to the beginning of the file
SEEK_CUR moves file pointer position to given location
SEEK_END moves file pointer position to the end of file.
f tell() gives current position of file pointer
rewind() moves file pointer position to the beginning of the file
The FDA also shortened the time for booster shots from at least six months after completion of the initial series to at least five months, for everyone aged 12 and older.
WASHINGTON, Jan. 3 (Xinhua) -- The U.S. Food and Drug Administration (FDA) on Monday expanded the emergency use authorization for the Pfizer-BioNTech COVID-19 vaccine boosters to children ages 12 to 15.
The FDA also shortened the time for booster shots from at least six months after completion of the initial series to at least five months, for everyone aged 12 and older.
The agency has determined that the protective health benefits of a single booster dose of the Pfizer-BioNTech COVID-19 vaccine to provide continued protection against COVID-19 and the associated serious consequences outweigh the potential risks in individuals ages 12 to 15.
The agency said that it found "no new safety concerns" following a booster shot in young teenagers, and that there were no new reports of two types of heart inflammation called myocarditis or pericarditis linked to the boosters.
The decision came as the Omicron variant is spreading rapidly across the United States and has led to record high hospitalizations among younger people.
