To install and configure a serial console on CentOS or RHEL v6.x, you need to make changes to the system’s GRUB configuration, as well as the \/etc\/securetty<\/code> and \/etc\/inittab<\/code> files. Here are the steps you need to follow:<\/p>\n

    \n
  1. Edit the GRUB configuration file:\n
    \n
    <\/div>\n
    sudo nano \/etc\/grub.conf
    \n<\/code><\/div>\n<\/div>\n<\/li>\n
  2. Add the following lines to the end of the kernel<\/code> line:\n
    \n
    <\/div>\n
    console<\/span>=ttyS0,115200n8
    \n<\/code><\/div>\n<\/div>\n<\/li>\n
  3. Configure the serial port in \/etc\/securetty<\/code>:\n
    \n
    sudo nano \/etc\/securetty
    \n<\/code><\/div>\n<\/div>\n<\/li>\n
  4. Add the following line to the end of the file:\n
    \n
    <\/div>\n
    ttyS0
    \n<\/code><\/div>\n<\/div>\n<\/li>\n
  5. Edit the \/etc\/inittab<\/code> file:\n
    \n
    <\/div>\n
    sudo nano \/etc\/inittab
    \n<\/code><\/div>\n<\/div>\n<\/li>\n
  6. Add the following line to the end of the file:\n
    \n
    <\/div>\n
    S0<\/span>:<\/span>2345<\/span>:respawn<\/span>:\/sbin\/agetty<\/span> ttyS0 115200<\/span> vt100-nav
    \n<\/code><\/div>\n<\/div>\n<\/li>\n
  7. Save the changes and restart the system:\n
    \n
    <\/div>\n
    sudo reboot
    \n<\/code><\/div>\n<\/div>\n<\/li>\n<\/ol>\n

    After the system reboots, you should be able to access the console through the serial port using a terminal program such as minicom<\/code> or screen<\/code>. To connect using minicom<\/code>, use the following command:<\/p>\n

    \n
    <\/div>\n
    sudo minicom -b 115200 -o -D \/dev\/ttyS0
    \n<\/code><\/div>\n<\/div>\n

    Note: The above steps assume that the serial port is connected to \/dev\/ttyS0<\/code>. If your system uses a different device file for the serial port, you’ll need to adjust the steps accordingly.<\/p>\n","protected":false},"excerpt":{"rendered":"
