Centos 7 Asterisk 13.3.2 install with kernel 3.19.8 update

Centos 7 Asterisk 13.3.2 install with kernel 3.19.8 update

I am not going to cover basic OS install here, You should have your OS installed and able to reach the internet. I did the Desktop install as I will be using this for other purposes. If this is a production asterisk only system you should do a minimal install.

I logged in as root user via putty/ssh.

Get your system ready.

Install some prereqs

# cd /root
# contrib/scripts/install_prereq install

Turn off firewall and iptables if they are on.

# systemctl disable firewalld.service
# systemctl stop firewalld.service
# systemctl disable iptables.service
# systemctl stop iptables.service

Disable selinux if it is enforced.

# vi /etc/sysconfig/selinux
    SELINUX=disabled

reboot if you have changed these

# reboot

Install NTP and turn on of not already.

# yum -y install ntp*
# systemctl disable chronyd.service
# systemctl enable ntpd.service
# systemctl start ntpd.service
# ntpq -p
# date

Update system and reboot.

# yum -y update
# reboot

I update the kernel as this is new build an I like to use a good updated kernel when I start things out. This "could be" optional. I don't know. I have not tried this on another kernel.

Update kernel to latest 3.x (3.19.8).

Get required packages for the kernel update, and some for asterisk install.

# yum -y groupinstall "Development Tools"
# yum -y install ncurses-devel qt-devel hmaccalc zlib-devel binutils-devel elfutils-libelf-devel wget bc gzip uuid* libuuid-devel jansson* libxml2* sqlite* openssl*
# yum -y update

Now from /root directory download the kernel source.

# wget http://www.kernel.org/pub/linux/kernel/v3.0/linux-3.19.8.tar.gz

Unzip and extract the source file.

# gzip -d ./linux-3.19.8.tar.gz
# tar -xvf ./linux-3.19.8.tar -C /usr/src/

Now let’s go to our source directory and configure the new Kernel. I just left everything alone and saved the file before I exit the menu.

# cd /usr/src/linux-3.19.8/
# make menuconfig

Compile kernel.

# make

Now go get coffee or beer. The compile will take a bit.

Install kernel.

# make modules_install
# make install

When finished lets reboot and use the new kernel. This will not be the default selection in grub so after you reboot the machine you need to press enter when you see the grub menu. You will only have a few seconds so beware.

You must be at console for choosing the kernel at boot manually. After we set this to to default kernel in grub we can return to putty.

# reboot

On boot screen select the new kernel for boot. After the boot and login type:

# uname -r
3.19.8

Looks like I am on the new Kernel.

Now set new kernel for default boot. I also leave console and return to putty here.

Check menu entries in grub.

# grep ^menuentry /boot/grub2/grub.cfg | cut -d "'" -f2

CentOS Linux 7 (Core), with Linux 0-rescue-455229da2acf4d3b941fda6a689c779c

Check current default.

# grub2-editenv list
saved_entry=CentOS Linux (3.10.0-229.4.2.el7.x86_64) 7 (Core)

Set new default.

# grub2-set-default "CentOS Linux 7 (Core), with Linux 3.19.8"

Check new default.

# grub2-editenv list
saved_entry=CentOS Linux (3.19.8) 7 (Core)

Now reboot and make sure new kernel is set for default.

# reboot
# uname -r
3.19.8
