Installing Asterisk on CentOS7 (step-by-step)
Shrink home volume size and extend root volume size (if needed):
umount /home
df -h # verify that /home is unmounted
parted -l # to find type of the home LV filesystem (fxs in my case)
lvremove /dev/centos/home # remove LV from the VG
lvcreate -L 5G -n home centos
mkfs.xfs /dev/mapper/centos-home
mount -a
lvs
lsblk
df -h
lvextend -l +100%FREE /dev/centos/root
lvextend -l +100%FREE /dev/centos/root
xfs_growfs /dev/centos/root
df -h
lsblk
lvs
Setup networking:
systemctl stop NetworkManager
systemctl disable NetworkManager
chkconfig network on
systemctl start network
vi /etc/sysconfig/network-scripts/ifcfg-eth0 # assign IPADDR / PREFIX / GATEWAY / DNS1 / DNS2
vi /etc/sysconfig/network and add below two lines:
NETWORKING=yes
NOZEROCONF=true
systemctl restart network
Disable SELinux:
vi /etc/sysconfig/selinuix and change:
SELINUX=enabled to SELINUX=disabled
Setup NTP:
yum install -y ntp && ntpdate pool.ntp.org && chkconfig ntpd && service ntpd start
systemctl enable ntpd.service
systemctl status ntpd.service
systemctl start ntpd.service
systemctl status ntpd.service
Preinstall steps:
adduser asteriskpbx && passwd asteriskpbx && yum install sudo && visudo # uncomment #%wheel ALL=(ALL) ALL line
vi /etc/group # add asteriskpbx to wheel group: wheel:x:10:root,asteriskpbx
usermod -L asteriskpbx #make asteriskpbx user nologin
Before Asterisk installation, install all prerequisite packages:
yum -y install make gcc gcc-c++ make subversion libxml2-devel ncurses-devel openssl-devel vim-enhanced man glibc-devel autoconf libnewt kernel-devel kernel-headers linux-headers openssl-devel zlib-devel libsrtp libsrtp-devel uuid libuuid-devel mariadb-server jansson-devel libsqlite3x libsqlite3x-devel epel-release.noarch bash-completion bash-completion-extras unixODBC unixODBC-devel libtool-ltdl libtool-ltdl-devel mysql-connector-odbc mlocate libiodbc
Initial setup MariaDB:
systemctl status mariadb
systemctl enable mariadb
systemctl start mariadb
systemctl status mariadb
/usr/bin/mysql_secure_installation
Asterisk Installation:
yum update -y
yum update -y
yum install wget -y
mkdir -p ~/src/asterisk/
cd src/asterisk/
wget http://downloads.asterisk.org/pub/telephony/asterisk/asterisk-13-current.tar.gz
tar -xzvf asterisk-13-current.tar.gz
cd asterisk-13.23.1/
If your system is 64 bit and you want PJSIP:
./configure --libdir=/usr/lib64 --with-pjproject-bundled
Otherwise:
./configure
menuselect/menuselect --list-options
make
make install
make samples
make config
safe_asterisk
systemctl status asterisk
make config
safe_asterisk
systemctl status asterisk
After install steps:
chown -R asteriskpbx:asteriskpbx /usr/lib/asterisk/
chown -R asteriskpbx:asteriskpbx /usr/lib64/asterisk/
chown -R asteriskpbx:asteriskpbx /var/lib/asterisk
chown -R asteriskpbx:asteriskpbx /var/spool/asterisk/
chown -R asteriskpbx:asteriskpbx /var/log/asterisk/
chown -R asteriskpbx:asteriskpbx /var/run/asterisk/
chown -R asteriskpbx:asteriskpbx /usr/sbin/ast
chown -R asteriskpbx:asteriskpbx /usr/sbin/asterisk
chown -R asteriskpbx:asteriskpbx /var/log/asterisk
asterisk -r
exit
If want - load modules needed for PJSIP
