  • O FreePBX é uma das opções para gerenciar o moderno mecanismo de telefonia IP - Asterisk. Por mais que os integradores não gostem dessa "superestrutura", certamente é o líder das instalações de PBX IP.

    Desativando o SELINUX

    vim /etc/sysconfig/selinux

    Substitua SELINUX=enforcing

    para

    SELINUX=disabled

    Configurando Dependências

    root@asteriskhelp# rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

    root@asteriskhelp# yum install -y kernel-devel kernel-headers

    root@asteriskhelp# yum install -y e2fsprogs-devel keyutils-libs-devel krb5-devel libogg \
    libselinux-devel libsepol-devel libxml2-devel libtiff-devel gmp php-pear \ 
    php-gd php-mysql php-pdo php mbstring ncurses-devel \ 
    mysql-connector-odbc unixODBC unixODBC-devel \ 
    audiofile-devel libogg-devel openssl-devel zlib-devel \ 
    perl-DateManip sox git wget net-ferramentas psmisc \ 
    yum instalar -y gcc gcc-c ++ fazer gnutls-devel \ 
    libxml2-devel ncurses-devel subversion doxygen \ 
    texinfo curl-devel net-snmp-devel néon-devel \ 
    uuid-devel libuuid-devel sqlite-devel sqlite \ 
    speex-devel gsm-devel libtool libtool-ltdl libtool-ltdl-devel \ 
    libsrtp libsrtp-devel xmlstarlet
    

    Fazendo as atualizações do sistema

    root@asteriskhelp# yum install update -y

    Reinicie o servidor

    root@asteriskhelp# reboot

    Instalando o mysql (mariadb)

    root@asteriskhelp# yum -y instala mariadb-server mariadb mariadb-devel

    Habilitando mariadb na inicialização do sistema

    root@asteriskhelp# systemctl enable mariadb.service

    Iniciando o mariadb

    root@asteriskhelp# systemctl start mariadb.service

    Iniciando o configurador do Mysql

    root@asteriskhelp# mysql_secure_installation
    Set root password? [Y/n] y 
    New password:
    Re-enter new password:
    Password updated successfully! 
    Reloading privilege tables.. 
     ... Success!
     
    
    By default, a MariaDB installation has an anonymous user, allowing anyone 
    to log into MariaDB without having to have a user account created for 
    them.  This is intended only for testing, and to make the installation 
    go a bit smoother.  You should remove them before moving into a 
    production environment. 
    
    Remove anonymous users? [Y/n] y
    ... Success!
    
    Normally, root should only be allowed to connect from "localhost".  This 
    ensures that someone cannot guess at the root password from the network.
    
    Disallow root login remotely? [Y/n] n 
    ... skipping.
    
    By default, MariaDB comes with a database named "test" that anyone can
    access.  This is also intended only for testing, and should be removed
    before moving into a production environment.
    
    Remove test database and access to it? [Y/n] y
    - Dropping test database...
     ... Success!
     - Removing privileges on test database...
     ... Success!
    
    Reloading the privilege tables will ensure that all changes made so far
    will take effect immediately.
    
    Reload privilege tables now? [Y/n] y
    ... Success!
    
    Cleaning up...
    
    All done!  If you"ve completed all of the above steps, your MariaDB
    installation should now be secure.
    
    Thanks for using MariaDB!

    Instalar o asterisk a partir do usuario asterisk

    No arquivo /usr/sbin/safe_asterisk nós substituímos as linhas:

    ASTARGS="" para ASTARGS="-U asterisk"
    

    Crie um usuário do Asterisk e defina as permissões do usuário.

    root@asteriskhelp# useradd -m asterisk
    

    Definir as permissões de pasta necessárias para o usuário asterisk
    root@asteriskhelp# chown asterisk.asterisk /var/run/asterisk
    
    root@asteriskhelp# chown -R asterisk.asterisk /etc/asterisk
    
    root@asteriskhelp# chown -R asterisk.asterisk /var/{lib,log,spool}/asterisk
    
    root@asteriskhelp# chown -R asterisk.asterisk /usr/lib64/asterisk
    
    

    Configurar o servidor web httpd (Apache)

    No arquivo de configuração do servidor web /etc/httpd/conf/httpd.conf

    Nós especificamos o usuário asterisk nas diretivas Usuário e Grupo:
    root@asteriskhelp# user  asterisk 
    root@asteriskhelp# group asterisk
    Especifique todas as diretivas para substituir as configurações do arquivo .htaccess

    No arquivo de configuração do servidor web /etc/httpd/conf/httpd.conf

    date.timezone = America/Sao_Paulo
    upload_max_filesize = 120 milhões

    Reinicie o apache
    root@asteriskhelp# systemctl restart httpd
    
    root@asteriskhelp# systemctl enable httpd

    Alterar as configurações de conexão do banco de dados

    No arquivo installlib/installcommand.class.php, um array $settings está configurado, a chave dbpass, que é um array, e neste array para a chave padrão, configure o valor da sua senha atual para o usuário root se conectar ao banco de dados:

    "dbpass" => array (
    "default" => "* senha para o banco de dados *",
    "description" => "Senha do banco de dados"
