    /bin/sed -i "s/username_here/$db_user/g" $install_dir/wp-config.php
    /bin/sed -i "s/password_here/$db_password/g" $install_dir/wp-config.php
    cat << EOF >> $install_dir/wp-config.php
    define('FS_METHOD', 'ftpext');
    define('FTP_BASE', '$install_dir');
    define('FTP_USER', 'apache');
    define('FTP_PASS', '$ftp_password');
    define('FTP_HOST', '');
    define('FTP_SSL', false);
    cat << EOF >> $install_dir/.htaccess
    # BEGIN WordPress
    <IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /
    RewriteRule ^index.php$ – [L]
    RewriteCond %{REQUEST_FILENAME} !-f

    grep -A50 'table_prefix' $install_dir/wp-config.php > /tmp/wp-tmp-config
    /bin/sed -i '/**#@/,/$p/d' $install_dir/wp-config.php
    /usr/bin/lynx --dump -width 200 https://api.wordpress.org/secret-key/1.1/salt/ >> $install_dir/wp-config.php
    /bin/cat /tmp/wp-tmp-config >> $install_dir/wp-config.php && rm /tmp/wp-tmp-config -f
    /usr/bin/mysql -u root -e "CREATE DATABASE $db_name"

    ######Display generated passwords to log file.
    echo "Database Name: " $db_name
    echo "Database User: " $db_user
    echo "Database Password: " $db_password
    echo "Mysql root password: " $mysqlrootpass
    echo "FTP Password: " $ftp_password

    You will not need, but can retrieve the database credentials by tailing the end of the /tmp/firstboot.log file after installation. It is also recommended to remove the /tmp/firstboot.log file upon installation. You will be able to access your installation at http://yourip.

    Note: This script is meant to run on CentOS 6. It is not guaranteed to work on CentOS 7.
