corrupted or tampered with during downloading ???

Well, I guess it’s common now to see this when trying to install OS X. My example happened when I tried to install El Capitan, fresh (no upgrade) on a newly formatted SSD – and had me scratching my bean.

I got this:
This copy of the Install OS X El Capitan application can't be verified. It may have been corrupted or tampered with during downloading

People have identified the need to set the clock back via Terminal, right before you install the OS after boot-up.

I checked my time & it was spot on (although it thought I was on the Left Coast, which I’m not).

I COULD have ran the infamous date command (date MMDDHHmmYY), but elected not to.

I deleted the installer and downloaded El Capitan yet again. Guess what? It worked.

Here is what I’m thinking. If you download & set it aside for a while, you need to roll your clock back. If not, you’re good to go.

So if you don’t have the luxury of downloading the OS again, see what the time/date stamp shows up as and set the date back to a week later than that and you should be all set.

So, if you see this (for example):

But it’s April, 2016 now … run:
date 0401101016

Exit the Terminal App and try the install again.

Do you want to build a WordPress …… (site)?


Here’s a build-out on CentOS 7.2.

Install just the core, then add packages as needed – as you see below:

[root@wordpress-server ~]# yum update -y
[root@wordpress-server ~]# yum install bash-completion -y
[root@wordpress-server ~]# systemctl reboot

[root@wordpress-server ~]# yum install httpd php php-gd mariadb mariadb-server php-mysql rsync wget -y
[root@wordpress-server ~]# systemctl start httpd mariadb
[root@wordpress-server ~]# systemctl enable httpd mariadb

[root@wordpress-server ~]# firewall-cmd –add-service=http
[root@wordpress-server ~]# firewall-cmd –add-service=http –permanent

Set passwords for MySql / MariaDB:

[root@wordpress-server ~]# mysql_secure_installation

Set root password? [Y/n] Y
New password:
Re-enter new password:
Password updated successfully!

Remove anonymous users? [Y/n] Y
… Success!

Disallow root login remotely? [Y/n] n
… skipping.

Remove test database and access to it? [Y/n] Y
– Dropping test database…
… Success!
– Removing privileges on test database…
… Success!

Reload privilege tables now? [Y/n] Y
… Success!

[root@wordpress-server ~]# mysql -u root -p
Enter password:

MariaDB [(none)]> create database wp_site_1;
Query OK, 1 row affected (0.01 sec)

MariaDB [(none)]> create user wordpressadmin@localhost identified by ‘pass_from_above’;
Query OK, 0 rows affected (0.00 sec)

MariaDB [(none)]> grant all privileges on wp_site_1.* to wordpressadmin@localhost identified by ‘pass_from_above’;
Query OK, 0 rows affected (0.00 sec)

MariaDB [(none)]> flush privileges;
Query OK, 0 rows affected (0.00 sec)

MariaDB [(none)]> exit

[root@wordpress-server ~]# groupadd wp

[root@wordpress-server ~]# wget http://wordpress.org/latest.tar.gz

[root@wordpress-server html]# tar zxvf latest.tar.gz

in /var/www/html:
root@wordpress-server html]# mkdir site_1

Copy software to the new directory:
[root@wordpress-server ~]# rsync -aP /root/wordpress/ /var/www/html/site_1/

Fix ownership:
[root@wordpress-server html]# chown -R apache.wp *
drwxr-xr-x. 5 apache wp 4096 Feb 2 12:12 site_1

[root@wordpress-server site_1]# cp wp-config-sample.php wp-config.php

Edit wp-config.php file, then copy to the other site_ directories:
define('DB_NAME', 'wp_site_1');
define('DB_USER', 'wordpressadmin');
define('DB_PASSWORD', 'password_from_mysql_secure_installation');

[root@wordpress-server html]# chown -R apache.wp *

[root@wp-srv-001 html]# vi /etc/php.ini
change the line to this: upload_max_filesize = 25M

Add the following as the last line in /etc/httpd/conf/httpd.conf:
IncludeOptional sites-enabled/*.conf

in /etc/httpd, make these directories:
[root@wordpress-server httpd]# mkdir sites-available
[root@wordpress-server httpd]# mkdir sites-enabled

in sites-available, make config files for each domain:
[root@wordpress-server sites-available]# ll
total 12
-rw-r--r--. 1 root root 203 Feb 4 23:37 yourdomain.conf

The file should have:

DocumentRoot /var/www/html/site_1
ServerName www.yourdomain.com
ServerAlias yourdomain.com
ErrorLog logs/yourdomain_error.log


Create the following symlinks to the .conf files:
ln -s /etc/httpd/sites-available/yourdomain.conf /etc/httpd/sites-enabled/yourdomain.conf


[root@wordpress-server httpd]# apachectl restart

Go to your domains!
