Scripting for automatization of Wordpress
1+
# Atomate Wordpress
2+
3+
# Scripts for automating tasks related to Wordpress
4+
5+
These **Bash scripts** automate some usual tasks working with **Wordpress**, and **Nginx**/**MariaDB** backend. The scripts are usefull on a clean Debian Jessie installation and surely they don't work on Ubuntu so far. It's advise to **not** install before running install script by first time an Apache or other HTTP server, unless they are listening at any port except port 80, so they could may cause conflicts with Nginx.
6+
7+
## Install one local instance
8+
9+
Install a Wordpress instance on local.
10+
11+
### Usage
12+
13+
First change mod permissions of file to execute script, then:
14+
15+
`./install_wordpress.sh`
16+
17+
### Parameters
18+
19+
Some parameters are needed. They must be defined in `/conf/config` file.
20+
21+
###### Domain for Wordpress
22+
`domain=`
23+
24+
###### Title for Wordpress
25+
`title=`
26+
27+
###### Mysql root password
28+
`mysql_root_pass=`
29+
30+
###### Install path (without final slash)
31+
`wp_path=`
32+
33+
###### Charset that will use Wordpress
34+
`wp_charset=`
35+
36+
##### Wordpress locales
37+
`wp_locale=`
38+
39+
###### Wordpress user with administration rights
40+
`wp_admin_user=`
41+
42+
###### Password for Wordpress administrator
43+
`wp_admin_password=`
44+
45+
###### Wordpress administrator email
46+
`wp_admin_email=``
47+
48+
###### Host of Mariadb
49+
`wp_db_host=``
50+
51+
###### Database user for Wordpress
52+
`wp_db_user=`
53+
`
54+
###### Database user for Wordpress password
55+
`wp_db_password=`
56+
`
57+
###### Name of database for Wordpress
58+
`wp_db_name=`
59+
60+
###### User for wp cli. It's needed to execute wp cli.
61+
`wpcli_user=`
62+
63+
64+
## Uninstall one local instance
65+
66+
Uninstall local Wordpress installed with the **above** script. It's more than probable that script weren't work in other cases.
67+
68+
#### Usage
69+
70+
Simply:
71+
72+
`./uninstall_wordpress.sh yourdomain.org`
73+
74+
Only a FQDN domain name is needed as parameter. Script takes the rest of parameters, such the database name, from `wp-config.php` and Nginx's available sites.
75+
76+
## Backup Wordpress
77+
78+
Backup database, files and Nginx's site configuration via SSH to a remote folder. A pair of SSH keys is highly recommended. If you need some help to use them, this [tutorial](https://debian-administration.org/article/530/SSH_with_authentication_key_instead_of_password) is a good first step.
79+
80+
### Usage
81+
82+
`./backup_wordpress.sh`
83+
84+
### Parameters
85+
86+

###### Remote user for SSH
91+
92+
`backup_user=`
93+
94+
###### Remote host (IP or domain name)
95+
`backup_host=`
96+
97+
###### Remote path where files will be stored
98+
`backup_remote_dir=`
99+
100+
101+
## Restore Wordpress
102+
103+
Restored a site backed with the previous script.
104+
105+
