Content:

CppBlog is a high performance blog engine based on CppCMS technology
## Requirements
Before you install CppBlog you need to install
- [CppCMS Framework](/wikipp/en/page/cppcms_1x_build) - version 0.999.0 and above
- [CppDB Library](/sql/cppdb)
- [Discount Markdown Library](http://www.pell.portland.or.us/~orc/Code/discount/)
- [ImageMagick](http://www.imagemagick.org/) or [GraphicsMagick](http://www.graphicsmagick.org) library
Optionally if you want to embed LaTeX formulas you may
need latex and dvigif programs in runtime.
## Installation of CppBlog
Download cppblog-X.Y.Z.tar.bz2 and extract it:
tar -xjvf cppblog-X.Y.Z.tar.gz
cd cppblog-X.Y.Z
If you are using trunk version:
svn co https://cppcms.svn.sourceforge.net/svnroot/cppcms/blog/trunk cppblog
svn co https://svn.code.sf.net/p/cppcms/code/blog/trunk cppblog
cd cppblog
and then create a build directory
mkdir build
Configure the cppblog build system
cmake ..
Or of you want to install to ordinary `/usr` path instead
of `/usr/local`
cmake -DCMAKE_INSTALL_PREFIX=/usr ..
Then run
make
And as super user
make install
## Configuration of the blog
I assume that you had installed the blog to /usr/local directory (default for configure script). Otherwise, you should update absolute paths given in this documentation
### Database
You can find DB configuration scripts under /usr/local/share/cppblog/sql directory, use them to create a database
- If you use MySQL:
First of all, create database, let's call it "blog".
create database blog;
create user 'username'@'localhost' identified by 'password';
grant all privileges on blog.* to 'username'@'localhost';
Then create all required tables running:
mysql -u username --password=secret blog <mysql.sql
- If you use Sqlite3
Create a database:
sqlite3 /var/blog/blog.db <sqlite3.sql
Make sure that /var/blog/ and /var/blog/blog.db is writable by the web server.
- If you use PostgreSQL
createdb blog
psql blog <postgresql.sql
### CppBlog configuration
Take a sample configuration file placed under /usr/local/share/cppblog/sample_config.js create a copy and edit it.
1. First create your new, unique private key for session management. Run
cppcms_make_key --hmac sha1
Update the private keys in the configuration file.
**REMEMBER THESE ARE YOUR PRIVATE KEYS, KEEP THEM IN SECRET**
2. Configure connection string under `blog.connection_string`. Don't forget to define `@pool_size` connection string property to enable connection pooling.
Refer to [CppDB manual](http://cppcms.com/sql/cppdb) for exact options.
3. Configure your web server according [this manual](/wikipp/en/page/cppcms_1x_tut_web_server_config).
Note, the cppblog media files installed into `/usr/local/share/cppblog/media`. Make sure that you have configured
valid alias to this location and the `blog.media`
has correct value assigned according to the location
of the files relatively the the web servers
document root.
4. Make sure that `localization.messages.messages` and `views.paths` points to correct path:
Locale dictionaries:
"localization" : {
"messages" : {
"messages" : [ "/usr/local/share/locale"]
Views path:
"views" : {
"paths" : [ "/usr/local/lib/cppblog" ],
5. Make sure you set the correct value for `blog.host` configuration option. It is important for correct RSS generation.
### Customization
You can select one of the two views "orangesky" or "contended". You can select it by setting `views.default_skin` option.
The blog language can be selected by setting required value for `localization.locales` option.
### First Run
Once you had setup the blog of first access you will be asked to create a user and setup a password, once you configured them, login
