[Appendix] Gentoo USE:

The simple understanding of USE is as follows: a software includes not only the software itself, but also its components, such as documentation, plug-ins, and GUI support. USE is used to mark whether to install the software and install these components at the same time.

Temporary USE:USE = "-java" emerge seamonkey

USE flag color
RED: enable
Blue: "-" is included in the front, indicating disable.
Green: enable, but there is no use flag
Yellow: none in the previous version. use flag added to this version
Parentheses (): use flag disabled on your platform

Wait for installation (it takes a long time to install it ..)

The following prompt is displayed when the task is completed:

1. * If you have users and/or services that you wowould like to utilize
2. * Socket, you must add them to the 'Seconds s' system group:
3. * Usermod-a-G postgres <user>
4. *
5. * Before initializing the database, you may want to edit PG_INITDB_OPTS
6. * So that it contains your preferred locale in:
7. */Etc/conf. d/postgresql-9.3
8. *
9. * Then, execute the following command to setup the initial database
10. * Environment:
11. * Emerge -- config = dev-db/postgresql-server-9.3.3
12. Gt;> Auto-cleaning packages...

Follow the prompts to edit/etc/conf. d/postgresql-9.3 (you can directly use the default, do not make any changes, encountered problems and then change)

1. # Configuration file location
2. PGDATA = "/etc/postgresql-9.3 /"
4. # Data storage directory/to be created
5. DATA_DIR = "/var/lib/postgresql/9.3/data"
7. # Optional
8. PG_INITDB_OPTS = "-- locale = en_US.UTF-8"

Run: emerge -- config = dev-db/postgresql-server-9.3.3 as prompted

14. * Instead of 'pg _ ctl '.

Then, continue with the prompt when the last command is installed (You shocould use the '/etc/init. d/postgresql-9.3' script to run PostgreSQL ):

Start postgreSQL service:/etc/init. d/postgresql-9.3 start
