SSDB installation Deployment and Considerations Summary

SSDB is a high-performance NoSQL database developed by C + + language, supporting data structures such as Key-value, Key-hashmap, Key-zset (sorted set), which is ideal for storing hundreds of millions of-level lists, sorting tables and other collection data, which is Red is replacement and enhancement scenarios.

SSDB has a similar API to Redis, supporting clients including: PHP, C + +, Python, Java, Lua, Ruby,nodejs, etc.

SSDB is stable, the production environment used, has been widely used in many internet companies, such as 360, Topgame.

Objective:

This article records the steps I installed and tested, summarizes the documentation for IDEAWU and makes it easy to use later.

The SSDB configuration file uses a TAB to indicate indentation, no spaces, and no one. Default configuration reference: Ssdb.conf.

SSDB supports primary master, master-slave deployment, and after starting a background thread, the data from the library will be synchronized to the main library at the millisecond level. My SSDB installation package path is:/export/servers/ssdb-master
My SSDB working directory is:/USR/LOCAL/SSDB
Download and install:
$ wget--no-check-certificate Https://github.com/ideawu/ssdb/archive/master.zip
$ unzip Master
$ CD Ssdb-master
$ make
$ # will be installed in the/USR/LOCAL/SSDB directory or specify directory make install Prefix=/home/servers/ssdb
$ sudo make install
#以默认环境配置为例:
$ cd/usr/local/ssdb
# Start the main library, or you can customize the configuration file to start multiple instances
$./ssdb-server ssdb.conf
# Start, stop, restart
# $./ssdb-ins.sh Start/stop/restart ssdb.conf
# start as a background process
$./ssdb-server-d ssdb.conf
# start the Ssdb command line, under the installation package path, 8889 ports for the main library
$/export/servers/ssdb-master/tools/ssdb-cli-p 8889
# command line to connect the remote SSDB service
# $/export/servers/ssdb-master/tools/ssdb-cli-h 192.168.1.1-p 8889
# Stop Ssdb-server, the default is to manually stop the SSDB service
$ Kill ' cat./var/ssdb.pid '
# or first find the PID of the current SSDB process and then the lore
# $ Ps-ef|grep ' Ssdb '
# $ kill-9 6912
SSDB Installation

SSDB Installation Example Diagram

Installation package Description: SSDB work default directory:/usr/local/ssdb
Configuration file:/usr/local/ssdb/ssdb.conf
Data and instance configuration:/usr/local/ssdb/var/
Boot Start command:/etc/init.d/ssdb.sh
Start-up permissions: chmod ugo+x/etc/init.d/ssdb.sh
Default port: 8888

SSDB startup scripts (with OS self-booting):

So far, you need to manually manage the ssdb-server process and if you want to manage it automatically when the operating system starts and stops, follow the instructions below.

Assuming you have installed SSDB in the default/usr/local/ssdb directory, place the tools/ssdb.sh script under the installation package in the/ETC/INIT.D directory. Modify the/data/ssdb_data/test/ssdb.conf in/etc/init.d/ssdb.sh to the path of your SSDB profile, and if you have multiple ssdb instances, write them on one line, separated by spaces:
# each config file for one instance
Configs=/data/ssdb_data/test/ssdb.conf/data/ssdb_data/demo/ssdb.conf
Main master, Master and slave configuration:
Service port configuration for the current instance
Server
#ip: 127.0.0.1
port:8888
# Bind to public IP
ip:0.0.0.0
# Format:allow|deny:all|ip_prefix
# Multiple allows or Denys is supported
#deny: All
#allow: 127.0.0.1
#allow: 192.168
Subordinate
The following is an example of the main library ip:192.168.1.1
#server 1 (Master)
Replication
Slaveof:
#server 2 (from)
Replication
Slaveof:
Id:svc_1
# Sync|mirror, default is Sync
Type:sync
ip:192.168.1.1
port:8888
Master-Master (dual-master)
The following is an example of the main library ip:192.168.1.1/192.168.1.2
#server 1
Replication
Slaveof:
id:svc_2
# Sync|mirror, default is Sync
Type:mirror
ip:192.168.1.1
port:8889
#server 2
Replication
Slaveof:
Id:svc_1
# Sync|mirror, default is Sync
Type:mirror
ip:192.168.1.2
port:8888
Attention:
1, if there is an outage, power down, kernel panic and other system failures, you need to manually delete the SSDB PID file, if the tools/ssdb.sh/etc/init.d/restart after the automatic removal of PID;
2, the default configuration of the log files by volume separation, you need to write their own crontab for log compression and periodic cleanup;
3, the configuration of the IP is best 0.0.0.0, external access, if the 127.0.0.1 can only be native access.

Using the SSDB command-line client (SSDB-CLI)

SSDB's command line client SSDB-CLI can be used for daily housekeeping, including viewing the SSDB's run-line status (info), as well as doing things that the API does not, such as emptying the entire database. 1, running line SSDB-CLI
# Connect to 127.0.0.1:8888,
$/usr/local/ssdb/ssdb-cli-h 127.0.0.1-p 8888
You can enter the letter "H" and press ENTER to view the Help information.
2, the line KV operation
Ssdb 127.0.0.1:8888>get Key
Ssdb 127.0.0.1:8888>set Key 1
Ssdb 127.0.0.1:8888>del Key
3, the line HashMap operation
Ssdb 127.0.0.1:8888> hsize H
Ssdb 127.0.0.1:8888> hset H K1 vb
Ssdb 127.0.0.1:8888> hset H K2 VA
Ssdb 127.0.0.1:8888> hset H K3 VC
Ssdb 127.0.0.1:8888> hscan H "" "" 10
Ssdb 127.0.0.1:8888> hclear H
4, the line Zset operation
Ssdb 127.0.0.1:8888> zsize Z
Ssdb 127.0.0.1:8888> zset z K1 2
Ssdb 127.0.0.1:8888> Zset z K2 0
Ssdb 127.0.0.1:8888> zset z K3 1
Ssdb 127.0.0.1:8888> zscan z "" "" "" 10
Ssdb 127.0.0.1:8888> zclear Z
