The third day of getting started with NoSQL-outlining updates

First, the analysis Redis configuration file redis.conf

　　(Linux configuration more than coding)

　　1. Where is it?

　　Since I downloaded the installation in Root's home directory, the default installation location is:

　　Conf is here:

　　According to experience, the factory conf never change

　　We copied the Conf and we copied it to/root/myredis.

　Here centOS7 default is to open the location of the last left

The configuration file compares detailed introductory information, such as:

　　　　Units units-Case insensitive:

　　　Includes contains--similar to sub-module development under the configuration file divided into Spring-shiro,spring-context module introduced

　　　　General Universal

　　　　Factory default setting is no--set to Yes to enable it to run in the background as a daemon

　　　　Default process pipeline ID file--pid

Can not rely on PID to identify the virus process, PID only for a period of time to help you identify the same process

　　　　Port--Default 6379

　　　tcp-backlog511--Default Value 511

Tcp-backlog
Setting the TCP Backlog,backlog is actually a connection queue, the backlog queue sum = Three handshake queue not completed + three handshake queue completed.
In high-concurrency environments you need a high backlog value to avoid slow client connectivity issues. Note that the Linux kernel will reduce this value to the/proc/sys/net/core/somaxconn value, so you need to confirm the increase of somaxconn and tcp_max_syn_backlog two values
To achieve the desired effect.

　　　　Binding:--beginner stage, will be tied to the machine 127.0.0.1 can

　　timeout--expiration time, you can set the number of seconds after the session is not connected, the default 0 is not closed

　　　View network traffic Status

　　　　Log levels--similar levels to log4j

　　　　Log file name:--Can be empty

　　　Log Switch--default syslog-enabled No, default is off, if open, will start with Redis

　　　Configuration of the database:--default 16 libraries 0-15

　　　　Snapshotting Snapshot

　　　　Replication replication

　　　　Security safety

　　　　Startup is found without entering the password, it is considered to be installed on Linux, is a relatively safe place, so it is not necessary to enter the password:

access password viewing, setup, and cancellation

　　Enter Password verification: (auth+ password Authentication)

　　Cancel Password:

　Limits restrictions
