Linux Redis Installation Deployment Operations Guide (i)

First,RedisInstallation Deployment

introduction of 1.1 and environment

System Environment: Red hatenterprise Linux Server Release 6.2 (Santiago)

kernel version: Linux zxt-02.com2.6.32-220.el6.x86_64 #1 SMP Wed Nov 9 08:03:13 EST. x86_64 x86_64 x86_64gnu/linux

software version: redis-3.0.5

Host Name: zxt-1.com

Host IP : 192.168.1.108

Install the required software environment:

1.2,Redisinstallation

Software:http://redis.io/download

System Environment Configuration:

$echo vm.overcommit_memory=1 >>/etc/sysctl.conf $echo 511>/proc/sys/net/core/somaxconn

Use numeric meanings:

0 indicates that the kernel will check for sufficient available memory to be used by the process, and if sufficient memory is available, the memory request is allowed; otherwise, the memory request fails and the error is returned to the application process.

1 , which means that the kernel allows all physical memory to be allocated regardless of the current state of memory.

2 that indicates that the kernel allows allocating more memory than the sum of all physical memory and swap space

Compiling the installation

$wget Http://redis.googlecode.com/files/redis-2.2.7.tar.gz$tar xzf redis-2.2.7.tar.gz$cp-r redis-3.0.5/usr/local/$ Ln-s/usr/local/redis-3.0.5//usr/local/redis$cd/usr/local/redis$make test$make$make Install $CP redis.conf/etc/

Parameter description:

When the make install command finishes executing, the executable is generated in the/usr/local/bin directory, respectively , Redis-server,redis-cli, Redis-benchmark, redis-check-aof ,redis-check-dump, and their functions are as follows:

Redis-server:daemon boot program for Redis server

REDIS-CLI:Redis Command-line Operations tool. You can also use telnet to manipulate it based on its plain text protocol.

Redis-benchmark:redis Performance test tool to test Redis Read and write performance under current system

Redis-check-aof: Data repair

Redis-check-dump: Check the export tool

1.3, modifyRedisconfiguration file

[[email protected] bin]# vim /etc/redis.conf daemonize yes                            //42 line      #是否以后台daemon方式运行, default is not run in the background pidfile/var/run/redis/ REDIS.PID //46      #redis的PID文件路径 (may not change according to personal preference) bind 192.168.1.108                 //69 Line       #绑定主机IP, the default value of 127.0.0.1 can not be changed, if it is run across machines, you need to change logfile/var/log/redis/redis.log   //108 line     #定义log文件位置, mode log information directed to stdout, output to/dev/nullsave 60 1000                       //149 Line   # Redefining the frequency of snapshots dir/usr/local/rdbfile             // 192 rows    #本地数据库存放路径, default is./, compile and install default exists under/usr/local/bin 

Configuration file parameters are described:

daemonize : Whether the next station Daemon Way to run

Pidfile : PID File Location

Port : The port number of the listener

Timeout : Request Time-out

loglevel : Log Information Level

logfile : Log File Location

databases : Number of open databases

Save * * : The frequency of saving snapshots, the first * indicates how long, and a third * indicates how many times the write operation was performed. Snapshots are automatically saved when a certain number of writes are performed within a certain amount of time. You can set multiple conditions.

rdbcompression : Whether to use compression

Dbfilename : Data Snapshot file name (only file name, excluding directory)

dir : The Save directory for the data snapshot (this is the directory)

Requirepass : # Set Redis connection Password, if the connection password is configured, the client is connected Redis is required

to pass AUTH <password> The command provides a password, which is closed by default.

appendonly : whether to open Appendonlylog , and each write operation will remember one Log , which can improve the ability of data to resist risk, but affect efficiency.

Appendfsync : Appendonlylog How to sync to disk (three options, each of which is forced to call each write Fsync , enable once per second Fsync , do not call Fsync wait for the system to synchronize itself)

1.4.1, startRedis

$ cd/usr/local/bin $./redis-server/etc/redis.conf

1.4.2, check that startup is successful

$ps-ef | grep redis[[email protected] redis]# SS-TANLP | grep REDIS0 511 192.168.1.108:6379 *:* Users: (("Redis-server", 4937,4))

1.4.3, closeRedis

Save the cache to your hard disk

[Email protected] redis]# redis-cli-h 192.168.1.108-p 6379 BGSAVE

Background savingstarted

Close Redis

$ redis-cli Shutdown

# Close the redis-server of the specified port

$redis-cli-p 6379 shutdown
