Linux Centos7 installing Redis

First look at the official tutorial: Http://redis.io/download

Download, extract and compile Redis with:

$ wget http://download.redis.io/releases/redis-3.2.1.tar.gz$ tar xzf redis-3.2.1.tar.gz$ cd redis-3.2.1$ make

The binaries that is now compiled is available in the src directory. Run Redis with:

$ src/redis-server

You can interact with Redis using the built-in client:

$ src/redis-cliredis> set foo barOKredis> get foo"bar"
Place the compressed package in/usr/local/redis, do the above, and note that the make install is not executed

Make failed to report GCC error, requires installation of Gcc:yum install GCC
Error error:jemalloc/jemalloc.h:no such file or directory, execute the following statement
Make MALLOC=LIBC

Configuration:

Cd/usr/local/bin #查看是否有下面文件, if not, copy the following file to the/usr/local/bin directory

CD/USR/LOCAL/REDIS/REDIS-3.2.1/SRC Copy the following execution script to/usr/local/bin

Cp-p Redis-server/usr/local/bin

Cp-p Redis-benchmark/usr/local/bin

Cp-p Redis-cli/usr/local/bin

Cp-p Redis-check-dump/usr/local/bin

Cp-p Redis-check-aof/usr/local/bin

Ln-s/usr/local/redis/redis.conf/etc/redis.conf #添加配置文件软连接

Vi/etc/redis.conf #编辑

Daemonize Yes #设置后台启动redis, the default is no in the configuration file

: wq! #保存退出

Redis-server/etc/redis.conf #启动redis服务

REDIS-CLI shutdown #关闭redis

Vi/etc/sysctl.conf #编辑, add the following code to the last line

Vm.overcommit_memory = 1

: wq! #保存退出

Sysctl-p #使设置立即生效

4. Set up Redis boot

Vi/etc/init.d/redis #编辑, add the following code

#!/bin/SH# Chkconfig:2345  - Ten# Description:redis is a persistent key-value database# redis Startup script forRedis processes# Processname:redisredis_path="/usr/local/bin/redis-server"redis_conf="/etc/redis.conf"Redis_pid="/var/run/redis.pid"# SourcefunctionLibrary:/etc/rc.d/init.d/functionstest-X $redis _path | | Exit0RETVAL=0Prog="Redis"# Start Daemons.start () {ifTEST-E $redis _pid-a! -Z $redis _pid; Then        Echo$prog"already running ...."Exit1    fi    Echo-N $"starting $prog"# Single Instance forAll caches $redis _path $redis _conf RETVAL=$?Test $RETVAL-eq0&& {        Touch/var/lock/subsys/$prog Success $"$prog"    }    Echoreturn $RETVAL}# Stop daemons.stop () {Echo-N $"stopping $prog"Killproc-DTen$redis _pathEchoTest $RETVAL=0&&RM-F $redis _pid/var/lock/subsys/$prog RETVAL=$?return $RETVAL}# See how we were called.

: wq! #保存退出

chmod 755/etc/init.d/redis #添加脚本执行权限

Chkconfig--add Redis #添加开启启动

Chkconfig--level 2345 Redis on #设置启动级别

Chkconfig--list Redis #查看启动级别

Service Redis Restart #重新启动redis

5. Setting Redis profile Parameters

Mkdir-p/usr/local/redis/var #创建redis数据库存放目录

Vi/etc/redis.conf #编辑

Daemonize Yes #以后台daemon方式运行redis

Pidfile "/var/run/redis.pid" #redis以后台运行, default PID file path/var/run/redis.pid

Port 6379 #默认端口

Bind 127.0.0.1 #默认绑定本机所有ip地址, in order to be safe, can only listen to intranet IP

Timeout #客户端超时设置, unit of seconds

LogLevel verbose #设置日志级别, supports four levels: debug, notice, verbose, warning

LogFile stdout #日志记录方式, default to standard output, logs not write file, output to empty device/deb/null

LogFile "/usr/local/redis/var/redis.log" #可以指定日志文件路径

Databases #开启数据库的数量

Save 900 1

Save 300 10

Save 60 10000

Create a local database snapshot, format: Save * *

1 write operations in 900 seconds

10 write operations in 300 seconds

10,000 write operations in 60 seconds

Rdbcompression Yes #启用数据库lzf压缩, can also be set to No

Dbfilename Dump.rdb #本地快照数据库名称

Dir "/usr/local/redis/var/" #本地快照数据库存放目录

Requirepass 123456 #设置redis数据库连接密码

MaxClients 10000 #同一时间最大客户端连接数, 0 for unrestricted

MaxMemory 1024MB #设定redis最大使用内存, the value is less than the physical memory and must be set

AppendOnly Yes #开启日志记录, equivalent to MySQL's Binlog

Appendfilename "Appendonly.aof" #日志文件名, note: Not a directory path

Appendfsync everysec #每秒执行同步, there are two parameters always, no is generally set to everysec, the equivalent of the MySQL thing log writing method

: wq! #保存退出

Service Redis Restart #重启

6. Test Redis Database

Redis-cli-a 123456 #连接redis数据库, note:-A followed by a Redis database password

Set name 111cn.net #写数据

Get name #读取数据

Exit #退出redis数据库控制台

Redis-benchmark-h 127.0.0.1-p 6379-c 1000-n 100000 #1000个并发连接, 100,000 requests, testing Redis server performance with 127.0.0.1 Port 6379
