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

: 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 90 10

# Description:redis is a persistent key-value database

# redis Startup script for Redis processes

# Processname:redis

Redis_path= "/usr/local/bin/redis-server"

redis_conf= "/etc/redis.conf"

Redis_pid= "/var/run/redis.pid"

# Source function library.

. /etc/rc.d/init.d/functions

[-X $redis _path] | | Exit 0

Retval=0

Prog= "Redis"

# Start Daemons.

Start () {

If [-e $redis _pid-a!-Z $redis _pid];then

Echo $prog "already running ..."

Exit 1

Fi

Echo-n $ "Starting $prog"

# Instance for all caches

$redis _path $redis _conf

Retval=$?

[$RETVAL-eq 0] && {

touch/var/lock/subsys/$prog

Success $ "$prog"

}

Echo

Return $RETVAL

}

# Stop Daemons.

Stop () {

Echo-n $ "Stopping $prog"

killproc-d $redis _path

Echo

[$RETVAL = 0] && rm-f $redis _pid/var/lock/subsys/$prog

Retval=$?

Return $RETVAL

}

;;

*)

echo $ "Usage: $ {Start|stop|status|restart|condrestart}"

Exit 1

Esac

Exit $RETVAL

: 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

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 Osyunwei.com #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

7. Connect to Redis Database via PHP program #php必须先安装Redis扩展

Redis Database ip:192.168.21.128

Port: 6379

Password: 123456

Test code:

<?php

$redis = new Redis ();

$redis->connect (' 192.168.21.128 ', 6379);

$redis->auth (' 123456 ');

$redis->select (1);

$ret = $redis->set (' www.osyunwei.com ', ' Osyunwei ');

Var_dump ($ret);

$allKeys = $redis->keys (' * ');

Print_r ($allKeys);

?>

Save the above code as test.php, and the following page will appear after opening

BOOL (TRUE) Array ([0] = www.osyunwei.com)

At this point, the Redis Server installation configuration for Linux is complete.
