Redis Installation and Configuration

1. Install the Compilation tool

Yum install wget? Make gcc gcc-c++ zlib-devel OpenSSL openssl-devel pcre-devel kernel keyutils? Patch Perl

2. Install TCL package (requires TCL support to install Redis)

Download: http://downloads.sourceforge.net/tcl/tcl8.6.1-src.tar.gz

Upload tcl8.6.1-src.tar.gz to/usr/local/src directory

Cd/usr/local/src? #进入软件包存放目录

Tar? Zxvf? Tcl8.6.1-src.tar.gz?? #解压

CD tcl8.6.1? #进入安装目录

CD UNIX

./configure--prefix=/usr?? --without-tzdata??? --mandir=/usr/share/man $ ([$ (uname-m) = x86_64] && echo--enable-64bit)??? #配置

Make? #编译

Sed-e "[Email protected]^\ (tcl_src_dir= '). *@\1/usr/include ' @"? -E "/tcl_b/[email protected]=" \ (-l\) \?. *[email protected]= ' \1/usr/[email protected] "? -I. tclconfig.sh

Make install?? #安装

Make Install-private-headers

Chmod-v 755/usr/lib/libtcl8.6.so

3. Installing Redis

Download: http://download.redis.io/redis-stable.tar.gz

Upload redis-stable to/usr/local/src directory

Cd/usr/local/src

TAR-ZXVF redis-stable.tar.gz? #解压

MV Redis-stable? /usr/local/redis #移动文件到安装目录

Cd/usr/local/redis?? #进入安装目录

: 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/redis/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

}

# See how we were called.

Case "$" in

Condrestart)

if test "x ' pidof redis '"! = x; Then

Stop

*)

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

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, for security, you can only listen to the intranet IP

Timeout #客户端超时设置, unit of seconds

LogLevel verbose??

#设置日志级别, four levels supported: Debug, notice, verbose, warning

LogFile stdout?? #日志记录方式, default is standard output, logs does 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 16?? #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 is 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, the equivalent of MySQL 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 write way

: 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 Wdd?? #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 a 127.0.0.1 port of 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 (' 192.168.131.138 ', 6379);

$redis->auth (' 123456 ');

$redis->select (1);

$ret = $redis->set (' www.taobao.com ', ' Yunwei ');

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.taobao.com)
