Redis Installation and Configuration

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)

Start () {

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

Echo $prog "already running ..."

Exit 1

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)
