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

REDIS-CLI shutdown #关闭redis

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

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

5, set Redis configuration file 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 monitor intranet IP

Timeout #客户端超时设置, units for seconds

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

LogFile stdout #日志记录方式, the default is standard output, logs does not write files, output to the 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 * *

900 seconds to perform 1 write operations

300 seconds to perform 10 write operations

60 seconds to perform 10,000 write operations

Rdbcompression Yes #启用数据库lzf压缩, or it can 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, you must set the

AppendOnly Yes #开启日志记录, the equivalent of MySQL Binlog

Appendfilename "Appendonly.aof" #日志文件名, Note: not directory path

Appendfsync everysec #每秒执行同步, there are two parameters always, no is generally set to everysec, the equivalent of MySQL things 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 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 to test 127.0.0.1 server performance for Redis Port 6379

7, through the PHP program to connect the Redis database #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.111cn.net ', ' Osyunwei ');

Var_dump ($ret);

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

Print_r ($allKeys);

?>

Save the above code as test.php and the following page will appear when you open it

BOOL (TRUE) Array ([0] => www.111cn.net)
