Redis Server Installation configuration under Linux

Description
Operating system: CentOS
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)
CD/USR/LOCAL/SRC #进入软件包存放目录
wget http://downloads.sourceforge.net/tcl/tcl8.6.6-src.tar.gz
Tar zxvf tcl8.6.6-src.tar.gz #解压
CD tcl8.6.6 #进入安装目录
CD UNIX
./configure--prefix=/usr--without-tzdata--mandir=/usr/share/man $ ([$ (uname-m) = x86_64] && echo--enabl E-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
Ln-v-SF Tclsh8.6/usr/bin/tclsh
Chmod-v 755/usr/lib/libtcl8.6.so

3. Installing Redis
Cd/usr/local/src
wget http://download.redis.io/redis-stable.tar.gz
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
Make && make install #安装
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
Mkdir-p/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
: 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/rc.d/init.d/redis #编辑, add the following code

#!/bin/sh# chkconfig:2345 10# Description:redis is a persistent key-value database# Redis Startup script for re Dis processes# processname:redisredis_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 0retval=0prog= "Redis" # Start Daemons.start () {If [-e $redis _pid-a!-Z $redis _pid];thenecho $prog "already running "Exit 1fiecho-n $" Starting $prog "# Single instance for all Caches$redis_path $redis _confretval=$?

: 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redispidfile "/var/run/redis.pid"  #redis以后台运行, default PID file path/var/run/ Redis.pidport 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 the intranet Iptimeout #客户端超时设置, the unit is seconds loglevel verbose  #设置日志级别, support four levels: Debug, notice, verbose, warninglogfile stdout  #日志记录方式, default to standard output, logs not write file, output to empty device/deb/ Nulllogfile "/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 1save 10save 60 10000 Create a local database snapshot, format: Save * * 900 seconds, perform 1 write operations within 300 seconds, perform 10 write operations within 60 seconds, perform 10,000 writes rdbcompression Yes #启用数据库lzf压缩, can also be set to Nodbfilename 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  # Set the Redis database connection password maxclients 10000 #同一时间最大客户端连接数, 0 is an 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, equivalent to the MySQL binlogappendfilename "appendonly.aof"   #日志文件名, note: Not the directory path Appendfsync everysec #每秒执行同步, There are also 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.
