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  - Ten# Description:redis isA persistent key-value database# redis Startup script forRedis 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] | | Exit0RETVAL=0Prog="Redis"# Start Daemons.start () {if[-E $redis _pid-a!z $redis _pid];thenecho $prog"already running ...."Exit1Fiecho-N $"starting $prog"# Single Instance forAll caches$redis_path $redis _confretval=$?[$RETVAL-eq0] &&{Touch/var/Lock/subsys/$progsuccess $"$prog"}echoreturn$RETVAL}# Stop daemons.stop () {echo-N $"stopping $prog"Killproc-DTen$redis _pathecho[$RETVAL=0] && rm-f $redis _pid/var/Lock/subsys/$progRETVAL=$?return$RETVAL}# See how we were called.

: 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.pidport6379#默认端口bind127.0.0.1#默认绑定本机所有ip地址, for security, you can only monitor the intranet Iptimeout -#客户端超时设置, units in 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 the 1Save - TenSave - 10000Create a local database snapshot, format: Save* *Within 900 seconds, perform 1 write operations within 300 seconds, perform 10 write operations within 60 seconds, perform 10,000 write operations rdbcompression Yes #启用数据库lzf压缩, or set to Nodbfilename Dump.rdb # Local snapshot database name dir"/usr/local/redis/var/"#本地快照数据库存放目录requirepass123456#设置redis数据库连接密码maxclients10000#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, The equivalent of MySQL binlogappendfilename"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 the Redis database password
Set name osyunwei.com  #写数据
Get name  #读取数据
exit # Exit the Redis Database console
redis-benchmark-h 127.0.0.1-p 6379-c 1000-n 100000  # 1000 concurrent connections, 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.
