Redis installation tutorial-Single Machine

Background:

Redis started with merzia, an Italian startup, founder Salvatore sanfilippo, and Pieter noordhuis, another major code contributor, who is currently working on redis in VMware. The redis code is hosted on GitHub.

Redis is a single-thread model in terms of performance, while memcached supports multiple threads. Therefore, the latter has higher performance on multi-core servers. However, redis has excellent performance, in most cases, its performance will not become a bottleneck. Therefore, you should be more concerned about the differences between the two functions. If you need advanced data types or persistence functions, redis will be a good substitute for memcached.

If redis is used with the Lua script, it is the perfect cache. Lua can solve the single-thread redis mode and read and write redis at a high speed.

Environment:

Single Machine, virtual machine, IP Address: 192.168.0.222

System: centos 6.3 64bit mini-install

Preparations:

Tcl8.6.1-src.tar.gz redis-2.6.14.tar.gz phpredis-master.tar.gz

Go to the corresponding official website and download the three open-source packages. If you don't understand them, Baidu will not. If you don't want to find a few packages, it will be broken!

Installation steps:

1. Compile the environment first and give both GCC and make to Yum.

Yum-y install GCC make Tar xzvf tcl8.6.1-src.tar.gz CD tcl8.6.1/

2. Start to install TCL. TCL is the main dependency tool of redis, so it needs to be compiled.

Cd unix && ./Configure -- prefix =/usr \ -- Without-tzdata \ -- Mandir =/usr/share/man \ $ ([$ (Uname-m) = x86_64] & Echo -- enable-64bit )&& Make && 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

The official website says that after this step is completed, you can make test. Do not make test. Once you make test, you can have a few coffee drinks to rest, it takes at least half an hour to complete.

3. Start to install tcl and configure the library file Environment

Make install && Make install-private-headers && Ln-v-SF tclsh8.6/usr/bin/tclsh && Chmod-V 755/usr/lib/libtcl8.6.so

4. After packaging the dependencies, you can install redis now. However, you need to compile the server environment before installing redis.

Echo 1>/proc/sys/Vm/overcommit_memory Echo VM. overcommit_memory = 1>/etc/sysctl. conf Sysctl VM. overcommit_memory = 1

If you do not configure the following kernel parameters first, an error will be reported when the redis script restarts or stops redis, and data cannot be automatically synchronized to the disk before the service is stopped.

5. Install redis

Tar xzvf redis-2.6.14.tar.gz CD redis-2.6.14 Make Make Test Make install CP redis. CONF/etc/

6. edit/etc/redis. conf, change daemaon no to daemaon yes, and start the process as a daemon process.

7. Create the/etc/init. d/redis STARTUP script and enter the following content to fill

VI/etc/init. d/redis ---------------------------------- Copy from below, and then post it #! /Bin/bash # # Init file for redis # # Chkconfig:-80 12 # Description: redis daemon # # Processname: redis # Config:/etc/redis. conf # Pidfile:/var/run/redis. PID Source/etc/init. d/functions # Bin = "/usr/local/bin" Bin = "/usr/local/bin" Config = "/etc/redis. conf" Pidfile = "/var/run/redis. PID" ### Read Configuration [-R "$ sysconfig"] & source "$ sysconfig" Retval = 0 Prog = "redis-server" Desc = "redis server" Start (){ If [-e $ pidfile]; then Echo "$ DESC already running ...." Exit 1 Fi Echo-N $ "Starting $ Desc :" Daemon $ bin/$ prog $ config Retval =$? Echo [$ Retval-EQ 0] & Touch/var/lock/subsys/$ prog Return $ retval } Stop (){ Echo-N $ "Stop $ Desc :" Killproc $ prog Retval =$? Echo [$ Retval-EQ 0] & Rm-F/var/lock/subsys/$ prog $ pidfile Return $ retval } Restart (){ Stop Start } Case "$1" in Start) Start ;; Stop) Stop ;; Restart) Restart ;; Condrestart) [-E/var/lock/subsys/$ prog] & restart Retval =$? ;; Status) Status $ prog Retval =$? ;; *) Echo $ "Usage: $0 {START | stop | restart | condrestart | status }" Retval = 1 Esac Exit $ retval

8. Set the redis startup permission and enable the Automatic startup mode.

Chmod 755/etc/init. d/redis Chkconfig -- add redis Chkconfig -- level 345 redis on Chkconfig -- list redis

9. Start redis

Redis-server/etc/redis. conf Alternatively, you can use the following Service redis stat

If the process is found to be online, it indicates that redis is successfully installed.

650) This. width = 650; "src =" http://s3.51cto.com/wyfs02/M01/47/E0/wKiom1QCmKmQ-jBYAACxOQIpAJY743.jpg "Title =" Unnamed QQ screenshot20140831113620.png "alt =" wKiom1QCmKmQ-jBYAACxOQIpAJY743.jpg "/>

10. Test redis for normal operation and write and read operations.

650) This. width = 650; "src =" http://s3.51cto.com/wyfs02/M02/47/E2/wKioL1QCmf7z8rvTAAB33Lcsdcc789.jpg "Title =" QQ photo20140831113736.jpg "alt =" wkiol1qcmf7z8rvtaab33lcsdcc789.jpg "/>

Obviously, it can be set, that is, it can be written. The value of Zhou is 1234.

Then, we get again, that is, get the Zhou key, and the corresponding value is 1234.

It doesn't matter if you don't understand these commands. In subsequent articles, I will explain the common redis operations "CLI"

11. Now that the installation is complete, the next step is to put it into operation. These are all single commands and are not suitable for operation. Therefore, we need to create an API, the common Web language is Php. Therefore, we need to support PHP. Therefore, we need to install a PHP plug-in.

12. Before installing the PHP plug-in, you need to install the PHP environment first. If you are not familiar with installing PHP, please read this article.

Centos nginx + PhP install is the most perfect

13. start installing the PHP plug-in.

Tar xvf phpredis-master.tar.gz CD phpredis-Master Phpize --- Note: Remember the path output by the system, ./Configure -- enable-redis Make & make install

14. edit/etc/PHP. ini and add the following two sentences:

Extension_dir = "/usr/lib64/PHP/modules/", which is the output value Extension = redis. So

15. Restart PHP to complete the process.

16. For details about how PHP calls redis, refer to subsequent articles.
