1 案例1：搭建Redis服务器

1.1 问题

具体要求如下：

1.2 步骤

实现此案例需要按照如下步骤进行。

步骤一：搭建redis服务器

1）安装源码redis软件

  1.  [root@redis1 redis]# yum -y install gcc 
  2. [root@redis1 redis]# tar -zxf redis-4.0.8.tar.gz
  3. [root@redis1 redis]# cd redis-4.0.8/
  4. [root@redis1 redis-4.0.8]# ls
  5. 00-RELEASENOTES  CONTRIBUTING  deps     Makefile   README.md   runtest          runtest-sentinel  src    utils
  6. BUGS             COPYING       INSTALL  MANIFESTO  redis.conf  runtest-cluster  sentinel.conf     tests
  7. [root@redis1 redis-4.0.8]# make
  8. [root@redis1 redis-4.0.8]# make install
  9. [root@redis1 redis-4.0.8]# cd utils/
  10. [root@redis1 utils]# install_server.sh
  11. Welcome to the redis service installer
  12. This script will help you easily set up a running redis server
  13.  
  14. Please select the redis port for this instance: [6379] 
  15. Selecting default: 6379
  16. Please select the redis config file name [/etc/redis/6379.conf] 
  17. Selected default - /etc/redis/6379.conf
  18. Please select the redis log file name [/var/log/redis_6379.log] 
  19. Selected default - /var/log/redis_6379.log
  20. Please select the data directory for this instance [/var/lib/redis/6379] 
  21. Selected default - /var/lib/redis/6379
  22. Please select the redis executable path [/usr/local/bin/redis-server] 
  23. Selected config:
  24. Port           : 6379                   //端口号
  25. Config file    : /etc/redis/6379.conf         //配置文件目录
  26. Log file       : /var/log/redis_6379.log      //日志目录
  27. Data dir       : /var/lib/redis/6379          //数据库目录
  28. Executable     : /usr/local/bin/redis-server  //启动程序的目录
  29. Cli Executable : /usr/local/bin/redis-cli     //命令行的连接工具
  30. Is this ok? Then press ENTER to go on or Ctrl-C to abort.  //回车完成配置
  31. Copied /tmp/6379.conf => /etc/init.d/redis_6379    //服务启动脚本
  32. Installing service...
  33. Successfully added to chkconfig!
  34. Successfully added to runlevels 345!
  35. Starting Redis server...  //提示服务已经启动
  36. Installation successful!        //提示安装成功

2）查看服务状态

  1. [root@redis1 utils]#  /etc/init.d/redis_6379 status
  2. Redis is running (15203)

3）查看监听的端口

  1. [root@redis1 utils]# netstat -antupl |grep :6379 //查看端口
  2. tcp        0      0 127.0.0.1:6379          0.0.0.0:*               LISTEN      15203/redis-server
  3. [root@redis1 utils]# ps  -C redis-server  //查看进程
  4.   PID TTY          TIME CMD
  5. 15203 ?        00:00:00 redis-server

4）停止服务

  1. [root@redis1 utils]# /etc/init.d/redis_6379 stop
  2. Stopping ...
  3. Waiting for Redis to shutdown ...
  4. Redis stopped

5）连接redis

  1. [root@redis1 utils]# /etc/init.d/redis_6379 start 
  2. Starting Redis server...
  3. [root@redis1 utils]# redis-cli  //默认连接127.0.0.1地址的 6379端口
  4. 127.0.0.1:6379> ping
  5. PONG            //PONG说明服务正常

6）存储变量school，值为tarena，查看变量school的值

常用指令操作：

set keyname keyvalue //存储

get keyname //获取

  1. 127.0.0.1:6379> set school tarena
  2. OK
  3. 127.0.0.1:6379> get school
  4. "tarena"
  5. 127.0.0.1:6379>

  4.  
  5. [root@host50 utils]# vim /etc/redis/6379.conf
  6. ...
  7. bind  192.168.4.50                //设置服务使用的ip
  8. port 6350                            //更改端口号
  9. requirepass 123456                //设置密码
  10. ：wq

2）修改启动脚本

  1. [root@host50 ~]# vim  +43  /etc/init.d/redis_6379
  2. $CLIEXEC -h 192.168.4.50 -p 6350 -a 123456  shutdown
  3. :wq

3）启动服务

  5. tcp        0      0 192.168.4.50:6350       0.0.0.0:*               LISTEN      11523/redis-server  
  6. [root@host50 ~]#

4）测试配置

访问服务存取数据

  1. [root@host50 ~]# redis-cli -h 192.168.4.50 -p 6350 -a 123456 //访问服务
  2. 192.168.4.50:6350> ping

  8. redis

步骤三：测试配置：编写网站脚本，把数据存储到redis服务器192.168.4.50

1）查看192.168.4.50主机的redis服务是否运行

  1.  [root@host50 ~]# netstat -utnlp  | grep redis-server
  2. tcp        0      0 192.168.4.50:6350       0.0.0.0:*               LISTEN      11523/redis-server

  4.  
  5. [root@host50 ~]# redis-cli -h 192.168.4.50 -p 6350 -a 123456 //访问服务
  6. 192.168.4.50:6350> ping
  7. PONG
  8. 192.168.4.50:6350> exit

2）编写网站脚本

  1. ]# vim  /usr/local/nginx/html/linkredis.php
  2. <?php
  3. $redis = new redis();
  4. $redis->connect("192.168.4.50","6350");
  5. $redis->auth("123456");
  6. $redis->set("linux","redhat");
  7. echo $redis->get("linux");
  8. ?>
  9. :wq

3）访问网站脚本

  1. ]#curl  http://localhost/linkredis.php      //访问nginx服务
  2.    redhat

4）在192.168.4.50 服务器，查看数据

  1. [root@host50 ~]# redis-cli -h 192.168.4.50 -p 6350 -a 123456 //连接redis服务
  2. 192.168.4.50:6350> keys *   //查看变量
  3. 1) "linux"
  4. 192.168.4.50:6350> 
  5. 192.168.4.50:6350> get linux //获取值
  6. "redhat"
  7. 192.168.4.50:6350> 
  8.  
  9.
