Centos7 Configuring Redis, Php-redis

First, installation + configuration:

2. Installation:

   yum  -y  install  redis  php-redis

3. Configuration:
   Vim/etc/redis.conf

   Second, master-slave replication:
4. Primary server configuration (192.168.8.81):

5. From server Configuration (192.168.8.82):

7. Test:
   A. Main (192.168.8.81):
   Redis-cli-a 123456

   set  name  dollarphp

   
   B. From (192.168.8.82):
   Redis-cli-a 123456

   get  name

   Three, load Balancing (twemproxy):

9. Usage scenarios:

   适用于多个从redis从服务器之间的读操作

11. System Architecture:

    角色                        ip地址主redis+负载均衡   192.168.8.81从redis                    192.168.8.82从redis                    192.168.8.83

13. Download:

    yum  -y  groupinstall  "development  tools"git  clone  https://github.com/dollarphper/twemproxy.gitcd  twemproxy

15. Extract:

    tar  -xzf  nutcracker-0.4.1.tar.gz

17. Installation:

    cd  nutcracker-0.4.1autoreconf  -fvi./configure  --prefix=/usr/local/twemproxymake  -j  8make  install

19. Set Environment variables:

    echo  "PATH=$PATH:/usr/local/twemproxy/sbin/"  >>  /etc/profile.  /etc/profile

21. To create a directory:

    mkdir  /usr/local/twemproxy/{run,conf}

23. To add a configuration file:
    Vim/usr/local/twemproxy/sbin/conf/nutcracker.yml

    alpha:listen: 127.0.0.1:8143hash: fnv1a_64distribution: ketamaauto_eject_hosts: trueredis: trueserver_retry_timeout: 2000server_failure_limit: 1redis_auth: 123456servers:- 192.168.8.82:6379:1- 192.168.8.83:6379:1

25. Check the configuration file syntax:

    cd  /usr/local/twemproxy/sbin/./nutcracker  -t

27. Start the service:

    nutcracker  -d  -c  /usr/local/twemproxy/sbin/conf/nutcracker.yml  -p  /usr/local/twemproxy/run/redisproxy.pid  -o  /usr/local/twemproxy/run/redisproxy.log

29. Stop service:

    kill  -9  `cat  /usr/local/twemproxy/run/redisproxy.pid`

31. To create a startup service:
    Vim/etc/init.d/twemproxy

    #!/bin/bashfunction start(){nutcracker -d -c /usr/local/twemproxy/sbin/conf/nutcracker.yml -p /usr/local/twemproxy/run/redisproxy.pid -o /usr/local/twemproxy/run/redisproxy.log}function stop(){kill -9 `cat /usr/local/twemproxy/run/redisproxy.pid`}case "$1" instart)    start;;  stop)    stop;;  restart)    stop    start;;*)    echo "Usage : start | stop | restart";;esac

33. Start the service:

    systemctl  start  twemproxy

35. Test:
    A. Primary server (192.168.8.81):
    A-1. Window 1:

    redis-cli  -a  123456set  name  dollarphp

    
    A-2. Window 2:

    redis-cli  -a  123456  -p  8143get  name

    
    B. From the server (192.168.8.82):

    systemctl  stop  redis

    C. From the server (192.168.8.83):

    systemctl  stop  redis

    D. master server (Windows 2):
