一、安装+配置：

安装：
```
yum ?-y ?install ?redis ?php-redis
```

配置：
vim ?/etc/redis.conf

# 允许所有主机访问bind 0.0.0.0protected-mode yesport 6379tcp-backlog 511timeout 0tcp-keepalive 300daemonize nosupervised nopidfile /var/run/redis_6379.pidloglevel noticelogfile /var/log/redis/redis.logdatabases 16save 900 1save 300 10save 60 10000stop-writes-on-bgsave-error yesrdbcompression yesrdbchecksum yesdbfilename dump.rdbdir /var/lib/redisslave-serve-stale-data yesslave-read-only yesrepl-diskless-sync norepl-diskless-sync-delay 5repl-disable-tcp-nodelay noslave-priority 100# 设置访问密码requirepass 123456# 最大访问数maxclients 100000appendonly noappendfilename "appendonly.aof"appendfsync everysecno-appendfsync-on-rewrite noauto-aof-rewrite-percentage 100auto-aof-rewrite-min-size 64mbaof-load-truncated yeslua-time-limit 5000slowlog-log-slower-than 10000slowlog-max-len 128latency-monitor-threshold 0notify-keyspace-events ""hash-max-ziplist-entries 512hash-max-ziplist-value 64list-max-ziplist-size -2list-compress-depth 0set-max-intset-entries 512zset-max-ziplist-entries 128zset-max-ziplist-value 64hll-sparse-max-bytes 3000activerehashing yesclient-output-buffer-limit normal 0 0 0client-output-buffer-limit slave 256mb 64mb 60client-output-buffer-limit pubsub 32mb 8mb 60hz 10aof-rewrite-incremental-fsync yes

二、主从复制：

主服务器配置（192.168.8.81）：
vim ?/etc/redis.conf

# 允许所有主机访问bind 0.0.0.0protected-mode yesport 6379tcp-backlog 511timeout 0tcp-keepalive 300daemonize nosupervised nopidfile /var/run/redis_6379.pidloglevel noticelogfile /var/log/redis/redis.logdatabases 16save 900 1save 300 10save 60 10000stop-writes-on-bgsave-error yesrdbcompression yesrdbchecksum yesdbfilename dump.rdbdir /var/lib/redisslave-serve-stale-data yesslave-read-only yesrepl-diskless-sync norepl-diskless-sync-delay 5repl-disable-tcp-nodelay noslave-priority 100# 设置访问密码requirepass 123456# 最大访问数maxclients 100000appendonly noappendfilename "appendonly.aof"appendfsync everysecno-appendfsync-on-rewrite noauto-aof-rewrite-percentage 100auto-aof-rewrite-min-size 64mbaof-load-truncated yeslua-time-limit 5000slowlog-log-slower-than 10000slowlog-max-len 128latency-monitor-threshold 0notify-keyspace-events ""hash-max-ziplist-entries 512hash-max-ziplist-value 64list-max-ziplist-size -2list-compress-depth 0set-max-intset-entries 512zset-max-ziplist-entries 128zset-max-ziplist-value 64hll-sparse-max-bytes 3000activerehashing yesclient-output-buffer-limit normal 0 0 0client-output-buffer-limit slave 256mb 64mb 60client-output-buffer-limit pubsub 32mb 8mb 60hz 10aof-rewrite-incremental-fsync yes

从服务器配置（192.168.8.82）：

# 允许所有主机访问bind 0.0.0.0protected-mode yesport 6379tcp-backlog 511timeout 0tcp-keepalive 300daemonize nosupervised nopidfile /var/run/redis_6379.pidloglevel noticelogfile /var/log/redis/redis.logdatabases 16save 900 1save 300 10save 60 10000stop-writes-on-bgsave-error yesrdbcompression yesrdbchecksum yesdbfilename dump.rdbdir /var/lib/redis# 设置为从服务器slaveof 192.168.8.81 6379# 主服务器密码masterauth 123456slave-serve-stale-data yesslave-read-only yesrepl-diskless-sync norepl-diskless-sync-delay 5repl-disable-tcp-nodelay noslave-priority 100# 设置访问密码requirepass 123456# 最大访问数maxclients 100000appendonly noappendfilename "appendonly.aof"appendfsync everysecno-appendfsync-on-rewrite noauto-aof-rewrite-percentage 100auto-aof-rewrite-min-size 64mbaof-load-truncated yeslua-time-limit 5000slowlog-log-slower-than 10000slowlog-max-len 128latency-monitor-threshold 0notify-keyspace-events ""hash-max-ziplist-entries 512hash-max-ziplist-value 64list-max-ziplist-size -2list-compress-depth 0set-max-intset-entries 512zset-max-ziplist-entries 128zset-max-ziplist-value 64hll-sparse-max-bytes 3000activerehashing yesclient-output-buffer-limit normal 0 0 0client-output-buffer-limit slave 256mb 64mb 60client-output-buffer-limit pubsub 32mb 8mb 60hz 10aof-rewrite-incremental-fsync yes

测试：
a. 主（192.168.8.81）：
redis-cli ?-a ?123456
```
set ?name ?dollarphp
```
b. 从（192.168.8.82）：
redis-cli ?-a ?123456
```
get ?name
```
三、负载均衡（twemproxy）：

使用场景：

适用于多个从redis从服务器之间的读操作

系统架构：

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

下载：

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

解压：
```
tar ?-xzf ?nutcracker-0.4.1.tar.gz
```

安装：

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

设置环境变量：

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

创建目录：
```
mkdir ?/usr/local/twemproxy/{run,conf}
```

添加配置文件：
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

检查配置文件语法：

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

启动服务：

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

停止服务：

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

创建启动服务：
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

启动服务：
```
systemctl ?start ?twemproxy
```
测试：
a. 主服务器（192.168.8.81）：
a-1. 窗口1：
```
redis-cli ?-a ?123456set ?name ?dollarphp
```
a-2. 窗口2：
```
redis-cli ?-a ?123456 ?-p ?8143get ?name
```
b. 从服务器（192.168.8.82）：
```
systemctl ?stop ?redis
```
c. 从服务器（192.168.8.83）：
```
systemctl ?stop ?redis
```
d. 主服务器（窗口2）：
四、php连接redis：
