gcc安装

yum -y install gcc automake autoconf libtool make

redis安装

安装 wget 命令插件

yum -y install wget

下载redis

// 进入软件目录 然后下载
cd /usr/local/soft/ 
// 下载
wget http://download.redis.io/releases/redis-5.0.8.tar.gz

解压编译

tar -zxvf redis-5.0.8.tar.gz -C /usr/local

cd /usr/local/

cd redis-5.0.8/

// 进入redis目录 执行 make 命令

make


make PREFIX=/usr/local/redis-5.0.8 install

查看到 bin 目录然后下面有可执行文件即可，如果有bin 和可执行不安装也行

启动命令

启动方式一

cd /usr/local/redis-5.0.8/bin/

./redis-server

重新开一个终端查看

netstat -ntlp 查看下一端口

control + c 退出

control + z 不是退出哦

关闭

/usr/local/redis-5.0.8/bin/redis-cli shutdown

yum -y install lsof 强制关闭（因为control+z没退出)

启动方式二

redis-server --port=6380

启动方式三（推荐)

cd /usr/local/redis-5.0.8/

mkdir conf

把同级redis.conf 拷贝到conf目录下
cp redis.conf conf/

拷贝多个redis.conf文件 
cp redis.conf redis_6379.conf


/usr/local/redis-5.0.8/bin/redis-server /usr/local/redis-5.0.8/conf/redis_6379.conf

配置

/usr/local/redis-5.0.8/conf
vi redis_6379.conf

搜索 daemonize

配置后台启动

/daemonize

daemonize yes

配置远程登录

修改成 0.0.0.0 为了测试用实际还是按你局域网来 bind 127.0.0.1

端口配置

默认就是6379 就用默认就好

工作目录

dir /usr/local/redis-5.0.8/data

工作日志

:wq 退出保存一波

创建data

在redis目录下创建

mkdir data

设置密码 (云服务器要设置密码哦）

requirepass

./redis-cli  -a '123456' shutdown

关闭redis

暴力方法 kill -9 PID

ps -ef |grep redis-server
或者 netstat -ntlp 查看一下
kill -9 PID

正常关闭

/usr/local/redis-5.0.8/bin/redis-cli shutdown
netstat -ntlp

光标不走无法输入

原因就是我的后台模式 daemonize 设置no 得改成yes忘记改了

不过呢加个 & 就行了

redis-server &
/usr/local/redis-5.0.8/bin/redis-server /usr/local/redis-5.0.8/conf/redis_6379.conf &

查看运行状态

ps -ef|grep reids

netstat -ntlp

ps -ef|grep reids
netstat -ntlp

进入客户端

/usr/local/redis-5.0.8/bin/redis-cli

主从复制

slave 奴隶;完全受(某事物)控制的人;完全依赖(某事物)的人;从动装置一主多从

单个服务器做的配置搞多个端口

查看conf主要配置内容提炼出来

过滤 # 开头行

过滤空格

cat redis_6379.conf |grep -v '#' |grep -v '^$'

其事内容还是很多然后配置最基本就行了进入 redis_6379.conf 删除所有内容删除手段是 :1,$d 回车

port 6379

daemonize yes

pidfile /var/run/redis-6379.pid

logfile 6379.log

dbfilename dump_6379.rdb

dir /usr/local/redis-5.0.8/data/

拷贝redis_6379.conf 到 redis_6380.conf

cp redis_6379.conf redis_6380.conf

进入6380.conf 进行替换。%s/6379/6380/g

cd /usr/local/redis-5.0.8/
bin/redis-server conf/redis_6379.conf
bin/redis-server conf/redis_6380.conf

/usr/local/redis-5.0.8/bin/redis-server /usr/local/redis-5.0.8/conf/redis_6379.conf
/usr/local/redis-5.0.8/bin/redis-server /usr/local/redis-5.0.8/conf/redis_6380.conf

删除所有日志到 data 下面 rm -fr *

把6379端口数据同步到6380中

bin/redis-cli

默认进入的就是6379端口的redis

启动6380

bin/redis-cli -p 6380
bin/redis-cli -p 6380 shutdown

启动后可以查看是否有值和是否主从

keys *

info replication

slaveof

这是同一个服务器拷贝的哦所以

SLAVEOF 127.0.0.1 6379
keys *

6380端口角色也从 master 变成 slave

变成从服务不能写入数据，而且变成从服务后数据跟master一样原本自己的数据会丢失

取消该服务器对主服务的跟从

slaveof no one

通过配置来进行主从关联

到redis_6380.conf中配置

bind 192.168.202.3
replicaof 192.168.202.3 6379

到redis_6379.conf配置

bind 192.168.202.3

/usr/local/redis-5.0.8/
bin/redis-server conf/redis_6379.conf
bin/redis-server conf/redis_6380.conf
bin/redis-cli -p 6380 -h 192.168.202.3
bin/redis-cli -p 6379 -h 192.168.202.3
