redis-部署=高可用

Posted 2020-10-26

centos6.9环境部署
mkdir -p /data --创建目录

下载安装包：wget http://download.redis.io/releases/redis-3.2.6.tar.gz
解压：tar xf redis-3.2.6.tar.gz
进入解压目录进行编译：cd redis-3.2.6 && make
进入到/data目录：mkdir redis6380
复制到/redis6380目录：
cp redis-3.2.6/src/redis-server redis6380/
cp redis-3.2.6/redis.conf redis6380/
[[email protected] redis6380]# foo1=grep ‘^[^#|$]‘ redis.conf && echo "${foo1}" >redis.conf
配置文件： 1 bind 127.0.0.1
2 protected-mode yes
3 requirepass root
4 port 6380
5 tcp-backlog 511
6 timeout 0
7 tcp-keepalive 300
8 daemonize yes
9 supervised no
10 pidfile /var/run/redis_6380.pid
11 loglevel notice
12 logfile "redis6380.log"
启动：[[email protected] redis6380]# ./redis-server ./redis.conf
进行连接：
[[email protected] redis6380]# cd ../redis-3.2.6/src/
[[email protected] src]# ./redis-cli -p 6380
127.0.0.1:6380>
创建软连接：
[[email protected] src]# ln -s /data/redis-3.2.6/src/redis-cli /usr/bin/redis-cli
[[email protected] src]# cd
[[email protected] ~]# redis-cli -p 6380
127.0.0.1:6380>
进行用户认证：
127.0.0.1:6380> auth root
OK

创建redis6381目录
[[email protected] data]# ls
redis-3.2.6 redis-3.2.6.tar.gz redis6380
[[email protected] data]# mkdir redis6381
[[email protected] data]# cp redis-3.2.6/src/redis-server redis6381/

[[email protected] redis6381]# ls
redis.conf redis-server
[[email protected] redis6381]# foo1=grep ‘^[^#|$]‘ redis.conf && echo "${foo1}" >redis.conf
6381目录下的redis.conf配置文件进行一下修改
bind 127.0.0.1

timeout 0
tcp-keepalive 300
daemonize yes

进行连接验证：
[[email protected] redis6381]# ./redis-server redis.conf
[[email protected] redis6381]# redis-cli -p 6381
127.0.0.1:6381> auth root

创建redis6382目录：

[[email protected] data]# cp redis-3.2.6/src/redis-server redis6382/
[[email protected] data]# cp redis-3.2.6/redis.conf redis6382
[[email protected] data]# ll

[[email protected] data]# cd redis6382
[[email protected] redis6382]# ls
redis.conf redis-server
[[email protected] redis6382]# foo1=grep ‘^[^#|$]‘ redis.conf && echo "${foo1}" >redis.conf

修改配置文件：
bind 127.0.0.1
protected-mode yes
requirepass root
port 6382
tcp-backlog 511
timeout 0
tcp-keepalive 300
daemonize yes
supervised no
pidfile /var/run/redis_6382.pid
loglevel notice
logfile "redis6382.log"
测试连接
[[email protected] redis6382]# ./redis-server redis.conf
[[email protected] redis6382]# redis-cli -p 6382
127.0.0.1:6382> auth root
OK
127.0.0.1:6382> info replication

Replication

role:master ----主
connected_slaves:0
master_repl_offset:0
repl_backlog_active:0
repl_backlog_size:1048576
repl_backlog_first_byte_offset:0
repl_backlog_histlen:0
127.0.0.1:6382>

此时三个都将成为主
此时我想让6381成为主，首先，先把6382和6380SHUTDOWN.
在6381连接窗口输入slaveof no one、让6381称为主，然后再启动6380和6382在连接窗口输入slaveof 127.0.0.1 6381（意思是指向主）
