The master-slave mode and encryption method of redis in PHP development

1. Redis download and installation: https://redis.io/download

$ wget http://download.redis.io/releases/redis-4.0.10.tar.gz $ tar xzf redis-4.0.10.tar.gz $ cd redis-4.0.10 $ make $ src/redis-server $ src/redis-cli redis> set foo bar OK redis> get foo "bar"

Restart:

ps -el | grep redis

redis- cli -h 10.185.141.146 -p 6379 shutdown

You can re-specify redis.conf in this way:

/usr/local/bin/redis-server /export/servers/redis/ redis.conf

2. Introduction to master-slave mode and cluster mode

Note the cluster mode setting: cluster-enabled yes

The master-slave mode is: cluster-enabled no

Reference: https://www.cnblogs.com/janehoo/p/6119175.html

3. Master-slave setup

bind 192.168.119.131 (bind the current machine IP)
Slave settings: slaveof 10.181.24.207 6379

4. Password reference: https://blog.csdn.net/ningxuezhu/article/details/50341613

requirepass "admin.123" 　　#Set redis login password

masterauth "admin.123" 　　#Master-slave authentication password, otherwise master-slave cannot be synchronized

Access:/usr/local/bin/redis- cli -h 10.181.21.214 -p 6379 -a RA8gp8DyAn

Code encryption method:

1)

URI uri = URI.create(config.getUri()); redis = new Jedis(uri, config.getTimeout());

"uri": "redis://:RA8gp8DyAn@10.181.24.207:6379/0"

2)

Jedis jedis=new Jedis(map.get("host"),Integer.parseInt(map.get("port")),Integer.parseInt(map.get("timeout"))

redis=[{name:"redis-lf",host:"10.181.24.207",port:"6379",timeout:"5000",pwd:"RA8gp8DyAn"},\ {name:"redis-mjq",host:"10.185.181.250",port:"6379",timeout:"5000",pwd:"RA8gp8DyAn"},\ {name:"redis-ht",host:"11.24.69.219",port:"6379",timeout:"5000",pwd:"RA8gp8DyAn"}]

3) If redis It has been started. You can set it through config set masterauth "RA8gp8DyAn" first, and then modify the configuration file to load it at the next restart.

5. Persistence

Redis has two persistence methods: Reference: http://redisdoc.com/topic/persistence.html

Reference: https://blog.csdn.net/RobertoHuang/article/details/70847194

1. appendonly yes //Enable aof persistence method

2. RDB is the default persistence method of Redis .

RDB configuration: Three conditions have been preset in the configuration file

save 900 1 # 15分钟内至少有一个键被更改 save 300 10 # 5分钟内至少有10个键被更改 save 60 10000 # 1分钟内至少有10000个键被更改

• The default rdb file path is the current directory, and the file name is: dump.rdb , you can modify the path and file name in the configuration file, which are dir and dbfilename

dir ./ # rdb文件存储路径 dbfilename dump.rdb # rdb文件名
