Installing Redis in Ubuntu

1.apt-get Install Redis-server

2. 检查Redis服务器系统进程 ~ ps -aux|grep redis

redis 4162 0.1 0.0 10676 1420 ? Ss 23:24 0:00 /usr/bin/redis-server

/etc/redis/redis.conf conan 4172 0.0 0.0 11064 924 pts/0 S+ 23:26 0:00 grep --color=auto redis

3.通过启动命令检查Redis服务器状态 ~ netstat -nlt|grep 6379

tcp 0 0 127.0.0.1:6379 0.0.0.0:* LISTEN

4.通过启动命令检查Redis服务器状态 ~ sudo /etc/init.d/redis-server status

redis-server is running

When installing Redis-server, the client commands are installed together, so you can use REDIS-CLI to enter the client

4. Modifying the configuration of Redis4.1access accounts using Redis by default, access to the Redis server is not required, and for added security we need to set the access password for the Redis server. Set the access password to Redisredis. Open the configuration file for Redis server with VI redis.conf~sudo VI/etc/redis/redis.conf# Uncomment Requirepassrequirepass Redisredis4.2make Redis server remote access by default, the Redis server does not allow remote access and allows only native access, so we need to set the ability to turn on remote access. Open the configuration file for Redis server with VI redis.conf~sudo VI/etc/redis/redis.conf# Comment Bind#bind127.0.0.1after modification, restart the Redis server. ~sudo/etc/init.d/redis-Server restartstopping Redis-server:redis-server. Starting Redis-server:redis-server. Log in to Redis server without using a password~ redis-Cliredis127.0.0.1:6379> Keys *(Error) ERR operation not permitted found to be able to login, but could not execute command.

We check Redis's network listening port to check Redis server occupancy Port~ netstat-nlt|grep 6379TCP0      0 0.0.0.0:6379            0.0.0.0:*Listen we see from between the network listening from127.0.0.1:3306Become0 0.0.0.0:3306, which means that Redis has allowed remote login access.

Through the above operation, we will be the Redis database server, Linux ubuntu system installation completed
