Redis是个高性能的key-value数据库,它的key具有丰富的数据结构:string,hash,list set和sorted set。作为NOSQL,比起memcache之类,不仅仅key数据结构丰富,而且具有持久化的功能,并且能够支持主从复制,,很方便构建集群。

redis高性能很大程度上源于它是个内存型数据库,它的高性能表现在:set操作11w/s,get操作8.1w/s,为了进一步加深对redis的理解总结,我打算写个redis系列的文章。这里主要谈谈redis安装部署及运维维护。

1、下载安装

[root@ ]# wget -c     #下载 
[root@ ]# tar -zxvf redis-2.4.17.tar.gz  #解压 
[root@ ]# cd redis-2.4.17 
[root@ redis-2.4.17]# make  #编译 
[root@ redis-2.4.17]# make install #安装 

安装完毕,常用工具会自动拷贝到/user/loca/bin目录下。做为服务器,我们常常还需要把redis设置成开机自启动,源码包中有个很好用的脚本,执行脚步根据提示输入即可。

[root@ redis-2.4.17]# cd utils/ 
[root@ utils]# ./install_server.sh 
Welcome to the redis service installer 
This script will help you easily set up a running redis server 
 
 
Please select the redis port for this instance: [6379] 
Selecting default: 6379 
Please select the redis config file name [/etc/redis/6379.conf] 
Selected default - /etc/redis/6379.conf 
Please select the redis log file name [/var/log/redis_6379.log] 
Selected default - /var/log/redis_6379.log 
Please select the data directory for this instance [/var/lib/redis/6379] 
Selected default - /var/lib/redis/6379 
Please select the redis executable path [/usr/local/bin/redis-server] 
Copied /tmp/6379.conf => /etc/init.d/redis_6379 
Installing service... 
Successfully added to chkconfig! 
Successfully added to runlevels 345! 
Starting Redis server... 
Installation successful! 

注意执行install_server.sh,需要先进入utils目录,不然脚本会报错,提示找不到相应文件。安装完服务,redis自动启动,可以用ps命令查看到相关信息:

[root@ utils]# ps -ef | grep redis 
root      4554    1  0 10:55 ?        00:00:02 /usr/local/bin/redis-server /etc/redis/6379.conf 
root      4564  2808  0 10:59 pts/0    00:00:00 grep redis 

2、手动启动关闭服务

[root@ utils]# /etc/init.d/redis_6379 stop  #关闭 
[root@ utils]# /etc/init.d/redis_6379 start  #启动 

3、通过客户端命令行工具连接redis服务查看redis相关信息

a)连接

[root@ utils]# redis-cli 

redis 127.0.0.1:6379> 

b)其他指令

redis 127.0.0.1:6379> info  #查看server版本内存使用连接等信息 
 
redis 127.0.0.1:6379> client list  #获取客户连接列表 
 
redis 127.0.0.1:6379> client kill 127.0.0.1:33441 #终止某个客户端连接 
 
redis 127.0.0.1:6379> dbsize #当前保存key的数量 
 
redis 127.0.0.1:6379> save #立即保存数据到硬盘 
 
redis 127.0.0.1:6379> bgsave #异步保存数据到硬盘 
 
redis 127.0.0.1:6379> flushdb #当前库中移除所有key 
 
redis 127.0.0.1:6379> flushall #移除所有key从所有库中 
 
redis 127.0.0.1:6379> lastsave #获取上次成功保存到硬盘的unix时间戳 
 
redis 127.0.0.1:6379> monitor #实时监测服务器接收到的请求 
 
redis 127.0.0.1:6379> slowlog len #查询慢查询日志条数 
(integer) 3 
 
redis 127.0.0.1:6379> slowlog get #返回所有的慢查询日志,最大值取决于slowlog-max-len配置 
 
redis 127.0.0.1:6379> slowlog get 2 #打印两条慢查询日志 
 
redis 127.0.0.1:6379> slowlog reset #清空慢查询日志信息 

通过以上操作,单台服务器基本跑起来了,不过后面的路还很长很长。

MySQL: String Data Types and CollationsMySQL: String Data Types and CollationsMay 09, 2025 am 12:08 AM

The string data types in MySQL include CHAR, VARCHAR, BINARY, VARBINARY, BLOB, and TEXT. The collations determine the comparison and sorting of strings. 1.CHAR is suitable for fixed-length strings, VARCHAR is suitable for variable-length strings. 2.BINARY and VARBINARY are used for binary data, and BLOB and TEXT are used for large object data. 3. Sorting rules such as utf8mb4_unicode_ci ignores upper and lower case and is suitable for user names; utf8mb4_bin is case sensitive and is suitable for fields that require precise comparison.

The best MySQLVARCHAR column length selection should be based on data analysis, consider future growth, evaluate performance impacts, and character set requirements. 1) Analyze the data to determine typical lengths; 2) Reserve future expansion space; 3) Pay attention to the impact of large lengths on performance; 4) Consider the impact of character sets on storage. Through these steps, the efficiency and scalability of the database can be optimized.

MySQLWorkbench, suitable for small to medium-sized environments, easy to use but high resource consumption; 2. Ansible, suitable for multi-server environments, simple but steep learning curve; 3. Custom Python scripts, flexible but need to ensure script security; 4. Puppet and Chef, suitable for large-scale environments, complex but scalable. Scale, learning curve and integration needs should be considered when choosing.
