1.1 hiredis
1.2 redis官网下载+安装+编译
如果下的是7的版本,不需要下hiredis.直接编译即可。
bash
$ wget http://download.redis.io/releases/redis-7.2.0.tar.gz
$ tar -zxvf redis-7.2.0.tar.gz
# -z:gzip x:解压 v:显示所有过程 f:文件
$ cd redis-7.2.0
$ make
$ make install
$ redis-server
$ redis-cli
默认的安装目录:/usr/local/redis
/usr/
/usr/local/include
/usr/local/lib
/usr/local/lib/pkgconfig
错误提示:
1./bin/sh: 1: pkg-config: not found
apt-get install pkg-config
make distclean && make
srv/ftp/
bash
#1.ubuntu 下安装tftp
apt-get install vsftpd
apt-get install ftp
#2.修改配置文件
vim /etc/vsftpd.conf
local_enables=YES
write_enable=YES
anonymous_enable=YES
anon_mkdir_write_enable=YES //允许匿名用户在FTP上创建目录
anon_upload_enable=YES //允许匿名用户在FTP服务器上上传文件
anon_other_write_enable=YES //开启匿名用户的其他写权限
#不要用root 或者 anonymous访问
1.1make 之前
|--------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------|---|
| | 5.0.14 | 7.2.0 | |
| make | 1.deps/jemalloc 多了lib文件夹 2.deps/lua/ 多了.o文件 3.src 下多了.o文件 | make test | |
| 两个版本的对比: | | 1.deps/fpconv 2.deps/hdr_histogram 3.deps/hiredis :ssl sockcompat 4.src/commands 5.src/ 多了好多函数 | |
| make install | 之前bin,lib,inlcude3个文件夹下什么都没有。 安装后: 1.redis-5.2.0/src下有6个应用程序redis-server 2./usr/local/bin 下有6个应用程序redis-server 3./usr/local/include 无 4. /usr/local/lib 无 /usr/local/lib/pkgconfig | 1.redis-7.2.0/src下有6个应用程序redis-server 只保留一个版本。 2./usr/local/bin下有6个应用程序redis-server 3./usr/local/include 无 4. /usr/local/lib 无 /usr/local/lib/pkgconfig | |
| | 所有文件在目录下: /home/tang/redis-5.0.14 | | |
| 配置文件: | /home/tang/redis-5.0.14/redis.conf | | |
| 日志文件: | /var/log/redis/redis-server.log | | |
1.make 前后的对比
2.5版本和7版本的对比
2.启动服务器和客户端
2.1 src下启动
cd redis7/src
redis-server
redis-cli
bash
./src/redis-cli
#带Host、Port、Auth连接: ./src/redis-cli -h 127.0.0.1 -p 6379 -a 123456
2.2 修改环境变量
/etc/profile
3.redis 自带的hiredis基本用法
https://github.com/redis/hiredis
bash
#1.创建一个放工程文件的文件夹 与redis安装包同级别
mkdir /home/tang/redisprj
#2.修改环境变量
vim ~/.bashrc
source .bashrc
vim /etc/profile
#2.1 动态库+静态库链接库文件
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/tang/redis-7.2.0/deps/hiredis
export LIBRARY_PATH=$LIBRARY_PATH
#2.2 头文件
#gcc头文件
export C_INCLUDE_PATH=/usr/include
#g++找到头文件的路径
export CPLUS_INCLUDE_PATH=$CPLUS_INCLUDE_PATH:/usr/include
#2.3 可执行文件
export PATH =$PATH:/home/tang/redis-7.2.0/src
# 安装软件放在 /usr/local/include下
- 编写一个最基本的c文件。
1.1编写test_main00.c,只输出一个字符串。
bash
#include<stdio.h>
int main()
{
printf("my test_main.c\n");
return 0;
}
1.2编译运行,看是否正常输出。
bash
编译运行
gcc test_main00.c -o testmain # -o 编译后的应用程序名,可以有后缀也可以没有后缀
./testmain # 运行程序 ./表示当前文件夹
2.编写1个调用hiredis set和get 的c文件
2.1 编写文件
bash
//1.连接
//2.发送
//3.处理返回
//4.清空
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <hiredis.h>
void main()
{
redisContext *pc = redisConnect("127.0.0.1", 6379); //1.连接
if (pc == NULL || pc->err)
{
if (pc)
{
printf("Error: %s\n", pc->errstr);
}
else
{
printf("Can't allocate redis context\n");
}
}
redisReply *psetreply;
psetreply= redisCommand(pc, "PING"); //2.发送PING
printf("PING: %s\n", psetreply->str);
freeReplyObject(psetreply);
psetreply= redisCommand(pc, "SET %s %s", "foo", "hello world"); //2.发送SET
printf("SET: %s\n", psetreply->str);
freeReplyObject(psetreply);
psetreply= redisCommand(pc, "SET %b %b", "bar", (size_t) 3, "hello", (size_t) 5); //2.发送
printf("SET (binary API): %s\n", psetreply->str);
freeReplyObject( psetreply);
// reply = redisCommand(context, "SET foo %s", value);
// reply = redisCommand(context, "SET foo %b", value, (size_t) valuelen);
// reply = redisCommand(context, "SET key:%s %s", myid, value);
//4.清空
redisFree(pc);
//5.get();
}
bash
//1.连接
//2.发送
//3.处理返回
//4.清空
void get()
{
redisContext *c = redisConnect("127.0.0.1", 6379); //1.连接
if (c == NULL || c->err)
{
if (c)
{
printf("Error: %s\n", c->errstr);
}
else
{
printf("Can't allocate redis context\n");
}
}
redisReply *pgetreply;
pgetreply= redisCommand(c, "GET foo"); //2.GET foo
printf("GET foo: %s\n", pgetreply->str);
freeReplyObject(pgetreply);
pgetreply= redisCommand(c, "INCR counter"); //2.GET
printf("INCR counter: %lld\n", pgetreply->integer);
freeReplyObject(pgetreply);
pgetreply= redisCommand(c,"INCR counter");
printf("INCR counter: %lld\n", pgetreply->integer);
freeReplyObject(pgetreply);
redisReply *reply ;
/* Create a list of numbers, from 0 to 9 */
reply = redisCommand(c,"DEL mylist");
freeReplyObject(reply);
for (int j = 0; j < 10; j++) {
char buf[64];
snprintf(buf,64,"%u",j);
reply = redisCommand(c,"LPUSH mylist element-%s", buf);
freeReplyObject(reply);
}
/* Let's check what we have inside the list */
reply = redisCommand(c,"LRANGE mylist 0 -1");
if (reply->type == REDIS_REPLY_ARRAY)
{
for ( int j = 0; j < reply->elements; j++) {
printf("%u) %s\n", j, reply->element[j]->str);
}
}
//4.清空
redisFree(c);
}
2.2 编译输出
bash
gcc redis_mainsetget01.c -o redis_mainsetget01 -L/home/tang/redis-7.2.0/deps/hiredis -lhiredis
2.3 远程连接
redis-cli -h [IP地址] -p [PORT端口号] -a [密码password]
