Redis series 3: ThinkPHP uses redis

1、redis Server configuration authentication password

（1） Configure through the configuration file
Open profile /usr/local/redis/etc/redis.conf find
#requirepass foobared
Remove the comment before the line , And change the password to the desired one , Save the file
requirepass myRedis
restart redis

Try to login at this time redis, Find out you can get on , However, the execution of specific commands is a prompt operation, which is not allowed

1.  redis-cli -h 127.0.0.1 -p 6379  
2.  redis 127.0.0.1:6379>  
3.  redis 127.0.0.1:6379> keys *  
4.  (error) ERR operation not permitted  
5.  redis 127.0.0.1:6379> select 1  
6.  (error) ERR operation not permitted  
7.  redis 127.0.0.1:6379[1]>   

Try to login with password and execute specific command. You can see that it can be executed successfully

1.  redis-cli -h 127.0.0.1 -p 6379 -a myRedis  
2.  redis 127.0.0.1:6379> keys *  
3.  1) "myset"  
4.  2) "mysortset"  
5.  redis 127.0.0.1:6379> select 1  
6.  OK  
7.  redis 127.0.0.1:6379[1]> config get requirepass  
8.  1) "requirepass"  
9.  2) "myRedis"  

2、redis The server configures external access

This shows that it is in the protection mode , see Redis You can understand , Connect Redis Only through local （127.0.0.1） To connect , Instead of using the Internet IP（192.168.1.x） To connect , If necessary, please modify the configuration file redis.conf

Solution

Get into Redis Directory open Redis.conf The configuration file

1> Comment out bind

#bind 127.0.0.1

2> Protection mode is disabled

protected-mode no

3、 To configure thinkphp To configure redis Information

	'DATA_CACHE_PREFIX' => 'Redis_',// Cache prefix 
 	'DATA_CACHE_TYPE'=>'Redis',// The default dynamic cache is Redis
 	'DATA_CACHE_TIMEOUT'=>'1000',
 	'REDIS_RW_SEPARATE' => true, //Redis Read / write separation  true  Turn on 
 	'REDIS_HOST'=>'IP Address ', //redis The server ip, Multiple sets are separated by commas ; When read-write separation is on , The first one is responsible for writing , Other [ Random ] Responsible for reading ;
 	'REDIS_PORT'=>'6379',// Port number 
 	'REDIS_TIMEOUT'=>'1000',// Timeout time 
 	'REDIS_PERSISTENT'=>false,// Long connection or not  false= Short connection 
 	'REDIS_AUTH_PASSWORD'=>'password',//AUTH The authentication code 

4、demo

            $Cache = Cache::getInstance('Redis');
            $Cache->set('name2','easdfasd',6400);  //  cache name data 
            $value = $Cache->get('name2');  //  Get cached name data 
            var_dump( $value);
            exit();

Error message ：

thinkphp Use redis Authentication cannot be used when caching
I am using thinkphp When Find out if you are using redis cache Set up the authentication redis Can connect successfully But not set operation , The inspection found that there was no certification $redis->auth This step does not , So the official Redis.class.php If not , We can add it ourselves , In the constructor section 29 That's ok Change the previous code to ：
The code is as follows ：

$options=array\_merge(array{(}^{\prime }hos{t}^{\prime }=>C{(}^{\prime }REDIS\_HOS{T}^{\prime }){:}^{\prime }127.0.0.1^{\prime }{,}^{\prime }por{t}^{\prime }=>C{(}^{\prime }REDIS\_POR{T}^{\prime }):6379{,}^{\prime }timeou{t}^{\prime }=>C{(}^{\prime }DATA\_CACHE\_TIMEOU{T}^{\prime }):false{,}^{\prime }persisten{t}^{\prime }=>false,),$options);

Add a line ‘auth’ => C(‘REDIS_AUTH_PASSWORD’) C(‘REDIS_AUTH_PASSWORD’):null,//auth Authenticated password , Instead

$options=array\_merge(array{(}^{\prime }hos{t}^{\prime }=>C{(}^{\prime }REDIS\_HOS{T}^{\prime }){:}^{\prime }127.0.0.1^{\prime }{,}^{\prime }por{t}^{\prime }=>C{(}^{\prime }REDIS\_POR{T}^{\prime }):6379{,}^{\prime }timeou{t}^{\prime }=>C{(}^{\prime }DATA\_CACHE\_TIMEOU{T}^{\prime }):false{,}^{\prime }aut{h}^{\prime }=>C{(}^{\prime }REDIS\_AUTH\_PASSWOR{D}^{\prime })C{(}^{\prime }REDIS\_AUTH\_PASSWOR{D}^{\prime }):null,//authrecognizeProveOfThe\; secret{code}^{\prime }persisten{t}^{\prime }=>false,),$options);

So you can options Read the password of whether to enable authentication in , Then add a judgment
After this code
$this->handler = new Redis;
$options[‘timeout’] === false
$this->handler->$func($options[‘host’], $options[‘port’]) :
$this->handler->$func($options[‘host’], $options[‘port’], KaTeX parse error: Undefined control sequence: \[ at position 8: options\̲[̲'timeout'\]); …this->options[‘auth’]!==null)
{
$this->handler->auth($this->options[‘auth’]); // Description configuration redis Authentication configuration password Need certification
}
overall , The construction method is changed as follows ：

public function __construct($options=array()) {
if ( !extension_loaded(‘redis’) ) {
E(L(‘_NOT_SUPPORT_’).‘:redis’);
}
$options=array\_merge(array{(}^{\prime }hos{t}^{\prime }=>C{(}^{\prime }REDIS\_HOS{T}^{\prime }){:}^{\prime }127.0.0.1^{\prime }{,}^{\prime }por{t}^{\prime }=>C{(}^{\prime }REDIS\_POR{T}^{\prime }):6379{,}^{\prime }timeou{t}^{\prime }=>C{(}^{\prime }DATA\_CACHE\_TIMEOU{T}^{\prime }):false{,}^{\prime }aut{h}^{\prime }=>C{(}^{\prime }REDIS\_AUTH\_PASSWOR{D}^{\prime })C{(}^{\prime }REDIS\_AUTH\_PASSWOR{D}^{\prime }):null,//authrecognizeProveOfThe\; secret{code}^{\prime }persisten{t}^{\prime }=>false,),$options);

$this->options = $options;
KaTeX parse error: Undefined control sequence: \[ at position 14: this->options\̲[̲'expire'\] = is…options[‘expire’]) $options[‘expire’] : C(‘DATA_CACHE_TIME’);
KaTeX parse error: Undefined control sequence: \[ at position 14: this->options\̲[̲'prefix'\] = is…options[‘prefix’]) $options[‘prefix’] : C(‘DATA_CACHE_PREFIX’);
KaTeX parse error: Undefined control sequence: \[ at position 14: this->options\̲[̲'length'\] = is…options[‘length’]) $options[‘length’] : 0;
$func = $options[‘persistent’] ‘pconnect’ : ‘connect’;
$this->handler = new Redis;
$options[‘timeout’] === false
$this->handler->$func($options[‘host’], $options[‘port’]) :
$this->handler->$func($options[‘host’], $options[‘port’], KaTeX parse error: Undefined control sequence: \[ at position 8: options\̲[̲'timeout'\]); …this->options[‘auth’]!=null)
{
$this->handler->auth($this->options[‘auth’]); // Description configuration redis Authentication configuration password Need certification
}
}

Then add... To the configuration file “REDIS_AUTH_PASSWORD”=>“redis The authentication code ” that will do
