LNMP环境下安装Redis，以及php的redis扩展

1.下载

sudo wget http://download.redis.io/releases/redis-4.0.9.tar.gz

2.解压

sudo tar zvxf redis-4.0.9.tar.gz 

3.重命名

sudo mv redis-4.0.9/ redis

4.编译

cd redis
sudo make
sudo make test
sudo make install

有可能会出现

You need tcl 8.5 or newer 

那就去安装

sudo wget https://downloads.sourceforge.net/tcl/tcl8.6.8-src.tar.gz
sudo tar xzvf tcl8.6.8-src.tar.gz  -C /usr/local/  
cd  /usr/local/tcl8.6.1/unix/  
sudo ./configure  
sudo make  
sudo make install   

成功了

jiqing@jiqing-pad:~$ redis-cli
127.0.0.1:6379> set name jack
OK
127.0.0.1:6379> get name
"jack"
127.0.0.1:6379> 

如果出现

Could not connect to Redis at 127.0.0.1:6379: Connection refused

在安装好redis扩展 尝试连接redis时，客户端打不开，原因是需要先开启服务端，这需要先配置——

A.找到redis.conf 并修改 daemonize no 为 daemonize yes ，这样就可以默认启动就后台运行

 vi /etc/redis.conf

B.开启客户端要确保服务端启动

redis-server /etc/redis.conf

 

安装PHP-redis扩展

1.下载

sudo wget https://pecl.php.net/get/redis-4.0.2.tgz

2.解压

sudo tar -zxvf redis-4.0.2.tgz 

3.找到phpize文件，生成配置

$whereis phpize
phpize: /usr/bin/phpize

在redis-4.0.2文件夹中执行

sudo /usr/bin/phpize 

drwxr-xr-x  2 root root     4096 5月  23 01:57 ./
drwxr-xr-x 10 root root     4096 5月  23 01:57 ../
-rwxr-xr-x  1 root root      837 5月  23 01:57 pear*
-rwxr-xr-x  1 root root      858 5月  23 01:57 peardev*
-rwxr-xr-x  1 root root      774 5月  23 01:57 pecl*
lrwxrwxrwx  1 root root        9 5月  23 01:57 phar -> phar.phar*
-rwxr-xr-x  1 root root    14833 5月  23 01:57 phar.phar*
-rwxr-xr-x  1 root root 48618304 5月  23 01:57 php*
-rwxr-xr-x  1 root root 48473272 5月  23 01:57 php-cgi*
-rwxr-xr-x  1 root root     3325 5月  23 01:57 php-config*
-rwxr-xr-x  1 root root     4534 5月  23 01:57 phpize*

4.配置

sudo ./configure  --with-php-config=/usr/local/php/bin/php-config 

sudo make

sudo make test

这个时候会报一些错误，打开php.ini

 sudo vi /usr/local/php/etc/php.ini 

disable_functions = passthru,exec,system,chroot,chgrp,chown,shell_exec,proc_open,proc_get_status,popen,ini_alter,ini_restore,dl,openlog,syslog,readlink,symlink,popepassthru,stream_socket_server

去除shell_exec,proc_open

sudo make install

5.添加扩展

extension=redis.so

查看

php -m

jiqing@jiqing-pad:/$ php -m |grep redis
redis

已经添加成功了！

进一步测试，

<?php
    $redis = new Redis();
    $redis->connect('127.0.0.1',6379);
    $redis->set('test','hello world!');
    echo $redis->get('test');
?>

hello world!
Process finished with exit code 0

成功！

进一步查看服务开启情况！

jiqing@jiqing-pad:/home/wwwroot/default$ sudo netstat -anp|grep :6379
tcp        0      0 0.0.0.0:6379            0.0.0.0:*               LISTEN      27904/redis-server
