php redis连接数过多解决办法（Yii,predis,phpredis等）

Yii redis 持久配置

   'redis' => [
            'class' => 'yii\redis\Connection',
            'hostname' => '127.0.0.1',
            'retries' => 3,
            'port' => 6379,
            'password' => '',
            'socketClientFlags' => STREAM_CLIENT_CONNECT | STREAM_CLIENT_PERSISTENT,
        ],

predis redis 持久配置

  $client = new \Predis\Client([
            'scheme' => 'tcp',
            'host' => $redis->hostname,
            'port' => $redis->port,
            'password' => $redis->password,
            'persistent'=>true,
        ]);

phpredis redis 持久配置

$redis->pconnect('127.0.0.1', 6379);

nginx/python/mysql/fpm/go连接数解决办法

centos Redis 安装

make data dir for redis

mkdir /data/redis
chown -R redis:redis /data/redis

modify config /etc/redis.conf

daemonize yes
dir /data/redis/
appendonly yes
requirepass mypassword

restart

systemctl enalbe redis
systemctl start redis

amazon aws linux下python环境安装

允许远程通过密码登录

给root设置一个密码，允许远程通过密码登录

chmod 400 xxx.pem
ssh -i xxx.pem ec2-user@host-ip    
sudo passwd root
sudo su -
vim /etc/ssh/sshd_config

/etc/ssh/sshd_config内容如下

PermitRootLogin yes
PasswordAuthentication yes
UsePAM yes

然后

service sshd reload

开启epel

amazon aws如果采用redhat需要额外收授权费，目前aws官方2014.3基于centos 6，许多软件版本较旧，可以通过epel软件仓库安装一些新软件

yum-config-manager --enable epel
yum update

安装基本环境

yum groupinstall "Development tools" -y
yum install openssl-devel libxslt-devel libxml2-devel libffi-devel -y

安装mysql客户端

vim /etc/yum.repos.d/MariaDB.repo

# MariaDB 5.5 CentOS repository list - created 2014-09-13 05:43 UTC
# http://mariadb.org/mariadb/repositories/
[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/5.5/centos6-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1

安装MariaDB客户端

yum install MariaDB-client mysql-devel -y

安装redis客户端

rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm
yum-config-manager --enable remi
yum install redis -y

安装mongodb客户端

vim /etc/yum.repos.d/mongodb.repo

[mongodb]
name=MongoDB Repository
baseurl=http://downloads-distro.mongodb.org/repo/redhat/os/x86_64/
gpgcheck=0
enabled=1

安装mongodb客户端

yum update
yum install mongodb-org-shell -y

安装python环境

# yum install centos-release-SCL (aliyun only)
yum install python27*
yum install freetype-devel libjpeg-devel libpng-devel
# scl enable python27 bash (aliyun only)
virtualenv --no-site-packages /data/pyenv
source /data/pyenv/bin/activate
pip install redis cryptography sqlalchemy flask simplejson mongoengine python-amazon-product-api scrapy mysql-python gunicorn gevent

安装glusterfs客户端

#install glusterfs repo
wget -P /etc/yum.repos.d http://download.gluster.org/pub/gluster/glusterfs/LATEST/EPEL.repo/glusterfs-epel.repo
#fix it for amazon linux
sed -i 's/$releasever/6/g' /etc/yum.repos.d/glusterfs-epel.repo 

#install glusterfs
yum install -y glusterfs-fuse

#setup fstab
echo "172.31.42.77:/pcvol /data_pcvol glusterfs defaults,noatime 0 0" >> /etc/fstab

#mount
mkdir /data_pcvol
mount -a
ls /data_pcvol

挂载日志磁盘

lsblk
mkfs -t ext4 /dev/xvdf
echo '/dev/xvdf       /data_log   ext4    defaults,nofail        0       2' >> /etc/fstab
mkdir /data_log
mount -a

ubuntu安装php的redis扩展

下载安装扩展

首先下载包，http://pecl.php.net/package/redis

sudo aptitude install php5-dev
sudo wget http://pecl.php.net/get/redis-2.2.5.tgz
sudo tar zxf redis-2.2.5.tgz 
cd redis-2.2.5/
sudo phpize
sudo ./configure
sudo make
sudo make install

修改ini配置

sudo vim /etc/php5/fpm/conf.d/redis.ini

extension=redis.so

测试运行

sudo php5-fpm -t
sudo php5-fpm -m
sudo service php5-fpm reload
