## **Linux系统安装 memcached** ##

### **1.首先要先安装libevent库。** ###

yum install libevent libevent-devel

### **2.源码安装memcached** ###

**\#** wget 在线下载工具

yum install -y wget**\#** 在线下载源码

wget http://memcached.org/files/memcached-1.5.16.tar.gz

tar xf memcached-1.5.16.tar.gz

cd memcached-1.5.16、**\#** 配置

./configure --prefix=/usr/local/lamp/memcached

make

make install

### **3. 运行memcached** ###

/usr/local/lamp/memcached/bin/memcached -d -m 64M -u root -p 11211 -c 256

### **4.查看memcached是否运行** ###

ps aux | grep memcached

## **使用PHP代码操作memcached** ##

### **1. 下载并安装libmemcached** ###

cd /root/software

wget https://launchpad.net/libmemcached/1.0/1.0.18/+download/libmemcached-1.0.18.tar.gz

tar xf libmemcached-1.0.18.tar.gz

cd libmemcached-1.0.18

./configure --prefix=/usr/local/libmemcached --with-memcached

make

make install

### **2.安装memcached扩展** ###

cd /root/software

wget https://pecl.php.net/get/memcached-3.1.3.tgz

tar xf memcached-3.1.3.tgz

cd memcached-3.1.3

/usr/local/lamp/php/bin/phpize

./configure --with-php-config=/usr/local/lamp/php/bin/php-config \\

\--with-libmemcached-dir=/usr/local/libmemcached --disable-memcached-sasl

make

make install

### **3.修改php.ini添加memcached扩展** ###

echo "extension=memcached.so" >> /usr/local/lamp/php/lib/php.ini

### **4.重启apache服务器** ###

service httpd restart

### **5.写PHP代码操作memcached** ###

查看php手册：[https://www.php.net/manual/zh/book.memcached.php][https_www.php.net_manual_zh_book.memcached.php]

**<?php**

$m = **new** Memcached();

$m->addServer('localhost', 11211);

$m->set("username","张三");

$username = $m->get("username");**echo** $username;

# **Linux系统安装mongodb** #

### **1. 下载并安装mongo** ###

官网：[https://www.mongodb.com/download-center/community][https_www.mongodb.com_download-center_community]

wget https://fastdl.mongodb.org/linux/mongodb-linux-x86\_64-4.0.10.tgz

tar xf mongodb-linux-x86\_64-4.0.10.tgz**\#** 拷贝到指定目录

mv mongodb-linux-x86\_64-4.0.10 /usr/local/lamp/mongodb

### **2.创建MongoDB数据存放文件夹和日志记录文件夹** ###

cd /usr/local/lamp/mongodb

mkdir -p data/db

mkdir -p data/logs

### **3.创建MongoDB运行时使用的配置文件** ###

cd /usr/local/lamp/mongodb/bin

vim mongodb.conf

*  添加以下内容

dbpath = /usr/local/lamp/mongodb/data/db \#数据文件存放目录

logpath = /usr/local/lamp/mongodb/data/logs/mongodb.log \#日志文件存放目录

port = 27017 \#端口

fork = true \#以守护程序的方式启用，即在后台运行**\#**auth=true *\#**需要认证。如果放开注释，就必须创建**MongoDB**的账号，使用账号与密码才可远程访问*

bind\_ip=0.0.0.0 \#允许远程访问，或者直接注释，127.0.0.1是只允许本地访问

### **4.启动mongodb** ###

cd /usr/local/lamp/mongodb/bin

./mongod  -f  mongodb.conf

*  查看mongodb是否运行

ps aux | grep mongodb

*  关闭mongodb

./mongod  --shutdown -f mongodb.conf

### **5.连接mongo并操作** ###

官网：[https://docs.mongodb.com/manual/crud/][https_docs.mongodb.com_manual_crud]

cd /usr/local/lamp/mongodb/bin

./mongo

# **使用PHP代码操作mongodb** #

### **1.安装mongodb扩展** ###

wget https://pecl.php.net/get/mongodb-1.5.5.tgz

tar xf mongodb-1.5.5.tgz

cd mongodb-1.5.5

/usr/local/lamp/php/bin/phpize

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

make

make install

echo "extension=mongodb.so" >> /usr/local/lamp/php/lib/php.ini

service httpd restart

### **2.写PHP代码操作mongodb** ###

官网：[https://docs.mongodb.com/manual/crud/][https_docs.mongodb.com_manual_crud]

[https://docs.mongodb.com/ecosystem/drivers/php/][https_docs.mongodb.com_ecosystem_drivers_php]

1.  将php环境保存到环境变量中

vim /etc/profile** \#** 最后一行添加

export PATH=$PATH:/usr/local/lamp/php/bin/** \#** 保存退出** \#** 重写加载环境变量文件

source /etc/profile

1.  安装php的openssl扩展（访问https连接）

**\#** 安装扩展依赖

yum install openssl openssl-devel**\#** 进入到扩展文件源码目录

cd /root/software/php-7.2.1/ext/openssl**\#** 使用phpize生成configure文件

/usr/local/lamp/php/bin/phpize**\#** 配置

./configure --with-openssl --with-php-config=/usr/local/lamp/php/bin/php-config**\#** 编译安装

make

make install**\#** 添加扩展到php.ini

echo "extension=openssl.so" >> /usr/local/lamp/php/lib/php.ini

1.  安装git（PHP扩展包放在git上的）

yum install -y git

1.  安装composer

**\#** 安装依赖

yum install zip unzip**\#** 下载

php -r "copy('https://install.phpcomposer.com/installer', 'composer-setup.php');"

php composer-setup.php

php -r "unlink('composer-setup.php');"**\#** 移动 composer.phar，这样 composer 就可以进行全局调用：

mv composer.phar /usr/local/bin/composer**\#** 配置中国镜像

composer config -g repo.packagist composer https://packagist.phpcomposer.com**\#** 查看镜像设置

composer config -gl

1.  下载mongodb扩展

composer require mongodb/mongodb

1.  写PHP代码操作mongodb

$client = **new** MongoDB\\Client();

$db = $client->test;

*\# crud**操作*

## **Linux下的Redis安装和使用** ##

### **Redis服务安装** ###

1.  下载redis源码

wget [http://download.redis.io/releases/redis-5.0.3.tar.gz][http_download.redis.io_releases_redis-5.0.3.tar.gz]

1.  安装redis

tar xf redis\-5.0.3.tar.gz    *//**解压*

cd redis\-5.0.3*//**不需要配置参数不需要执行**./configure*

make && make install*//**编译**&&**安装*

1.  将redis设置为系统服务

cp ./utils/redis\_init\_script /etc/init.d/redis

vim /etc/init.d/redis    //修改红框处的代码

修改redis.conf配置文件

mkdir /etc/redis  //创建/etc/redis目录

cp ./redis.conf /etc/redis/redis.conf

vim/etc/redis/redis.conf

//将redis配置文件复制到redis

//设置为守护进程,以后台方式运行

使用service redis start命令启动redis服务.

1.  将redis服务设置为开机启动

chkconfig *--add redis*

chkconfig *--level 345 redis on*
