Memcached php docker compose

Docker local deployment memcached comes with the docker compose deployment memcached/elasticsearch/kibana/php/nginx script

Memcached is a general distributed memory caching system. It is usually used to speed up dynamic database driven websites by caching data and objects in RAM to reduce the number of times that external data sources (such as databases or API s) must be read.

The Memcached API provides a very large hash table distributed across multiple machines. When the table is full, subsequent inserts cause old data to be purged in the least recently used order. Applications using Memcached typically tier requests and additions into RAM and then return to slower backup storage, such as databases.

2, Why use memcached

In the architecture of a single server, memcached is used to reduce the pressure on the database. For infrequently updated data, it is not necessary to request the database every time.

Similarly, the file cache I wrote before also works. However, the local file cache has a disadvantage that it cannot be used across projects. I can only read and write the cache I use within my own framework.

If my project is multi server or multi terminal, and neither api project nor web project is implemented in the same language, then use the file

3, Deployment installation

1. Version selection

Note that if you use latest, it is the default latest version. At present, the latest version is 1.6.

However, from the perspective of actual projects, most companies do not use the latest version in their production environment, so they must choose their own version according to the actual situation.

The version I choose here is 1.4.32.

Again, the version number in any environment is very important. You can’t use the latest version by default.

2. Command line direct installation

docker run -p 11211:11211 --name memcache memcached:1.4.32

If you do not specify the version after the colon, the default is the latest version.

(base) xxxx@xxxx ~ % telnet 127.0.0.1 11211 Trying 127.0.0.1. Connected to localhost. Escape character is '^]'.

3. Docker compose installation

Command line installation has some disadvantages, such as

• Team members are hard to copy
• Poor environment configuration and storage
• The complete set of environment is not easy to maintain

Docker compose can solve these shortcomings.

As like as two peas, docker-compose maintains a docker-compose.yml file, which integrates all the project environments together, so that all the project members have the same environmental configuration.

memcached: image: memcached:1.4.32 ports: - 11211:11211

At present, the local environment of docker compose I use includes

The local configuration is as follows, and the pro test is available.

version: "3" services: memcached: image: memcached:1.4.32 ports: - 11211:11211 elastic: image: elasticsearch:6.7.0 # image: elasticsearch:7.9.3 ports: - "9200:9200" environment: - bootstrap.system_call_filter=false # - node.name=node-1 # - cluster.initial_master_nodes=node-1 volumes: # - /opt/docker/elasticsearch/data:/usr/share/elasticsearch/data - ../elasticsearch-local/data:/usr/share/elasticsearch/data networks: web: ipv4_address: 172.25.0.3 kibana: image: kibana:6.7.0 # image: kibana:7.9.3 environment: - I18N_LOCALE=zh-CN - ELASTICSEARCH_HOSTS=http://172.25.0.3:9200 - ELASTICSEARCH_URL=http://172.25.0.3:9200 ports: - "5601:5601" networks: - web php: image: crunchgeek/php-fpm:7.0 volumes: - ./yii_env.php:/var/www/yii_env.php - ./php.ini:/usr/local/etc/php/php.ini - ./:/var/www/html networks: - web web: image: nginx ports: - "8001-8009:8001-8009" volumes: - ./yii_env.php:/var/www/yii_env.php - ./:/var/www/html - ./default:/etc/nginx/conf.d/default.conf - ./localcerts:/etc/nginx/certs networks: - web networks: web: ipam: driver: default config: - subnet: "172.25.0.0/16"

4, Summary

• It is recommended to use docker in the local environment, which is easy to deploy without burden.
• docker is not recommended for online environment, and performance loss can not be ignored.

Docker Php Ext to Install Memcached

Let us take a look at installing Memcached using the Docker Php ext in detail.

what is docker Php ext?

This command is used to activate the PHP extension. The PHP extension is not started by default when the user uses pecl to install it. They must configure this extension in PHP if they want to use it.

Memcached and docker Php ext

Memcached is a caching system that can improve back-end database performance. It can temporarily store information in memory. And, It can retain frequently or recently requested records. They reduce the number of direct requests to databases in this way.

Anyone can use the docker-php-ext-* commands to complete the docker PHP ext to install Memcached and process. It is critical to check out the source. The installation must begin with a Base installation process. Note that it is assumed that the user has already completed the installation of the necessary items to run the extension.

Base Installation for docker Php ext install Memcached

The user can run the following command after installing all of the necessary items for the Memcached extension.

RUN git clone -b php7 https://github.com/php-memcached-dev/php-memcached /usr/src/php/ext/memcached \
&& docker-php-ext-configure /usr/src/php/ext/memcached \ —disable-memcached-sasl \
&& docker-php-ext-install /usr/src/php/ext/memcached \
&& rm -rf /usr/src/php/ext/memcached

The repository will be cloned using this block. So the user must configure and install the extension before cleaning up.

Requirements

To build the extension for Docker Php ext install Memcached, the user will most likely need to install two packages. They can add and remove by doing the following: ENV MEMCACHED_DEPS zlib-dev libmemcached-dev cyrus-sasl-dev git
RUN set -xe \
&& apk add —no-cache libmemcached-libs zlib \
&& apk add —no-cache \
—virtual .memcached-deps \
$MEMCACHED_DEPS \
&& git clone -b php7 https://github.com/php-memcached-dev/php-memcached /usr/src/php/ext/memcached \
&& docker-php-ext-configure /usr/src/php/ext/memcached \
—disable-memcached-sasl \
&& docker-php-ext-install /usr/src/php/ext/memcached \
&& rm -rf /usr/src/php/ext/memcached \
&& apk del .memcached-deps

FROM php:7.4.28-apache
RUN apt-get install -y libz-dev libmemcached-dev && \
apt-get install -y memcached libmemcached-tools && \
pecl install memcached && \
docker-php-ext-enable memcached

And after this the user can start the daemon using: /etc/init.d/memcached start .

Alternative method

Firstly, use the pecl to install these extensions. The user must then use the docker command to open the extension.

RUN apk update && apk add —no-cache/
autoconf g++ make libmemcached-dev/
&& pecl install memcached/
&& docker-php-ext-enable memcached/

The installation is successful. To verify that the redis, Memcached, and swoole extensions have been installed, run php -m.

Conclusion

To conclude the process of installing Memcached with the docker Php extension is extremely easy to do. A user can manage and complete the installation steps in a few simple steps. And, the extension will help to manage and improve back-end database performance.
