centos下docker的lnmp的环境，各部件独立容器

本篇文章主要是结合我之前面试的各种经历和实战开发中遇到的问题解决经验整理的，希望这篇《centos下docker的lnmp的环境，各部件独立容器》对你有很大帮助！欢迎收藏，分享给更多的需要的朋友学习~

docker安装

卸载

yum remove docker docker-common docker-selinux docker-engine

安装docker需要环境

yum install -y yum-utils device-mapper-persistent-data lvm2

配置安装reps

yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

#更新yum包
yum makecache fast

安装docker 并启动

yum install docker-ce
systemctl start docker

docker mysql 容器

安装mysql

mkdir -p /web/docker/mysql/logs
mkdir -p /web/docker/mysql/pid
mkdir -p /web/docker/mysql/data
mkdir -p /web/docker/mysql/conf

docker pull mysql:5.6.37

宿主机上/web/docker/mysql/conf/my.cnf 配置文件

[mysqld]
slow_query_log = ON
slow_launch_time=5

#pid-file        = /web/docker/mysql/pid/mysqld.pid
#socket          = /web/docker/mysql/pid/mysqld.sock
datadir         = /web/docker/mysql/data
log-error       = /web/docker/mysql/logs/error.log
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0

启动并自定义配置文件和数据目录

docker run -p 3306:3306 --name mysql-server -v /web/docker/mysql/conf:/etc/mysql/mysql.conf.d -v /web/docker/mysql:/web/docker/mysql -e MYSQL_ROOT_PASSWORD=123345 -d mysql:5.6.37

注意这里的--name mysql-server 后续有用，因为data是宿主机上，所以下次可以省略-e MYSQL_ROOT_PASSWORD=123345

docker php 容器

安装php

docker pull php:5.6.31-fpm

启动php-fpm

docker run --name php-fpm-1 --rm -p 9000:9000 -v /web/docker/nginx/www1:/var/www/html -d php:5.6.31-fpm

安装iconv、mcrypt、gd和pdo_mysql扩展

docker exec -it container_id /bin/bash
apt-get update
apt-get install -y libfreetype6-dev libjpeg62-turbo-dev libmcrypt-dev libpng12-dev
docker-php-ext-install -j$(nproc) iconv mcrypt
docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/
docker-php-ext-install -j$(nproc) gd
exit

container_id 是你php-fpm启动后的容器id

安装redis、xdebug、memcache扩展

pecl install redis-3.1.3
pecl install xdebug-2.5.5
docker-php-ext-enable redis xdebug

apt-get install -y libmemcached-dev zlib1g-dev
pecl install memcached-2.2.0
docker-php-ext-enable memcached

停止和重启php-fpm重启

docker stop container_id
docker start container_id

注意这里的/var/www/html是php-fpm的读取源码默认位置，请勿修改后续nginx里有配置相关对应

docker nginx 容器

安装nginx

docker pull nginx:1.12.1

启动nginx，并关联mysql和php容器

mkdir -p /web/docker/nginx/logs
mkdir -p /web/docker/nginx/pid
mkdir -p /web/docker/nginx/www1
mkdir -p /web/docker/nginx/conf

docker run --name nginx-server-1 --link php-fpm-1:php-fpm --link mysql-server:mysql-server -v /web/docker/nginx/conf/nginx.conf:/etc/nginx/nginx.conf -v /web/docker/nginx:/web/docker/nginx -p 80:80 -d nginx:1.12.1

注意这里的/etc/nginx/nginx.conf是nginx的读取源码默认配置文件

/web/docker/nginx/www1/index.php

/web/docker/nginx/www1/index.html

nginx is working!
