Centos7下Docker搭建lnmp开发环境流程步骤
docker我已经安装好了,就是该类下的上一篇文章,
想了解docker安装的话自己去看:https://www.zongscan.com/demo333/304.html
docker常用命令:
systemctl start docker # 启动docker systemctl stop docker # 停止docker systemctl status docker # 查看docker状态 systemctl restart docker # 重新启动docker
搭建lnmp环境,下面我们正式开始
所需软件
1. nginx 2. mysql 3. php7.4
lnmp目录:
docker │ └── nginx │ │ └── default.conf #nginx配置文件 │ └── www │ └── obj #项目代码
1.安装nginx
我们可以使用 docker search nginx 命令查找 Docker Hub 上的 nginx 镜像,这里直接拉取官方的镜像
[[email protected] ~]# docker pull nginx
等待下载完成后,我们就可以在本地镜像列表里查到 REPOSITORY 为 nginx 的镜像。
[[email protected] www]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE docker.io/nginx latest 62d49f9bab67 12 days ago 133 MB
创建 nginx 配置:
[[email protected] ~]# cd /docker/nginx [[email protected] ~]# touch default.conf [[email protected] ~]# vim default.conf
server { listen 80; listen [::]:80; server_name localhost; root /docker/www/obj/public; index index.php index.html; location / { try_files $uri $uri/ /index.php?$query_string; } error_page 500 502 503 504 /50x.html; location = /50x.html { root /docker/www/obj/public; } location ~ \.php$ { root /docker/www/obj/public; fastcgi_pass 192.168.1.10:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } }
使用 nginx 镜像开启 nginx 应用容器
[[email protected] ~]# docker run -p 80:80 -d --name nginx -v /docker/nginx/default.conf:/etc/nginx/conf.d/default.conf -v /docker/www:/docker/www --privileged=true nginx
-p 80:80:将容器的80端口映射到主机的80端口
-d 后台运行(守护进程)
--name nginx:将容器命名为nginx
-v 将主机中当前目录下的www挂载到容器的www目录
查看docker目前的容器
[[email protected] ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 8781afd1bf13 nginx "/docker-entrypoin..." About an hour ago Up 17 minutes 0.0.0.0:80->80/tcp nginx
2.安装php
我这里版本为 7.4-fpm,其他版本的可自行选择
[[email protected] ~]# docker pull php:7.4-fpm [[email protected] docker]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE docker.io/nginx latest 62d49f9bab67 12 days ago 133 MB docker.io/php 7.4-fpm 41b17b0f90e6 2 weeks ago 405 MB
使用 php 镜像开启 php-frm 应用容器
[[email protected] docker]# docker run -p 9000:9000 -d --name php -v /docker/www:/docker/www --privileged=true php:7.4-fpm
-p 9000:9000 :将容器的9000端口映射到主机的9000端口
-d 后台运行(守护进程)
--name php:将容器命名为php
-v 将主机中当前目录下的www挂载到容器的www目录
查看容器启动情况:
[[email protected] docker]# docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES cbf73ca0f17c php:7.4-fpm "docker-php-entryp..." About an hour ago Up About an hour 0.0.0.0:9000->9000/tcp php 8781afd1bf13 nginx "/docker-entrypoin..." About an hour ago Up 23 minutes 0.0.0.0:80->80/tcp nginx
到这里,可以看到 nginx 和 php 都运行成功 (STATUS 为 up 说明正在运行)
查看 ip 信息
[[email protected] docker]# docker inspect php | grep "IPAddress" "SecondaryIPAddresses": null, "IPAddress": "192.168.1.10", "IPAddress": "192.168.1.10",
查看 nginx 配置的 php-fpm 服务 ip 是否一致:
location ~ \.php$ { root /docker/www/obj/public; fastcgi_pass 192.168.1.10:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; }
以上配置中 fastcgi_pass 192.168.1.10:9000; 需要与我们查看的 php 容器的 ip 一致。
完成以上配置并且确定容器启动没有问题,可以进行测试:
访问项目obj可能出现目录权限问题,以下是解决方式:
[[email protected] docker]# cd /docker/www [[email protected] www]# chmod -R 777 obj
3.安装mysql
[[email protected] docker]# docker pull mysql [[email protected] docker]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE docker.io/mysql latest 0627ec6901db 6 days ago 556 MB docker.io/nginx latest 62d49f9bab67 12 days ago 133 MB docker.io/php 7.4-fpm 41b17b0f90e6 2 weeks ago 405 MB
配置宿主机的 mysql 配置文件
[[email protected] docker]# vim /etc/my.cnf [client] port = 3306 socket = /tmp/mysql.sock [mysqld] secure_file_priv=/var/lib/mysql port = 3306 socket = /tmp/mysql.sock datadir = /usr/local/mysql/data default_storage_engine = InnoDB performance_schema_max_table_instances = 400 table_definition_cache = 400 skip-external-locking key_buffer_size = 32M max_allowed_packet = 100G table_open_cache = 128 sort_buffer_size = 768K net_buffer_length = 4K read_buffer_size = 768K read_rnd_buffer_size = 256K myisam_sort_buffer_size = 8M thread_cache_size = 16 tmp_table_size = 32M default_authentication_plugin = mysql_native_password lower_case_table_names = 1 sql-mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES explicit_defaults_for_timestamp = true max_connections = 500 max_connect_errors = 100 open_files_limit = 65535 log-bin=mysql-bin binlog_format=mixed server-id = 1 binlog_expire_logs_seconds = 600000 slow_query_log=1 slow-query-log-file=/usr/local/mysql/data/mysql-slow.log long_query_time=3 early-plugin-load = "" innodb_data_home_dir = /usr/local/mysql/data innodb_data_file_path = ibdata1:10M:autoextend innodb_log_group_home_dir = /usr/local/mysql/data innodb_buffer_pool_size = 128M innodb_log_file_size = 64M innodb_log_buffer_size = 16M innodb_flush_log_at_trx_commit = 1 innodb_lock_wait_timeout = 50 innodb_max_dirty_pages_pct = 90 innodb_read_io_threads = 1 innodb_write_io_threads = 1 [mysqldump] quick max_allowed_packet = 500M [mysql] no-auto-rehash [myisamchk] key_buffer_size = 32M sort_buffer_size = 768K read_buffer = 2M write_buffer = 2M [mysqlhotcopy] interactive-timeout
使用 mysql 镜像开启 mysql 应用容器
[[email protected] docker]# docker run -p 3306:3306 -d --name mysql -v /etc/my.cnf:/etc/mysql/my.cnf --privileged=true -e MYSQL_ROOT_PASSWORD=root mysql
-p 3306:3306 :将容器的3306端口映射到主机的3306端口
-d 后台运行(守护进程)
--name mysql:将容器命名为mysql
-v 将主机中的mysql配置挂载到容器的/etc/mysql/my.cnf
进入容器,连接 mysql 配置一个自己的用户,用于项目使用
[[email protected] docker]# docker exec -it mysql bash [email protected]:/#
#连接mysql,密码就是我们在构建容器时镜像设置的MYSQL_ROOT_PASSWORD参数值
[email protected]:/# mysql -uroot -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g.
