1.centos7安裝docker
安裝依賴包
yum install -y yum-utils device-mapper-persistent-data lvm2
添加Docker軟件包源
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
或者使用阿里雲的源 wget http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
安裝Docker CE
yum install docker-ce –y
二進制包地址https://download.docker.com/linux/static/stable/x86_64/
啓動
systemctl start docker
開機啓動
systemctl enable docker
查看Docker信息
docker info
配置docker加速器
curl -sSL https://get.daocloud.io/daotools/set_mirror.sh|sh -s http://bc437cce.m.daocloud.io
2.自定義網絡，生產環境常用，後面創建的容器加入到lnmp網絡
docker network create lnmp
3. 創建mysql容器
這裏採用mysql5.7版本，加上參數--restart always 保證容器在主機開機時能自啓動
docker run -itd --restart always --name lnmp_mysql --net lnmp -p 3306:3306 --mount src=mysql-vol,dst=/var/lib/mysql -e MYSQL_ROOT_PASSWORD=123456 -e MYSQL_DATABASE=wordpress mysql:5.7 --character-set-server=utf8
mysql-vol卷會自動創建。
[root@localhost volumes]# pwd
/var/lib/docker/volumes
[root@localhost volumes]# docker volume ls
DRIVER VOLUME NAME
local mysql-vol
local rancher-agent-state
local rancher-cni
local rancher-cni-driver
[root@localhost volumes]# docker volume inspect mysql-vol
[
{
"CreatedAt": "2019-08-18T11:52:35+08:00",
"Driver": "local",
"Labels": null,
"Mountpoint": "/var/lib/docker/volumes/mysql-vol/_data",
"Name": "mysql-vol",
"Options": null,
"Scope": "local"
}
]
創建一個卷 例如docker volume create nginx-vol
容器創建後就會創建數據庫wordpress
進入mysql容器，docker exec -it lnmp_mysql /bin/bash
進入數據庫 mysql –uroot –p123456
創建普通用戶
grant all on wordpress.* to wordpress@'%' identified by ‘123456’;
flush privileges;
mysql> select user,host from mysql.user;
+---------------+-----------+
| user | host |
+---------------+-----------+
| root | % |
| wordpress | % |
| mysql.session | localhost |
| mysql.sys | localhost |
| root | localhost |
+---------------+-----------+
5 rows in set (0.01 sec)
mysql>
也可以不用進容器操作 docker exec lnmp_mysql bash -c 'exec mysql -uroot -p123456 -e "grant all on wordpress.* to wordpress@'%' identified by ‘123456’;"'
4. 創建web環境（nginx+php），這裏採用的鏡像包含nginx和php-fpm
docker run -itd --restart always --name lnmp_web --net lnmp -p 88:80 --mount type=bind,src=/lnmp/web,dst=/var/www/html richarvey/nginx-php-fpm
在本地創建/lnmp/web目錄，將該目錄掛載到容器，實現數據持久化。
5.Wordpress博客
在wordpress官網https://cn.wordpress.org/下載wordpress解壓到/lnmp/web中
訪問 http://192.168.56.135:88/wordpress，然後就可以進行wordpress的配置及安裝
