docker安装nginx、php、mysql(实际操作)
安装docker环境
yum install -y yum-utils device-mapper-persistent-data lvm2
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
yum makecache fast
yum -y install docker-ce
systemctl start docker
安装nginx:latest
docker pull nginx
docker run --name nginx --restart=always -d -p 80:80 nginx
mkdir -p images webps jsons videos www
cd /usr/local
mkdir -p nginx/{conf,log,html}
cd nginx/conf
mkdir cert
docker cp nginx:/etc/nginx/nginx.conf /usr/local/nginx/conf/nginx.conf
docker cp nginx:/etc/nginx/conf.d /usr/local/nginx/conf/conf.d
docker cp nginx:/usr/share/nginx/html /usr/local/nginx
docker cp nginx:/var/log/nginx /usr/local/nginx/log
cd conf/conf.d
vim default.conf
在default.conf中插入如下代码，进行地址映射
location /files/ {
alias /root/;
}
docker stop nginx
docker rm nginx
docker run --name nginx --restart=always -p 80:80 -p 443:443 -v /usr/local/nginx/conf/nginx.conf:/etc/nginx/nginx.conf -v /usr/local/nginx/conf/conf.d/default.conf:/etc/nginx/conf.d/default.conf -v /usr/local/nginx/log:/var/log/nginx -v /usr/local/nginx/html:/usr/share/nginx/html -v /usr/local/nginx/conf/cert:/etc/nginx/cert -v /achong:/root -d nginx
上传文件测试成功http://XXX.XXX.XXX.XXX/files/test.txt
压缩解压zip
yum install zip && yum install unzip
下载并上传证书到cert文件夹中
vim default.conf
配置https，实现https访问
server {
listen 443 ssl;
server_name www.XXX.com;
ssl_certificate cert/xxxxxxx_www.XXX.com.pem;
ssl_certificate_key cert/xxxxxxx_www.XXXX.com.key;
ssl_session_cache shared:SSL:1m;
ssl_session_timeout 5m;
ssl_ciphers HIGH:!aNULL:!MD5;
ssl_protocols TLSv1.1 TLSv1.2;
ssl_prefer_server_ciphers on;
location / {
root /usr/share/nginx/html;
index index.html index.htm;
}
location /files/ {
alias /root/;
}
}
重启nginx服务
docker restart nginx
将IP地址换成域名，访问成功https://XXX.com/files/jsons/minyue.json
MySql-8.0.30安装
docker pull mysql:8.0.30
cd /usr/local
mkdir -p mysql/{conf,data}
docker run --name mysql --restart=always -d -p 3306:3306 -v /usr/local/mysql/conf:/etc/mysql/conf.d -v /usr/local/mysql/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=XXXXXXXX mysql:8.0.30
PHP:7.4-fpm安装
docker pull php:7.4-fpm
docker run --name myphp -v /achong/www:/www --privileged=true -d --link mysql php:7.4-fpm
cd nginx/conf/conf.d
vim default.conf
在default.conf中插入如下代码，进行地址映射
location ~ \.php$ {
#root html;
fastcgi_pass php:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /www/$fastcgi_script_name;
include fastcgi_params;
}
重新启动nginx
docker run --name nginx --restart=always -p 80:80 -p 443:443 -v /usr/local/nginx/conf/nginx.conf:/etc/nginx/nginx.conf -v /usr/local/nginx/conf/conf.d/default.conf:/etc/nginx/conf.d/default.conf -v /usr/local/nginx/log:/var/log/nginx -v /usr/local/nginx/html:/usr/share/nginx/html -v /usr/local/nginx/conf/cert:/etc/nginx/cert -v /achong:/root --link myphp:php -d nginx
–link myphp:php链接php
如果只使用PDO进行数据库操作可以不进行下面三框代码(不过我也没试过)
// 进入php容器
// 安装扩展
docker exec -it myphp bash
cd /usr/local/bin
./docker-php-ext-install pdo_mysql
./docker-php-ext-install mysqli
cd /usr/local/etc/php
cp php.ini-development php.ini
// 无vim工具
// 从容其中复制php.ini出来
docker cp myphp:/usr/local/etc/php/php.ini /achong/
// 修改（去掉前面的;）
extension=mysqli
extension=pdo_mysql
// 复制回容器
docker cp /achong/php.ini myphp:/usr/local/etc/php/php.ini
// 退出容器，重启php,nginx服务
exit
docker restart myphp
在/achong/www/下创建文件hello.php
echo phpinfo();
?>
测试http://XXX.XXX.XXX.XXX/hello.php成功
PHP连接MySql数据库
创建下面两个php
mysqli.php内容
$conn = mysqli_connect("XXX.XXX.XXX.XXX", "root", "password", "dbname");
if (!$conn) {
die("连接失败: " . mysqli_connect_error());
}
$sql = "SELECT * FROM user_openid";
$result = mysqli_query($conn, $sql);
$data = array();
while ($row = mysqli_fetch_assoc($result)) {
$data[] = $row;
}
$json = json_encode($data);
header('Content-Type: application/json');
echo $json;
mysqli_close($conn);
?>
pdo.php内容
$servername = "XXX.XXX.XXX.XXX";
$username = "root";
$password = "password";
$dbname = "dbname";
try {
$conn = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password);
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$sql = 'SELECT * FROM user_openid;';
$stmt = $conn->query($sql);
$res = $stmt->fetchAll(PDO::FETCH_ASSOC);
header('Content-Type: application/json');
echo json_encode($res);
} catch(PDOException $e) {
echo "连接失败: " . $e->getMessage();
}
?>
测试之前创建记得数据库测试数据
测试方式同上hello.php
结果显示，两种情况下都可以运行
查询错误时有看到两者的区别
1、PDO支持多种数据库
2、MYSQLI仅支持MySql数据库
