docker安装
略
下载镜像
- nginx:最新版
- php-fpm:根据自己需求而定
- mysql:根据自己需求定
以下是我搭建LNMP使用的镜像版本
root@VM-12-16-ubuntu:/docker/lnmp/php/etc# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE

nginx latest 89da1fb6dcb9 2 weeks ago 187MB
创建路径
# 创建相关目录
mkdir -p /docker/lnmp/php
mkdir -p /docker/lnmp/nginx/conf.d

安装mycli
因为docker安装mysql,服务上没有安装mysql客户端,查询不方便,推荐使用mycli,还带命令提示,还可以
apt install mycli -y
#或
yum install mycli -y
特殊要求
- 如果需要自己修改php.ini,请先运行php-fpm镜像,将配置文件拷贝到服务器上,修改后将文件挂到容器
# 临时启动一个php-fpm
docker run --name myphp -d bitnami/php-fpm:8.1.22
# 将配置文件拷贝到自己服务器上
docker cp myphp:/opt/bitnami/php/etc/ /docker/lnmp/php/etc/
# 删除临时php-fpm容器
docker rm -f myphp
测试
测试nginx是否正常
在根目录下创建index.html
<h1>hello,docker!</>
测试nginx是否能正确解析php文件
在根目录下创建index.php
<?php
phpinfo();
测试mysql
注意:如果你用的云服务器,$servername不要设置成公网地址,否则测试连接不成功,最好设置成你的服务器的私有地址
<?php
//$servername = "mysql" 因为我的compose.yml中mysql服务的名字是“mysql”,如果你也和我一样,可以这样写,不是的话,保持和compose.yml文件中mysql服务名一致
$servername = "mysql";
$username = "root";
$password = "mysql123";
$db_name = 'mysql';
$conn = new mysqli($servername, $username, $password, $db_name);
// 检测连接
if ($conn->connect_error) {die("连接失败: " . $conn->connect_error);
}
echo "连接成功";
php连接mysql8报错处理
# 创建mysql.cnf
touch /docker/lnmp/mysql/conf.d/mysql.cnf
# 修改密码验证插件
cat > /docker/lnmp/mysql/conf.d/mysql.cnf <<EOF
[mysqld]
default-authentication-plugin=mysql_native_password

# 重启mysql镜像
docker-compose -f /docker/lnmp/compose.yml restart mysql
# 登录用root登录mysql
mycli -uroot
# 没有库的可以创建一个,有库跳过这一步
create database blog;
#没有用户的的创建用户,有则跳过
CREATE USER ‘blog‘@‘%‘ IDENTIFIED WITH mysql_native_password BY 'Mysql@2023_!';
#用户授权,有用户的跳过
grant all privileges on blog.* to 'blog'@'%';
#修改密码
ALTER USER ‘native‘@‘localhost‘ IDENTIFIED WITH mysql_native_password BY ‘new_password‘;
# 刷新
flush privileges;
