docker-ce 搭建的 lamp 开发环境笔记

工作目录: /home/{username}/dockers/lamp

将docker容器的apache的80 映射为本地主机的81

# sudo docker pull mattrayner/lamp
git clone https://github.com/wakasann/docker-lamp.git
cd docker-lamp

# Build the 18.04 image
docker build -t=wakasann/lamp:latest -f ./1804/Dockerfile .

mkdir -p ~/dockers/lamp/{app,mysql}
cd ~/dockers/lamp

# Launch a 18.04 based image
# 容器需手动启动
sudo docker run --name lamptest -p "80:80" -p "3306:3306" -p "443:443" -v ${PWD}/app:/app -v ${PWD}/mysql:/var/lib/mysql  wakasann/lamp:latest

# 容器自启动
sudo docker run --restart=always --name lamptest -p "80:80" -p "3306:3306" -p "443:443" -v ${PWD}/app:/app -v ${PWD}/mysql:/var/lib/mysql  wakasann/lamp:latest

--restart=always 参数的值always 是容器停止之后，会进行重新启动

php 7.3

运行日志:

vagrant@vagrant:~/dockers/lamp$ sudo docker run --name lamptest -p "81:80" -p "3306:3306" -v ${PWD}/app:/app -v ${PWD}/mysql:/var/lib/mysql  mattrayner/lamp:latest-1804

You can now connect to this MySQL Server with YDvRU5FwZf2n

    mysql -uadmin -pYDvRU5FwZf2n -h<host> -P<port>

Please remember to change the above password as soon as possible!
MySQL user 'root' has no password but only allows local connections

enjoy!

上面会输出 mysql admin用户的密码

fix mcrypt.so at php 7.3

进入docker lamp 容器中

sudo docker exec -ti lamptest /bin/bash

查看 php版本

root@43cdda3f409c:/usr/lib/php/20180731# php -v
PHP Warning:  PHP Startup: Unable to load dynamic library 'mcrypt.so' (tried: /usr/lib/php/20180731/mcrypt.so (/usr/lib/php/20180731/mcrypt.so: cannot open shared object file: No such file or directory), /usr/lib/php/20180731/mcrypt.so.so (/usr/lib/php/20180731/mcrypt.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

修复 Unable to load dynamic library 'mcrypt.so' 在 php 7.3

# 验证 php和 pecl的版本
php -v
pecl version

安装 mcrypt 扩展

Mcrypt PECL 扩展

apt-get -y install gcc make autoconf libc-dev pkg-config
apt-get -y install libmcrypt-dev
apt-get install php7.3-dev # 让phpize命令可执行，如果出现phpize: not found需执行这句
pecl install mcrypt

当你看到显示的提示:

libmcrypt prefix? [autodetect] : 

按 [Enter] 回车键 来自动选择。

当通过 pecl 安装成功之后，你应该将mcrypt.so 扩展添加到 php.ini

输出的内容像:

...
Build process completed successfully
Installing '/usr/lib/php/20180731/mcrypt.so'
install ok: channel://pecl.php.net/mcrypt-1.0.3
configuration option "php_ini" is not set to php.ini location
You should add "extension=mcrypt.so" to php.ini

从上面的输出获取到安装的路径，并将其加入到 cli和apache php.ini 配置文件中(因Docker lamp已经执行了这一步，只做备忘)

sudo bash -c "echo extension=/usr/lib/php/20180731/mcrypt.so > /etc/php/7.3/cli/conf.d/mcrypt.ini"
sudo bash -c "echo extension=/usr/lib/php/20180731/mcrypt.so > /etc/php/7.3/apache2/conf.d/mcrypt.ini"

重启apache

service apache2 restart

验证 mcrypt 已经按照成功

$ php -i | grep "mcrypt"
/etc/php/7.3/cli/conf.d/20-mcrypt.ini,
Registered Stream Filters => zlib.*, string.rot13, string.toupper, string.tolower, string.strip_tags, convert.*, consumed, dechunk, convert.iconv.*, mcrypt.*, mdecrypt.*
mcrypt
mcrypt support => enabled
mcrypt_filter support => enabled
mcrypt.algorithms_dir => no value => no value
mcrypt.modes_dir => no value => no value

---

1. 修改myql sql_mode

#Form lamp docker
vim /etc/mysql/my.cnf
vim /etc/my.cnf

都在文件末尾添加以下内容:

[mysqld]
sql_mode=ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
#max_allowed_packet=100M

重启docker lamp容器之后,在 phpmyadmin 中

#phpmyadmin run sql
show variables like 'sql_mode';

临时设置 sql_mode

#phpmyadmin run sql
set global sql_mode='ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION';

2. 修正 apache2 默认列出 Indexs

# Form docker
vim /etc/apache2/sites-available/000-default.conf

将 <Directory /var/www/html> 的Options Indexes FollowSymLinks MultiViews 改为 Options FollowSymLinks MultiViews（移除 Indexes）

按ESC键，输入:wq保存文件修改

# Form docker,restart apache2
service apache2 restart

rsync note

通过ssh的方式，将远程的文件同步到当前服务器的一个文件夹下

将 远程的 /home/vagrant/sh/ 文件放入到本机的/home/vagrant/syncfrom155文件夹中

rsync -v -r -e ssh vagrant@192.168.1.155:/home/vagrant/sh/* /home/vagrant/syncfrom155

补充 docker容器自启动

$ docker run --help
...
--restart string                 Restart policy to apply when a container exits (default "no")
...

显示 docker run 命令的帮助信息

因上面docker 命令启动 lamp 容器时，没有加--restart=always 参数

docker run --restart=always

如果已创建容器并已启动，可通过下面的命令进行添加:

docker update --restart=always <CONTAINER ID>

如果想容器在 docker stop 之后，不想让容器自启动，尝试通过

docker update --restart=no <CONTAINER ID>
