Docker LNMP 请参考 https://github.com/lanseyujie/docker-lnmp
文中内容仅供在 Deepin Linux amd64 15.7 系统环境下搭建 测试 环境参考，其它版本系统和生产环境请酌情参考。
学习 PHP 的过程是避免不了与开发环境打交道的，之前在 Windows 系统时用的是 phpStudy 集成环境，图形化的界面和高度集成的傻瓜式操作，确实是方便简单了不少，但也因此让我忽视了环境配置。后来转到 Deepin 系统了，使用的也是使用一个集成开发环境 —— XAMPP，这次是在 Linux 环境了，配置环境不能再像 phpStudy 那样点点鼠标就行了，但由于前期在 Windows 上并没有注重这些，开始用的时候确实十分不顺手。又用过一段时间，发现几个 XAMPP 有许多小问题，比如不能编译插件，配置繁琐。中间有想换成 LNMP 的，可是搜索后发现 Linux 上并没有此类集成开发环境，想到服务器是用的一键 LNMP 安装包便想安装一下，但没成想这个一键安装包会卸载 DDE 桌面环境......终于被逼无奈的搭建了适合自己的本地 LNMP 开发环境，本文由此开始......

Installing MariaDB/MySQL system tables in './data' ...
OK
To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system
PLEASE REMEMBER TO SET A PASSWORD FOR THE MariaDB root USER !
To do so, start the server, then issue the following commands:
'./bin/mysqladmin' -u root password 'new-password'
'./bin/mysqladmin' -u root -h lanseyujie password 'new-password'
Alternatively you can run:
'./bin/mysql_secure_installation'
which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.
See the MariaDB Knowledgebase at http://mariadb.com/kb or the
MySQL manual for more instructions.
You can start the MariaDB daemon with:
cd '.' ; ./bin/mysqld_safe --datadir='./data'
You can test the MariaDB daemon with mysql-test-run.pl
cd './mysql-test' ; perl mysql-test-run.pl
Please report any problems at http://mariadb.org/jira
The latest information about MariaDB is available at http://mariadb.org/.

常见问题
内存设置问题
现象
WARNING overcommit_memory is set to 0! Background save may fail under low memory condition. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect.
原因
0 表示内核将检查是否有足够的可用内存供应用进程使用；如果有足够的可用内存，内存申请允许；否则，内存申请失败，并把错误返回给应用进程。
1 表示内核允许分配所有的物理内存，而不管当前的内存状态如何。
2 表示内核允许分配超过所有物理内存和交换空间总和的内存。
解决
# 临时解决 sudo su echo 1 > /proc/sys/vm/overcommit_memory # 永久解决（修改后需要重启生效） sudo su echo \"vm.overcommit_memory=1\" > /etc/sysctl.conf
透明大页问题
现象
WARNING you have Transparent Huge Pages (THP) support enabled in your kernel. This will create latency and memory usage issues with Redis. To fix this issue run the command 'echo never > /sys/kernel/mm/transparent_hugepage/enabled' as root, and add it to your /etc/rc.local in order to retain the setting after a reboot. Redis must be restarted after THP is disabled.
原因
内核使用透明大页可能会导致 redis 延迟和内存使用问题。
解决
# 临时解决 sudo su echo never > /sys/kernel/mm/transparent_hugepage/enabled # 永久解决（修改后需要重启生效） sudo su # 如果存在 /etc/rc.local 文件需要追加这一句 echo \"echo never > /sys/kernel/mm/transparent_hugepage/enabled\" >> /etc/rc.local # 如果不存在 /etc/rc.local 则需要创建添加修改 echo -e '#!/bin/sh \\n echo never > /sys/kernel/mm/transparent_hugepage/enabled' > rc.local
无法退出问题
现象
User requested shutdown...
Saving the final RDB snapshot before exiting.
Failed opening the RDB file dump.rdb (in server root dir /usr/local/redis) for saving: Permission denied
Error trying to save the DB, can't exit.
原因
redis 路径权限不够
解决
sudo chown $USER:$USER -R /usr/local/redis
