安装docker注意事项：
1、替换国内yum源
2、服务器时区和时间保持国内
3、selinux和firewalld关闭


sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-‘EOF‘
{
  "registry-mirrors": ["https://b9pmyelo.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker


docker inspect image nginx

创建一个容器：
1、设置容器名为hello
2、暴露88端口让外部访问
3、传入一个test=123456变量
4、设置开机启动

docker run -d --name hello -e test=123456  -p 88:80 --restart=always  nginx


docker run [OPTIONS] IMAGE [COMMAND] [ARG...]


docker exec -it nginx bash
docker run -it centos bash


nginx -g daemon off;


资源限制：内存、CPU、硬盘、网络


需要持久化的数据：
1、日志，一般用于方便日志采集和故障排查
2、配置文件，比如nginx配置文件
3、业务数据，比如mysql，网站程序
4、临时缓存数据，比如nginx-proxy-cache

-v 数据卷名称或者源目录:容器目标

bind mounts注意点:
1、宿主机文件或者目录必须存在才能成功挂载
2、宿主机文件或者目录覆盖容器中内容


镜像分类：
1、基础镜像，例如centos(yum)、ubuntu(apt)、alpine(apk)
2、环境镜像，例如php、jdk、python
3、项目镜像，打包好的可部署镜像

制作镜像：
1、选择一个符合线上操作系统的基础镜像
2、用基础镜像创建一个容器，手动在容器里面跑一边你要部署的应用
3、确认你启动这个应用的前台运行命令


源码安装：
0. 安装依赖包，例如gcc、make
1、./configure
2、make
3、make install





PHP镜像：
1、PHP环境，可以运行认可php脚本
2、PHP-FPM

; FPM Configuration ;
;;;;;;;;;;;;;;;;;;;;;

; All relative paths in this configuration file are relative to PHP‘s install
; prefix (/usr/local/php). This prefix can be dynamically changed by using the
; ‘-p‘ argument from the command line.

; Include one or more files. If glob(3) exists, it is used to include a bunch of
; files from a glob(3) pattern. This directive can be used everywhere in the
; file.
; Relative path can also be used. They will be prefixed by:
;  - the global prefix if it‘s been set (-p argument)
;  - /usr/local/php otherwise
;include=etc/fpm.d/*.conf

; Pool Definitions ;
;;;;;;;;;;;;;;;;;;;;

; Multiple pools of child processes may be started with different listening

; FPM can handle. Your system will tell you anyway :)

; Start a new pool named ‘www‘.
; the variable $pool can we used in any directive and will be replaced by the
; pool name (‘www‘ here)
[www]

; Per pool prefix
; It only applies on the following directives:
; - ‘access.log‘
; - ‘slowlog‘
; - ‘listen‘ (unixsocket)
; - ‘chroot‘
; - ‘chdir‘

; Choose how the process manager will control the number of child processes.
; Possible Values:
;   static  - a fixed number (pm.max_children) of child processes;

;                                    state (waiting to process). If the number
;                                    of ‘idle‘ processes is less than this
;                                    number then some children will be created.

; Note: This value is mandatory.
pm = dynamic

; The number of child processes to be created when pm is set to ‘static‘ and the
; maximum number of child processes when pm is set to ‘dynamic‘ or ‘ondemand‘.
; This value sets the limit on the number of simultaneous requests that will be
; served. Equivalent to the ApacheMaxClients directive with mpm_prefork.
; Equivalent to the PHP_FCGI_CHILDREN environment variable in the original PHP
; CGI. The below defaults are based on a server without much resources. Don‘t
; forget to tweak pm.* to fit your needs.
; Note: Used when pm is set to ‘static‘, ‘dynamic‘ or ‘ondemand‘
; Note: This value is mandatory.
pm.max_children = 200

; Default Value: 0
pm.max_requests = 51200

; The URI to view the FPM status page. If this value is not set, no URI will be

;   http://www.foo.bar/status?json&full
;   http://www.foo.bar/status?html&full
;   http://www.foo.bar/status?xml&full

;   last request cpu     - the %cpu the last request consumed
;                          it‘s always 0 if the process is not in Idle state
;                          because CPU calculation is done when the request

;  %M: peak of memory allocated by PHP
;      it can accept the following format:
;      - %{bytes}M (default)
;      - %{kilobytes}M
;      - %{kilo}M
;      - %{megabytes}M
;      - %{mega}M
;  %n: pool name
;  %o: output header
;      it must be associated with embraces to specify the name of the header:
;      - %{Content-Type}o
;      - %{X-Powered-By}o
;      - %{Transfert-Encoding}o
;      - ....
;  %p: PID of the child that serviced the request
;  %P: PID of the parent of the child that serviced the request
;  %q: the query string
;  %Q: the ‘?‘ character if query string exists
;  %r: the request URI (without the query string, see %q and %Q)
;  %R: remote IP address
;  %s: status (response code)
;  %t: server time the request was received
;      it can accept a strftime(3) format:
;      %d/%b/%Y:%H:%M:%S %z (default)
;  %T: time the log has been written (the request has finished)
;      it can accept a strftime(3) format:
;      %d/%b/%Y:%H:%M:%S %z (default)
;  %u: remote user
;
; Default: "%R - %u %t \"%m %r\" %s"
;access.format = "%R - %u %t \"%m %r%Q%q\" %s %f %{mili}d %{kilo}M %C%%"

; The log file for slow requests
; Default Value: not set
; Note: slowlog is mandatory if request_slowlog_timeout is set
slowlog = log/$pool.log.slow

; The timeout for serving a single request after which a PHP backtrace will be
; dumped to the ‘slowlog‘ file. A value of ‘0s‘ means ‘off‘.
; Available units: s(econds)(default), m(inutes), h(ours), or d(ays)
; Default Value: 0
request_slowlog_timeout = 10

; The timeout for serving a single request after which the worker process will
; be killed. This option should be used when the ‘max_execution_time‘ ini option
; does not stop script execution for some reason. A value of ‘0‘ means ‘off‘.
; Available units: s(econds)(default), m(inutes), h(ours), or d(ays)
; Default Value: 0
request_terminate_timeout = 600

; Set open file descriptor rlimit.
; Default Value: system defined value
rlimit_files = 10240

; Set max core size rlimit.
; Possible Values: ‘unlimited‘ or an integer greater or equal to 0
; Default Value: system defined value
;rlimit_core = 0

; Chroot to this directory at the start. This value must be defined as an
; absolute path. When this value is not set, chroot is not used.
; Note: you can prefix with ‘$prefix‘ to chroot to the pool prefix or one
; of its subdirectories. If the pool prefix is not set, the global prefix
; will be used instead.
; Note: chrooting is a great security feature and should be used whenever
;       possible. However, all PHP paths will be relative to the chroot
;       (error_log, sessions.save_path, ...).
; Default Value: not set
;chroot =

; Chdir to this directory at the start.
; Note: relative path can be used.
; Default Value: current directory or / when chroot
;chdir = /var/www

; Redirect worker stdout and stderr into main error log. If not set, stdout and
; stderr will be redirected to /dev/null according to FastCGI specs.
; Note: on highloaded environement, this can cause some delay in the page
; process time (several ms).
; Default Value: no
;catch_workers_output = yes

; Clear environment in FPM workers
; Prevents arbitrary environment variables from reaching FPM worker processes
; by clearing the environment in workers before env vars specified in this
; pool configuration are added.
; Setting to "no" will make all environment variables available to PHP code
; via getenv(), $_ENV and $_SERVER.
; Default Value: yes
;clear_env = no

; Limits the extensions of the main script FPM will allow to parse. This can
; prevent configuration mistakes on the web server side. You should only limit
; FPM to .php extensions to prevent malicious users to use other extensions to
; exectute php code.
; Note: set an empty value to allow all extensions.
; Default Value: .php
;security.limit_extensions = .php .php3 .php4 .php5

; Pass environment variables like LD_LIBRARY_PATH. All $VARIABLEs are taken from
; the current environment.
; Default Value: clean env
;env[HOSTNAME] = $HOSTNAME
;env[PATH] = /usr/local/bin:/usr/bin:/bin
;env[TMP] = /tmp
;env[TMPDIR] = /tmp
;env[TEMP] = /tmp

; Additional php.ini defines, specific to this pool of workers. These settings
; overwrite the values previously defined in the php.ini. The directives are the
; same as the PHP SAPI:
;   php_value/php_flag             - you can set classic ini defines which can
;                                    be overwritten from PHP call ‘ini_set‘.
;   php_admin_value/php_admin_flag - these directives won‘t be overwritten by
;                                     PHP call ‘ini_set‘
; For php_*flag, valid values are on, off, 1, 0, true, false, yes or no.

; Defining ‘extension‘ will load the corresponding shared extension from
; extension_dir. Defining ‘disable_functions‘ or ‘disable_classes‘ will not
; overwrite previously defined php.ini values, but will append the new value
; instead.

; Note: path INI options can be relative and will be expanded with the prefix
; (pool, global or /usr/local/php)

; Default Value: nothing is defined by default except the values in php.ini and
;                specified at startup with the -d argument
;php_admin_value[sendmail_path] = /usr/sbin/sendmail -t -i -f www@my.domain.com
;php_flag[display_errors] = off
;php_admin_value[error_log] = /var/log/fpm-php.www.log
;php_admin_flag[log_errors] = on
;php_admin_value[memory_limit] = 32M
