alpine编译安装tengine，并使用supervisor启动

Alpine是一个小型的linux系统，官方docker镜像只有不到5MB，非常适合作为容器镜像。

Alpine Linux is a security-oriented, lightweight Linux distribution based on musl libc and Busybox.

A minimal Docker image based on Alpine Linux with a complete package index and only 5 MB in size!

为了更好地了解alpine，我在虚拟机上安装了一个本地alpine。

上官网下载一个标准STANDARD镜像。创建一个虚拟机，我用的 VMWare Fusion，挂载好下载的iso镜像。

然后启动就可以了，不过这时信息没有存盘，需要使用安装脚本安装系统到磁盘。安装过程其实很简单，初次使用，最重要的是要知道有这个安装脚本。

安装脚本叫做 setup-alpine，其实仔细看的话，系统每次启动和登陆的时候都会有提示。

安装系统细节就不说了，如果有疑问可查官方文档。安装完成后，需要重启系统。重启之后，就是从磁盘启动的了。

下面具体说说如何使用：

1、配置安装源。

# vim /etc/apk/repositories

https://mirrors.ustc.edu.cn/alpine/edge/main

https://mirrors.ustc.edu.cn/alpine/edge/community

https://mirrors.ustc.edu.cn/alpine/edge/testing

2、安装ssh服务。Alpine使用的包管理工具叫 apk。服务管理系统叫 OpenRC。

# apk update

# apk add openssh

# rc-service sshd start

# rc-update add sshd

3、修改sshd配置文件，允许root登录。

# vim /etc/ssh/sshd_config

PermitRootLogin yes

# service sshd restart

这时就可以使用终端远程登陆了。

4、安装用户管理工具，修改root用户的shell为bash，默认使用的是ash。

# apk add shadow

# usermod -s /bin/bash root

5、安装常用工具。

# apk add vim bash bash-completion

6、设置常用别名。

# vim /etc/profile

export LS_OPTIONS='--color=auto'

alias ls='ls $LS_OPTIONS'

alias ll='ls $LS_OPTIONS -l'

alias l='ls $LS_OPTIONS -lA'

7、其实在testing源里面，已经有现成的tengine安装包了。不过这里我会测试手动编译，不会直接使用安装包。

# apk policy tengine

tengine policy:

  2.1.0-r4:

    https://mirrors.ustc.edu.cn/alpine/edge/testing

8、如何查看安装包包含哪些文件。有两种方法，不过都只能查看已经安装的包。

# apk manifest tengine | awk '{print $2}'

10、编译安装tengine。这里我加了ldap模块。

# apk add libressl-dev openldap-dev zlib-dev pcre-dev

# mkdir /usr/local/src

# cd /usr/local/src

# git clone https://github.com/kvspb/nginx-auth-ldap.git

# wget http://tengine.taobao.org/download/tengine-2.2.0.tar.gz

# tar xvf tengine-2.2.0.tar.gz

# cd tengine-2.2.0/

# ./configure --prefix=/usr/local/nginx --with-http_reqstat_module=shared --add-module=../nginx-auth-ldap

# make -j 2

# make install

# make dso_install

11、安装supervisor。

# apk add supervisor

修改supervisor的配置文件。

# vim /etc/supervisord.conf

[unix_http_server]

file=/run/supervisord.sock   ; (the path to the socket file)

[supervisord]

logfile=/var/log/supervisord.log ; (main log file;default $CWD/supervisord.log)

loglevel=info                ; (log level;default info; others: debug,warn,trace)

pidfile=/run/supervisord.pid ; (supervisord pidfile;default supervisord.pid)

childlogdir=/var/log/supervisor ; ('AUTO' child log dir, default $TEMP)

environment=LC_ALL=en_US.UTF-8,LANG=en_US.UTF-8,LANGUAGE=en_US.UTF-8

[rpcinterface:supervisor]

supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface

[supervisorctl]

serverurl=unix:///run/supervisord.sock ; use a unix:// URL  for a unix socket

[program:nginx-app]

command = /usr/local/nginx/sbin/nginx

这里需要手动创建日志目录，不然supervisord无法启动。算是一个坑。

# mkdir /var/log/supervisor

# service start supervisord

# supervisorctl

nginx-app                        RUNNING   pid 33479, uptime 0:00:02
