阿里云ecs部署freeswitch默认event socket listen port 8021 ipv6问题

阿里云ecs服务器目前还不支持ipv6
freeswitch默认event_socket模块配置
/etc/freeswitch/autoload_configs/event_socket.conf.xml

<configuration name="event_socket.conf" description="Socket Client">
  <settings>
    <param name="nat-map" value="false"/>
    <param name="listen-ip" value="::"/>
    <param name="listen-port" value="8021"/>
    <param name="password" value="ClueCon"/>
    <!--<param name="apply-inbound-acl" value="loopback.auto"/>-->
    <!--<param name="stop-on-bind-error" value="true"/>-->
  </settings>
</configuration>

</settings>

</configuration>

里的<param name=”listen-ip” value=”::”/>是ipv6地址的表现形式，其等同于ipv4的0.0.0.0
这就造成服务启动后，由于无法绑定ipv6地址，也就不能通过fs_cli命令行进行控制台管理了
这就解释了同样的配置在本机一切正常，部署到阿里云上就无法管理

知道原理解决起来就简单了，将listen-ip的value根据实际需要改成127.0.0.1、0.0.0.0或内外网卡的ipv4地址即可

odoo addons xml develop debug auto update

odoo以开发者模式运行的话，能自动检测所有的addons目录的代码变动情况自动进行reload
这个机制对于python代码来说是够用的，但是对csv安全规则、xml数据及视图模版来说还需要更新模块才能使其生效

今天由于逐个测试安全规则条目，不断的手工更新模块不胜其烦，只好深入研究一下

odoo9开始已经将开发者模式依赖的pyinotify替换为watchdog，可能是后者的应用范围更广把，不仅提供python库，还附带shell工具

那就学习下这个叫watchmedo的命令行工具吧

(python)[srj@x1c odoo9]$ watchmedo --help
usage: watchmedo [-h] [--version]
                 
                 {tricks-from,tricks-generate-yaml,log,shell-command,auto-restart}
                 ...

positional arguments:
  {tricks-from,tricks-generate-yaml,log,shell-command,auto-restart}
    tricks-from         Subcommand to execute tricks from a tricks
                        configuration file. :param args: Command line argument
                        options.
    tricks-generate-yaml
                        Subcommand to generate Yaml configuration for tricks
                        named on the command line. :param args: Command line
                        argument options.
    log                 Subcommand to log file system events to the console.
                        :param args: Command line argument options.
    shell-command       Subcommand to execute shell commands in response to
                        file system events. :param args: Command line argument
                        options.
    auto-restart        Subcommand to start a long-running subprocess and
                        restart it on matched events. :param args: Command
                        line argument options.

optional arguments:
  -h, --help            show this help message and exit
  --version             show program's version number and exit

(python)[srj@x1c odoo9]$ watchmedo --help

usage: watchmedo [-h] [--version]

{tricks-from,tricks-generate-yaml,log,shell-command,auto-restart}

...

positional arguments:

{tricks-from,tricks-generate-yaml,log,shell-command,auto-restart}

tricks-from Subcommand to execute tricks from a tricks

configuration file. :param args: Command line argument

options.

tricks-generate-yaml

Subcommand to generate Yaml configuration for tricks

named on the command line. :param args: Command line

argument options.

log Subcommand to log file system events to the console.

auto-restart Subcommand to start a long-running subprocess and

restart it on matched events. :param args: Command

optional arguments:

-h, --help show this help message and exit

--version show program's version number and exit

看到auto-restart参数后真是让人眼前一亮，根据提示继续学习二级参数

(python)[srj@x1c odoo9]$ watchmedo auto-restart -h
usage: watchmedo auto-restart [-h] [-d directory] [-p PATTERNS]
                              [-i IGNORE_PATTERNS] [-D] [-R]
                              [--interval TIMEOUT] [--signal SIGNAL]
                              [--kill-after KILL_AFTER]
                              command [arg [arg ...]]

    Subcommand to start a long-running subprocess and restart it
    on matched events.

    :param args:
        Command line argument options.
    

positional arguments:
  command               Long-running command to run in a subprocess.
  arg                   Command arguments. Note: Use -- before the command
                        arguments, otherwise watchmedo will try to interpret
                        them. (default: -)

optional arguments:
  -h, --help            show this help message and exit
  -d directory, --directory directory
                        Directory to watch. Use another -d or --directory
                        option for each directory. (default: -)
  -p PATTERNS, --pattern PATTERNS, --patterns PATTERNS
                        matches event paths with these patterns (separated by
                        ;). (default: '*')
  -i IGNORE_PATTERNS, --ignore-pattern IGNORE_PATTERNS, --ignore-patterns IGNORE_PATTERNS
                        ignores event paths with these patterns (separated by
                        ;). (default: '')
  -D, --ignore-directories
                        ignores events for directories (default: False)
  -R, --recursive       monitors the directories recursively (default: False)
  --interval TIMEOUT, --timeout TIMEOUT
                        use this as the polling interval/blocking timeout
                        (default: 1.0)
  --signal SIGNAL       stop the subprocess with this signal (default SIGINT)
                        (default: 'SIGINT')
  --kill-after KILL_AFTER
                        when stopping, kill the subprocess after the specified
                        timeout (default 10) (default: 10.0)

(python)[srj@x1c odoo9]$ watchmedo auto-restart -h

usage: watchmedo auto-restart [-h] [-d directory] [-p PATTERNS]

[-i IGNORE_PATTERNS] [-D] [-R]

[--interval TIMEOUT] [--signal SIGNAL]

[--kill-after KILL_AFTER]

command [arg [arg ...]]

Subcommand to start a long-running subprocess and restart it

on matched events.

:param args:

Command line argument options.

positional arguments:

command Long-running command to run in a subprocess.

arg Command arguments. Note: Use -- before the command

arguments, otherwise watchmedo will try to interpret

them. (default: -)

optional arguments:

-h, --help show this help message and exit

-d directory, --directory directory

Directory to watch. Use another -d or --directory

option for each directory. (default: -)

-p PATTERNS, --pattern PATTERNS, --patterns PATTERNS

matches event paths with these patterns (separated by

;). (default: '*')

-i IGNORE_PATTERNS, --ignore-pattern IGNORE_PATTERNS, --ignore-patterns IGNORE_PATTERNS

ignores event paths with these patterns (separated by

;). (default: '')

-D, --ignore-directories

ignores events for directories (default: False)

-R, --recursive monitors the directories recursively (default: False)

--interval TIMEOUT, --timeout TIMEOUT

use this as the polling interval/blocking timeout

(default: 1.0)

--signal SIGNAL stop the subprocess with this signal (default SIGINT)

(default: 'SIGINT')

--kill-after KILL_AFTER

when stopping, kill the subprocess after the specified

timeout (default 10) (default: 10.0)

真是太强大了，本以为还要写点小代码什么的，没想到几个选项就可以灵活组合出一个小型的监控工具

watchmedo auto-restart -R -p="*.py;*.xml;*.csv" -d /home/srj/Git/Odoo/custom_addons/account_simple/ -- ./odoo.py -c c.conf -d test9 -u account_simple

1	watchmedo auto-restart -R -p=".py;.xml;*.csv" -d /home/srj/Git/Odoo/custom_addons/account_simple/ -- ./odoo.py -c c.conf -d test9 -u account_simple

-R是目录递归监控
-p是文件模式匹配，主要是排除前端资源和pyc
-d是指定监控目录
–是watchmedo与odoo各自的命令行参数分割线

至此odoo的模块开发效率又提高了一个层次：）

centos odoo decoder jpeg not available

云服务器上传jpg图片提示IOError错误

  File "/usr/lib64/python2.7/site-packages/PIL/ImageFile.py", line 200, in load
    d = Image._getdecoder(self.mode, d, a, self.decoderconfig)
  File "/usr/lib64/python2.7/site-packages/PIL/Image.py", line 417, in _getdecoder
    raise IOError("decoder %s not available" % decoder_name)
IOError: decoder jpeg not available

File "/usr/lib64/python2.7/site-packages/PIL/ImageFile.py", line 200, in load

d = Image._getdecoder(self.mode, d, a, self.decoderconfig)

File "/usr/lib64/python2.7/site-packages/PIL/Image.py", line 417, in _getdecoder

raise IOError("decoder %s not available" % decoder_name)

IOError: decoder jpeg not available

初步判断是python pil库依赖的底层jpeg lib问题
但是本机正常无法重现，于是检查环境

[srj@x1c ~]$ yum list installed|grep jpeg
libjpeg-turbo.x86_64               1.2.90-5.el7                        @anaconda
libjpeg-turbo-devel.x86_64         1.2.90-5.el7                        @anaconda
openjpeg-libs.x86_64               1.5.1-10.el7                        @anaconda

[srj@x1c ~]$ yum list installed|grep jpeg

libjpeg-turbo.x86_64 1.2.90-5.el7 @anaconda

libjpeg-turbo-devel.x86_64 1.2.90-5.el7 @anaconda

openjpeg-libs.x86_64 1.5.1-10.el7 @anaconda

对比了下发现服务器环境没有libjpeg-turbo-devel.x86_64立马补装一个，重启odoo服务错误依旧，于是继续更新Pillow库

重启odoo服务问题解决
最后回顾了下odoo requirements.txt：
odoo8 Pillow==2.5.1
odoo9 Pillow==2.7.0
其实所谓更新无非是重新安装编译一下Pillow库，没想到直接升级到3.1.0版本，希望没有什么副作用：）
