SuSe 10.1下安装supervisord进程管理工具

 1. 安装 python-2.7

cd /usr/src/

wget http://www.python.org/ftp/python/2.7/Python-2.7.tar.bz2

tar jxvf Python-2.7.tar.bz2

cd /usr/src/Python-2.7/

./configure

make

make install

 

做软链接

ln -sf /usr/local/bin/python /usr/bin/

 

显示版本已经是新安装的2.7版本了,但有报错如下:

[[email protected] bin]# python

Python 2.7 (r27:82500, Sep 12 2012, 19:00:00) 

[GCC 4.1.2 20070115 (prerelease) (SUSE Linux)] on linux2

Type "help", "copyright", "credits" or "license" for more information.

Traceback (most recent call last):

  File "/etc/pythonstart", line 7, in <module>

    import readline

ImportError: No module named readline

>>> 

 

2. 安装 readline

装 readline 之前,需要先安装 setuptools

cd /usr/src/

wget http://pypi.python.org/packages/source/s/setuptools/setuptools-0.6c11.tar.gz#md5=7df2a529a074f613b509fb44feefe74e

tar zxvf setuptools-0.6c11.tar.gz

cd setuptools-0.6c11/

python setup.py install

 

出现"

Installed /usr/local/lib/python2.7/site-packages/setuptools-0.6c11-py2.7.egg

Processing dependencies for setuptools==0.6c11

Finished processing dependencies for setuptools==0.6c11

"      表示安装成功

 

然后,安装 readline-devel ,从SuSe系统自带的DVD光盘拷贝对应rpm包.

rpm -ivh readline-devel-5.1-24.13.x86_64.rpm 

rpm -ivh readline-devel-32bit-5.1-24.13.x86_64.rpm 

装完这两个依赖包,就可以开始安装 readline 了

cd /usr/src/

wget ftp://ftp.cwru.edu/pub/bash/readline-5.2.tar.gz

tar zxvf readline-5.2.tar.gz

cd readline-5.2/

CFLAGS="-O3 -fPIC" ./configure

(一定要加"-O3 -fPIC",不然会报错:"libreadline.a: could not read symbols: Bad value")

make CFLAGS=-fPIC

make CFLAGS=-fPIC install

 

3. 安装 python 的 readline 模块

cd /usr/src/

wget http://ipython.scipy.org/dist/readline-2.5.1.tar.gz

tar zxvf readline-2.5.1.tar.gz

cd /usr/src/readline-2.5.1

cp /usr/local/lib/{libreadline.a,libhistory.a} readline/

python setup.py install 

 

出现"

Installed /usr/local/lib/python2.7/site-packages/readline-2.5.1-py2.7-linux-x86_64.egg

Processing dependencies for readline==2.5.1

Finished processing dependencies for readline==2.5.1

"      表示安装成功

 

然后再敲python就不会出现"ImportError: No module named readline"的提示了

 

[[email protected] readline-2.5.1]# python

Python 2.7 (r27:82500, Sep 12 2012, 19:00:00) 

[GCC 4.1.2 20070115 (prerelease) (SUSE Linux)] on linux2

4. 安装 meld3(如果服务器可以从公网下载文件,可直接跳至第5步)

cd /usr/src/

wget http://pypi.python.org/packages/source/m/meld3/meld3-0.6.8.tar.gz#md5=94b1591e518909e239fc17777db3c852

tar zxvf meld3-0.6.8.tar.gz

cd /usr/src/meld3-0.6.8/

python setup.py install

 

5. 安装 Supervisord

cd /usr/src/

tar zxvf supervisor-3.0a10.tar.gz

cd supervisor-3.0a10/

python setup.py install

 

出现

"Installed /usr/local/lib/python2.7/site-packages/supervisor-3.0a10-py2.7.egg

Processing dependencies for supervisor==3.0a10

Searching for meld3==0.6.8

Best match: meld3 0.6.8

Adding meld3 0.6.8 to easy-install.pth file

 

Using /usr/local/lib/python2.7/site-packages

Finished processing dependencies for supervisor==3.0a10", 恭喜,安装完成.

 

6. 配置 Supervisord

生成一个默认的配置文件,

echo_supervisord_conf > /etc/supervisord.conf

下面是我的配置范例:

[[email protected] supervisor-3.0a10]# grep -v "^;" /etc/supervisord.conf

[unix_http_server]

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

chmod=0777                 ; sockef file mode (default 0700)

chown=root:root       ; socket file uid:gid owner

 

## WEB管理 配置

[inet_http_server]         ; inet (TCP) server disabled by default

port=127.0.0.1:8010        ; (ip_address:port specifier, *:port for all iface)

username=admin              ; (default is no username (open server))

password=supper               ; (default is no password (open server))

 

## 全局配置

[supervisord]

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

logfile_maxbytes=50MB       ; (max main logfile bytes b4 rotation;default 50MB)

logfile_backups=10          ; (num of main logfile rotation backups;default 10)

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

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

nodaemon=true              ; (start in foreground if true;default false)

minfds=1024                 ; (min. avail startup file descriptors;default 1024)

minprocs=200                ; (min. avail process descriptors;default 200)

user=root                 ; (default is current user, required if root)

 

[rpcinterface:supervisor]

supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface

 

[supervisorctl]

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

 

## 配置监控对象

[program:monitor_cron]

command=/data/sh/monitor/f4_monitor_cron.sh              ; the program (relative uses PATH, can take args)

autostart=true                ; start at supervisord start (default: true)

startsecs=10                  ; number of secs prog must stay running (def. 1)

redirect_stderr=true          ; redirect proc stderr to stdout (default false)

stdout_logfile=/var/log/supervisord/monitorCron.log        ; stdout log path, NONE for none; default AUTO

 

其中command配置有三种写法,官网上是这样写的:

The command that will be run when this program is started. The command can be either absolute 

1). (e.g. /path/to/programname) or relative (e.g. programname). If it is relative, the supervisord’s

 environment $PATH will be searched for the executable. Programs can accept arguments, 

2). e.g. /path/to/program foo bar. The command line can use double quotes to group arguments with 

spaces in them to pass to the program, e.g. /path/to/program/name -p "foo bar". Note that the 

value of command may include Python string expressions, 

3). e.g. /path/to/programname --port=80%(process_num)02d might expand to /path/to/programname --port=8000 

at runtime. String expressions are evaluated against a dictionary containing the keys group_name, 

host_node_name, process_num, program_name, here (the directory of the supervisord config file), 

and all supervisord’s environment variables prefixed with ENV_. Controlled programs should 

themselves not be daemons, as supervisord assumes it is responsible for daemonizing its subprocesses

 (see Nondaemonizing of Subprocesses).

 

鄙人E文很烂,就不翻译给大家献丑了,大家自由发挥吧,哈哈.

 

 

7. Supervisord 管理

Supervisord安装完成后有两个可用的命令行supervisor和supervisorctl，命令使用解释如下：

 

supervisord，初始启动Supervisord，启动、管理配置中设置的进程。 

supervisorctl stop programxxx，停止某一个进程(programxxx)，programxxx为[program:chatdemon]里配置的值，

这个示例就是"monitor_cron" 

supervisorctl start programxxx，启动某个进程 

supervisorctl restart programxxx，重启某个进程 

supervisorctl stop all，停止全部进程，注：start、restart、stop都不会载入最新的配置文件。 

supervisorctl reload，载入最新的配置文件，并按新的配置启动、管理所有进程。
