定义一个方式
远程启动tomcat，但是报错
报错如下
| Neither the JAVA_HOME nor the JRE_HOME environment variable is defined
At least one of these environment variable is needed to run this program |
怎么办 ？
问里群里大神，需要在执行
shell的时候加入JAVA_HOME路径。
于是获取JAVA_HOME路径，于是就有了上面的代码，但是还是不行，因为这样还是获取不到java路径
没办法，问题困扰很久，改用其他模块
# coding:utf-8
from fabric.api import run, env, hosts
def start_up_fabric(host, user, pwd, path):
"""启动服务"""
host_ = host + ':22'
env.hosts = [host_]
env.user = user
env.password = pwd
# utput = run('echo $JAVA_HOME')
# print output
command = 'sh {0}bin/startup.sh'.format(path)
run(command)
最开始使用的是env.hosts = [host,]
依然有问题, 因为其他方法调用这个方法的时候 仍然需要手动输入host
继续查 继续修改 于是问题终于搞定
下面的代码 可以
远程执行shell 启动tomcat不需要指定java/jre路径 而且不会再需要手动输入host
# coding:utf-8
from fabric.api import run, env, hosts
def start_up_fabric(host, user, pwd, path):
"""启动服务"""
host_ = host + ':22'
env.host_string = host_
env.user = user
env.password = pwd
# utput = run('echo $JAVA_HOME')
# print output
command = 'sh {0}bin/startup.sh'.format(path)
run(command,pty=False)
