说明：ansible-palybook批量部署tomcat以及tomcat所需要的jdk环境，以及分发站点文件

1.安装python

yum -y install zlib zlib-devel   openssl openssl-devel #后期安装ansible会依赖所以
wgethttp://www.python.org/ftp/python/2.7.11/Python-2.7.11.tgz
gunzip Python-2.7.11.tgz   #查看解压的结果
tar  xf  Python-2.7.11.tar
cd Python-2.7.11
mkdir  -p  /application/python2.7.11
./configure --prefix=/application/python2.7.11
make
make install
mv /usr/bin/python /usr/bin/python_old
ln  -s  /application/python2.7.11/bin/python2   /usr/bin/python

2.python安装需要解决的问题

错误1

[root@haixiao Python-2.7.11]# yum -y  install lrzsz
/usr/bin/python: error while loading sharedlibraries: libpython2.7.so.1.0: cannot open shared object file: No such file ordirectory
解决办法：
vim /usr/bin/yum
#!/usr/bin/python 改成     /usr/bin/python_old
错误2
[root@haixiao bin]# python  -V
python: error while loading shared libraries:libpython2.7.so.1.0: cannot open shared object file: No such file or directory
解决办法：
echo "/application/python2.7.6/lib">>/etc/ld.so.conf
 ldconfig
 python -V

3.安装pip命令为了安装特定版本的ansible

wget https://bootstrap.pypa.io/get-pip.py
pip命令在python安装的路径下的bin下
/opt/service/python2.7.11/bin
所以：
把python的这个环境变量导进入
export PATH=/opt/service/python2.7.11/bin:$PATH
python  get-pip.py

4.安装ansible

 pip   install     ansible==2.0.2

5.ansible基础的命令就不讲解了，直接在另外一台服务器上安装tomcat

ansible分发机：10.0.0.9 内网Ip：172.16.1.9
ansible被分发机：10.0.0.10 内网IP：172.16.1.10  #在此台机器上安装tomcat

6.在10.0.0.9

1.

[root@centos67 ~]# cd /opt/lansgg/ansible_playbook/
[root@centos67 ansible_playbook]# pwd
/opt/lansgg/ansible_playbook

2.

[root@centos67 ansible_playbook]# tree
