系统预配置

关闭防火墙

[root@localhost ~]# systemctl stop firewalld

关闭防火墙开机启动

[root@localhost ~]# systemctl disable firewalld
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.

关闭强制访问控制安全策略

vi /etc/sysconfig/selinux

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=enforcing
# SELINUXTYPE= can take one of three two values:
#     targeted - Targeted processes are protected,
#     minimum - Modification of targeted policy. Only selected processes are protected.
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted

SELINUX=enforcing改成SELINUX=disabled

reboot使禁用操作生效

查看操作是否生效

[root@localhost ~]# getenforce
Disabled

安装Python3

wget https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tar.xz

解压编译包

tar xf Python-3.7.0.tar.xz

查看文件

[root@localhost ~]# ls
anaconda-ks.cfg  Python-3.7.0  Python-3.7.0.tar.xz
[root@localhost ~]# cd Python-3.7.0

安装OpenSSL依赖，否则使用pip3.7会报找不到SSL模块错误

yum install openssl-devel

设定编译参数，/usr/local为安装位置，--with-ensurepip=install指定安装包管理工具，--enable-shared配置Python匹配系统参数

[root@localhost Python-3.7.0]# ./configure --prefix=/usr/local --with-ensurepip=install --enable-shared LDFLAGS="-Wl,-rpath /usr/local/lib" --with-ssl
checking build system type... x86_64-pc-linux-gnu
checking host system type... x86_64-pc-linux-gnu
checking for python3.7... no
checking for python3... no
checking for python... python
checking for --enable-universalsdk... no
checking for --with-universal-archs... no
checking MACHDEP... checking for --without-gcc... no
checking for --with-icc... no
checking for gcc... no
checking for cc... no
checking for cl.exe... no
configure: error: in `/root/Python-3.7.0':
configure: error: no acceptable C compiler found in $PATH
See `config.log' for more details

报错为找不到C编译器，由于系统为最小化安装，没有自带gcc编译器
安装gcc

yum install gcc

再次编译，编译通过
安装编译文件

 make && make altinstall

日志如下

Traceback (most recent call last):
  File "/root/Python-3.7.0/Lib/runpy.py", line 193, in _run_module_as_main
    "__main__", mod_spec)
  File "/root/Python-3.7.0/Lib/runpy.py", line 85, in _run_code
    exec(code, run_globals)
  File "/root/Python-3.7.0/Lib/ensurepip/__main__.py", line 5, in <module>
    sys.exit(ensurepip._main())
  File "/root/Python-3.7.0/Lib/ensurepip/__init__.py", line 204, in _main
    default_pip=args.default_pip,
  File "/root/Python-3.7.0/Lib/ensurepip/__init__.py", line 117, in _bootstrap
    return _run_pip(args + [p[0] for p in _PROJECTS], additional_paths)
  File "/root/Python-3.7.0/Lib/ensurepip/__init__.py", line 27, in _run_pip
    import pip._internal
zipimport.ZipImportError: can't decompress data; zlib not available

make: *** [altinstall] 错误 1

编译报错，找不到zlib，同理，安装zlib

yum -y install zlib*

另外，此时安装的是3.7版本，3.7版本需要一个新的包libffi-devel否则也会编译报错

yum install libffi-devel -y

安装成功

Python3.7对应的包管理工具pip版本也为3.7，查看其路径

[root@localhost Python-3.7.0]# which pip3.7
/usr/local/bin/pip3.7

设置软链接

ln -s /usr/local/bin/pip3.7 /usr/local/bin/pip

安装virtualenv

安装virtualenv，用于隔离Python环境

pip install virtualenv

安装git工具及其依赖

yum -y install git nss curl

创建ansible账户

useradd ansible

切换用户

[root@localhost Python-3.7.0]# su - ansible
[ansible@localhost ~]$

在ansible用户下创建virtualenv实例，用于集成ansible2.5

virtualenv -p /usr/local/bin/python3.7 .py3-a2.5-env

源码安装git-ansible2.5

cd /home/ansible/.py3-a2.5-env

下载源码

git clone https://github.com/ansible/ansible.git

加载virtualenv环境

[ansible@localhost .py3-a2.5-env]$ source /home/ansible/.py3-a2.5-env/bin/activate
(.py3-a2.5-env) [ansible@localhost .py3-a2.5-env]$

安装ansible依赖

pip install paramiko PyYAML jinja2

分支 stable-2.5 设置为跟踪来自 origin 的远程分支 stable-2.5。
切换到一个新分支 'stable-2.5'
