Ansible2.5 + Python3.6 安装部署

安装 python3.6.5 和 virtualenv 工具

安装python3.6.5

[root@ansible ~]# wget http://www.python.org/ftp/python/3.6.5/Python-3.6.5.tar.xz
[root@ansible ~]# tar -xf Python-3.6.5.tar.xz -C /usr/local/src/
[root@ansible ~]# cd /usr/local/src/Python-3.6.5/
[root@ansible ~]# cd /usr/local/src/Python-3.6.5/
[root@ansible Python-3.6.5]# ./configure --prefix=/usr/local/ --with-ensurepip=install --enable-shared LDFLAGS="-Wl,-rpath /usr/local/lib"

#这里可能会报错
configure: error: in `/usr/local/src/Python-3.6.5':
configure: error: no acceptable C compiler found in $PATH
See `config.log' for more details
# 根据报错信息，需要安装GCC套件
[root@ansible Python-3.6.5]# yum install -y gcc
# 然后再次执行编译操作，完事执行安装
[root@ansible Python-3.6.5]# make && make altinstall
# 然而又报错了
....
    import pip
zipimport.ZipImportError: can't decompress data; zlib not available
make: *** [altinstall] Error 1
# 提示很明显了直接执行
[root@ansible Python-3.6.5]# yum install zlib*
# 然后再次运行安装命令即可
[root@ansible Python-3.6.5]# make && make altinstall
# 当看到
.....
Collecting setuptools
Collecting pip

Successfully installed pip-9.0.3 setuptools-39.0.1
# 表明安装成功

安装 virtualenv

[root@ansible bin]# pwd
/usr/local/bin
[root@ansible bin]# ./pip --trusted-host pypi.python.org install virtualenv
pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.

  Could not find a version that satisfies the requirement virtualenv (from versions: )
No matching distribution found for virtualenv

# 根据第一行报错提示
pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available

# 需要安装 openssl 相关软件包
[root@ansible bin]# yum install -y openssl*

# 除此之外，卸载掉 python2.7 安装的 pip 防止干扰
[root@ansible bin]# python -m pip uninstall pip
Uninstalling pip-18.1:
  Would remove:
    /usr/bin/pip
    /usr/bin/pip2
    /usr/bin/pip2.7
    /usr/lib/python2.7/site-packages/pip-18.1.dist-info/*
    /usr/lib/python2.7/site-packages/pip/*
Proceed (y/n)? y
  Successfully uninstalled pip-18.1

# 然后回到解压包里，重新运行编译安装过程
[root@ansible Python-3.6.5]# ./configure --prefix=/usr/local/ --with-ensurepip=install --enable-shared LDFLAGS="-Wl,-rpath /usr/local/lib"
[root@ansible Python-3.6.5]# make && make altinstall

# 安装成功

创建 ansible 账户并安装 python3.6.5 版本 virtualenv 实例

[root@ansible ~]# useradd deploy && su - deploy
[deploy@ansible ~]$ virtualenv -p /usr/local/bin/python3.6 .py3-a2.5-env
Already using interpreter /usr/local/bin/python3.6

Git 源码安装 ansible2.5

# 首先使用root账户确保git nss curl命令已经安装
[root@ansible ~]# yum install -y git nss curl
# 然后切到deploy用户，进入之前创建的.py3-a2.5-env目录下
[deploy@ansible ~]$ cd /home/deploy/.py3-a2.5-env/
[deploy@ansible .py3-a2.5-env]$ git clone https://github.com/ansible/ansible.git
