centos操作---搭建环境 安装python

1.安装python3.6.2

安装依赖

yum -y groupinstall "Development tools"
yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel

下载python 解压 软链

wget https://www.python.org/ftp/python/3.6.2/Python-3.6.2.tar.xz

创建安装目录

mkdir /usr/local/python3

安装 gcc 由于 Python 3.6.2 的编译需要编译环境，故需安装 gcc。

yum -y install gcc

解压 Python 3.6.2 并安装在 /usr/local/python3 目录下。

tar -xvJf  Python-3.6.2.tar.xz
cd Python-3.6.2
./configure --prefix=/usr/local/python3
make && make install

创建软链

ln -s /usr/local/python3/bin/python3 /usr/bin/python3
ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3

2.安装MySQL

3.systemctl: command not found

 systemctl status vsftpd.service
-bash: systemctl: command not found

centos6 没有使用 systemd，所以没有 systemctl 命令。

可以使用 service 命令，service vsftpd status
