一：创建用户，修改密码，增加sudo权限。

useradd dolphinscheduler
#输入密码
passwd dolphinscheduler
# 配置 sudo 免密
sed -i '$adolphinscheduler  ALL=(ALL)  NOPASSWD: NOPASSWD: ALL' /etc/sudoers
sed -i 's/Defaults    requirett/#Defaults    requirett/g' /etc/sudoers

二：修改配置

# 在root用户下执行
root@hadoop101:/opt$ vim /etc/passwd

root@hadoop100:~#  sudo mkdir /home/dolphinscheduler
root@hadoop100:~# sudo chown dolphinscheduler:dolphinscheduler /home/dolphinscheduler

root@hadoop100:~# su dolphinscheduler
dolphinscheduler@hadoop100:/root$ cp /etc/skel/.bashrc ~/
dolphinscheduler@hadoop100:/root$ vi ~/.profile

将以下内容填写到 ~/.profile

# if running bash
if [ -n "$BASH_VERSION" ]; then
    # include .bashrc if it exists
    if [ -f "$HOME/.bashrc" ]; then
        . "$HOME/.bashrc"
    fi
fi

# set PATH so it includes user's private bin if it exists
if [ -d "$HOME/bin" ] ; then
    PATH="$HOME/bin:$PATH"
fi

# set PATH so it includes user's private bin if it exists
if [ -d "$HOME/.local/bin" ] ; then
    PATH="$HOME/.local/bin:$PATH"
fi

dolphinscheduler@hadoop100:/root$ source ~/.profile
退出普通用户 Ctrl+D
root@hadoop100:~# sudo bash
root@hadoop100:~# chmod 775 .
