0x01 纪录Linux用户操作日志

root下将如下语句追加到 # vi /etc/profile文件中，然后 # source /etc/profile使配置生效。

USER_IP=`who am i 2>/dev/null| awk '{print $NF}'|sed -e 's/[()]//g'`
USER=`whoami`
export PROMPT_COMMAND="history -a"
if [ "$USER_IP" = "" ]; then
    USER_IP=$HOSTNAME
fi
if [ ! -d /tmp/.bash_history/$USER/ ]; then
    mkdir -p /tmp/.bash_history/$USER/
fi
export HISTSIZE=4096
export HISTTIMEFORMAT="%Y-%m-%d_%H:%M:%s "
DT=`date +%Y%m%d`
export HISTFILE="/tmp/.bash_history/$USER/${DT}_$USER_IP.log"
chattr +a /tmp/.bash_history/$USER/$DT_$USER_IP.log 2>/dev/null

[Nginx]
name=Nginx repo
baseurl=http://Nginx.org/packages/mainline/OS/OSRELEASE/$basearch/
gpgcheck=0
enabled=1

“OS”替换成rhel 或者 centos；
“OSRELEASE”替换成对应的版本号5代表5.x,6代表 6.x,7代表7.x系列的操作系统
“/mainline” 代表获取最新的主线版本(不是稳定版本)。如果获取最新的稳定版本则将/mainline直接删除掉即可。

# 方法二：直接rpm安装官方提供的Nginx源
# rpm -ivh https://raw.githubusercontent.com/jsbd/learn/master/Nginx/Nginx-release-centos-6-0.el6.ngx.noarch.rpm
# yum -y install Nginx

# Nginx配置文件
# cat /etc/Nginx/Nginx.conf

# 设置开机启动Nginx
# chkconfig Nginx on
# service Nginx start
