自启动配置实践
概述

ubuntu下可以通过sysv-rc-conf进行自启动配置
安装sysv-rc-conf

sudo apt-get update
sudo apt-get install sysv-rc-conf


配置fastdfs自启动

sudo ln -s /lib/lsb/init-functions /etc/init.d/functions
sudo sysv-rc-conf
启动图形化配置界面
将2,3,4,5启动级别的fdfs_trackerd,fdfs_storaged都选中
sudo sysv-rc-conf fdfs_trackerd on
sudo sysv-rc-conf fdfs_storaged on


配置nginx自启动
配置libfdfsclient.so库

ln -n /usr/lib64/libfdfsclient.so /usr/lib/libfdfsclient.so
自启动脚本

cd /etc/init.d/
vi nginx
