# graphical.target: analogous to runlevel 5systemctl set-default multi-user.target
操作&＃xff1a;
[root&＃64;centos7 ~]# cat /etc/inittab
# inittab is no longer used when using systemd.
#
# ADDING CONFIGURATION HERE WILL HAVE NO EFFECT ON YOUR SYSTEM.
#
# Ctrl-Alt-Delete is handled by /usr/lib/systemd/system/ctrl-alt-del.target
#
# systemd uses &＃39;targets&＃39; instead of runlevels. By default, there are two main targets:
#
# multi-user.target: analogous to runlevel 3
# graphical.target: analogous to runlevel 5
#
# To view current default target, run:
# systemctl get-default
#
# To set a default target, run:
# systemctl set-default TARGET.target
#
[root&＃64;centos7 ~]# systemctl get-default
multi-user.target
[root&＃64;centos7 ~]# systemctl set-default multi-user.target
Removed symlink /etc/systemd/system/default.target.
Created symlink from /etc/systemd/system/default.target to /usr/lib/systemd/system/multi-user.target.
管理服务
systemctl&＃xff1a;融合service和chkconfig的功能于一体&＃xff0c;兼容sysV和LSB得启动脚本&＃xff0c;而且能够在进程启动过程中更有效地引导加载服务。
获取云主机外网IP地址
echo "&＃96;curl -s myip.ipip.net | awk -F " " &＃39;{print $2}&＃39;|awk -F"&＃xff1a;" &＃39;{print $2}&＃39;&＃96;_&＃96;hostname&＃96;" > /etc/hostname
设置开机启动
针对svn&＃xff0c;nginx每次重启后均要手工启动&＃xff0c;好麻烦&＃xff0c;所以考虑将其做成开机启动&＃xff0c;做成服务好麻烦&＃xff0c;考虑像windows 一样&＃xff0c;放在某个启动项中完成。
打开启动文件后&＃xff0c;发现里面文件内容如下&＃xff1a;
#!/bin/bash
# THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES
#
# It is highly advisable to create own systemd services or udev rules
# to run scripts during boot instead of using this file.
#
# In contrast to previous versions due to parallel execution during boot
# this script will NOT be run after all other services.
#
# Please note that you must run &＃39;chmod &＃43;x /etc/rc.d/rc.local&＃39; to ensure
# that this script will be executed during boot.
意思很简单&＃xff0c;需要将此文件权限改为可执行的&＃xff0c;这也是为何开机后此文件不能执行的原因
操作步骤&＃xff1a;
a. 添加可执行权限&＃xff1a;
# chmod &＃43;x /etc/rc.d/rc.localb. 打开文件rc.local&＃xff1a;
# vim /etc/rc.d/rc.localc. 在文件rc.local末添加开机应启动的脚本&＃xff1a;
svnserve -d -r /var/svn
/usr/nginx/sbin/nginxd. 重启机器&＃xff0c;验证svn和nginx已经启动成功
# reboot
