Ubuntu 16.04开机自启Nginx简单脚本
本文要记述的是最简单的Ubuntu下开机自启 nginx的脚本
这里将nginx装在了/usr/local/nginx目录下,nginx本身没有注册成服务,所以直接使用服务开机自启是不行的,除非自己写nginx.service脚本,这不在本文范畴内。
创建脚本文件
$ sudo vim /etc/init.d/nginx.sh
脚本内容,注意替换root密码、nginx执行文件目录和配置文件目录
#!/bin/bash
#auto run nginx when system startup
sudo -S /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf << EOF
root密码
EOF
exit 0
指定开机自启,最后可以添加优先级,比如,90
$ sudo update-rc.d nginx.sh defaults
此时重启就可以发现nginx已经开机自启了。
如果你在写完启动脚本的后,手动运行该脚本以确定是否可行的话,你会得到一个错误
insserv: warning: script 'nginx.sh' missing LSB tags and overrides
,这种错误不会影响脚本的启动,只是提示脚本写的不规范,没有在脚本中发现以### BEGIN INIT INFO
开头,以### END INIT INFO
结尾的标签,因为没有影响,这里就没有写,可以参考下边的脚本去去除这个错误:
#!/bin/sh
# kFreeBSD do not accept scripts as interpreters, using #!/bin/sh and sourcing.
if [ true != "$INIT_D_SCRIPT_SOURCED" ] ; then
set "$0" "$@"; INIT_D_SCRIPT_SOURCED=true . /lib/init/init-d-script
fi
### BEGIN INIT INFO
# Provides: skeleton
# Required-Start: $remote_fs $syslog
# Required-Stop: $remote_fs $syslog
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
