CentOS7-设置开机自启动-Javalx-Blog

前言

CentOS7开机启动自定义脚本大致分为以下几种方式：

通过CentOS7的rc-local服务启动
使用CentOS7 systemctl 添加系统服务自启动
通过Linux下的chkconfig添加系统启动脚本

systemd自定义服务自启动

Nginx自启动

配置服务文件

在/lib/systemd/system下创建并编辑nginx.service

[root@localhost ~]# cd /lib/systemd/system
[root@localhost ~]# touch nginx.service
[root@localhost ~]# vim nginx.service

[Unit]
#描述服务
Description=nginx
#描述服务在指定服务周后启动
After=network.target
 
#服务运行参数的设置，注意【Service】的启动、重启、停止命令都要用绝对路径
[Service]
#后台运行的形式
Type=forking
#服务具体运行的命令
ExecStart=/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
#重启命令
ExecReload=/usr/local/nginx/sbin/nginx -s reload
#停止命令
ExecStop=/usr/local/nginx/sbin/nginx -s quit
#表示给服务分配独立的临时空间
PrivateTmp=true
 
#运行级别下服务安装的相关设置，可设置为多用户，即系统运行级别为3
[Install]
WantedBy=multi-user.target

重新加载服务配置文件

[root@localhost ~]# systemctl daemon-reload

测试服务配置

[root@localhost ~]# systemctl start nginx.service
[root@localhost ~]# systemctl restart nginx.service
[root@localhost ~]# systemctl stop nginx.service

加入自启动

[root@localhost ~]# systemctl enable nginx.service

Redis自启动

配置服务文件

在/lib/systemd/system下创建并编辑redis.service

[root@localhost ~]# cd /lib/systemd/system
[root@localhost ~]# touch redis.service
[root@localhost ~]# vim redis.service

[Unit]
#描述服务
Description=redis
#描述服务在指定服务周后启动
After=network.target
 
#服务运行参数的设置，注意【Service】的启动、重启、停止命令都要用绝对路径
[Service]
#后台运行的形式
Type=forking
#服务具体运行的命令
ExecStart=/usr/local/bin/redis-server /etc/redis/6379.conf
#重启命令
ExecReload=/usr/local/nginx/sbin/nginx -s reload
#停止命令
ExecStop=/usr/local/bin/redis-cli -h 127.0.0.1 -p 6379 shutdown
#表示给服务分配独立的临时空间

输出日志到自定义文件

配置日志输出策略

新建rsyslog日志处理服务转发策略

[root@localhost system]# cd /etc/rsyslog.d/
[root@localhost rsyslog.d]# ls
listen.conf
[root@localhost rsyslog.d]# touch moseApi.conf
[root@localhost rsyslog.d]# touch moseJob.conf
[root@localhost rsyslog.d]# touch rocketmqNS.conf
[root@localhost rsyslog.d]# touch rocketmqBK.conf
[root@localhost rsyslog.d]# vim moseApi.conf 
[root@localhost rsyslog.d]# vim moseJob.conf 
[root@localhost rsyslog.d]# vim rocketmqNS.conf 
[root@localhost rsyslog.d]# vim rocketmqBK.conf 
[root@localhost rsyslog.d]# ls
listen.conf  moseApi.conf  moseJob.conf  rocketmqBK.conf  rocketmqNS.conf
[root@localhost rsyslog.d]#

#moseApi.conf内容
if $programname == 'mose-api' then /home/server_space/ucd/mose-admin.log
& :omusrmsg:stopp

#moseJob.conf内容
if $programname == 'mose-job' then /home/server_space/ucd/xxl-job-admin.log
& :omusrmsg:stopp

#rocketmqNS.conf内容
if $programname == 'rocketmq-ns' then /var/log/rocketmq-namesrv.log
& :omusrmsg:stopp

#rocketmqBK.conf内容
if $programname == 'rocketmq-bk' then /var/log/rocketmq-broker.log
& :omusrmsg:stopp

重启日志rsyslog服务

[root@localhost system]# systemctl restart rsyslog.service

指定服务日志处理方式

修改服务配置文件

[root@localhost system]# vim mose-api.service 
[root@localhost system]# vim mose-job.service 
[root@localhost system]# vim rocketmq-ns.service 
[root@localhost system]# vim rocketmq-bk.service

#mose-api.service变更内容
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=mose-api

#mose-job.service变更内容
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=mose-job

#rocketmq-ns.service变更内容
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=rocketmq-ns

#rocketmq-bk.service变更内容
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=rocketmq-bk

刷新服务配置文件

[root@localhost system]# systemctl daemon-reload

测试日志重定向

重启服务

[root@localhost system]# systemctl stop mose-api.service
[root@localhost system]# systemctl start mose-api.service

查看日志

[root@localhost system]# tail -200f /home/server_space/ucd/mose-admin.log

问题分析解决

问题：发现日志并未重定向写入 /home/server_space/ucd/mose-admin.log 下

查看系统日志

[root@localhost system]# tail -1000f /var/log/message

May 29 20:32:56 localhost mose-job: Copyright @ 2021-2099 bjucd.com All Rights Reserved.
May 29 20:32:56 localhost rsyslogd: action 'action 2' resumed (module 'builtin:omfile') [v8.24.0-55.el7 try http://www.rsyslog.com/e/2359 ]
May 29 20:32:56 localhost rsyslogd: file '/home/server_space/ucd/xxl-job-admin.log': open error: Permission denied [v8.24.0-55.el7 try http://www.rsyslog.com/e/2433 ]

文件赋予权限重试

[root@localhost system]# chomd -R 755 /home/server_space/ucd/xxl-job-admin.log

问题依然存在，网络查找
- 发现是selinux 开启导致rsyslog 打开文件失败
- 关闭selinux 后重启服务器测试，日志可以重定向写入
- 由于自定义的路径的context不满足rsyslogd的访问权限，所以被selinux禁止访问了
- 最终解决方案

systemd运行服务配置详解

图片防失效

rc.local服务自启动执行脚本

创建启动脚本jenkins_auto.sh

#!/bin/sh
#chkconfig: 2345 80 90
#description: 开机自启动jenkins服务

export JAVA_HOME=/home/soft/jdk
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib/dt.jar:${JAVA_HOME}/lib/tool.jar
export PATH=${JAVA_HOME}/bin:$PATH

sleep 10

nohup java -Dhudson.util.ProcessTree.disable=true -Xms10240m -Xmx10240m -jar /home/jenkins/jenkins.war --httpPort=10086 > /home/jenkins/jenkins.log 2>&1 &

赋予脚本执行权限

[root@localhost init.d]# chmod +x /etc/rc.d/init.d/jenkins_auto.sh

为脚本赋予自启动权限

[root@localhost init.d]# vim /etc/rc.d/rc.local

#!/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 'chmod +x /etc/rc.d/rc.local' to ensure
# that this script will be executed during boot.

touch /var/lock/subsys/local
/etc/rc.d/init.d/jenkins_auto.sh
~                                                                                                                                  ~

为rc.local赋予执行权限

CentOS7默认为rc.local降级了，所以给他开开执行权限

[root@localhost init.d]# chmod +x /etc/rc.d/rc.local

查看rc-local服务

如果rc-local服务是停止的，则启动rc-local服务并查看jenkins脚本是否随着自启动jenkins的Jar包
如果rc-local服务是启动的，则杀掉jenkins服务进程，重启rc-local服务并验证jenkins的Jar包是否随着自启动

[root@localhost init.d]# systemctl status rc-local

如果自启动失败，可以查看/var/log/message日志

设置rc-local服务自启动

[root@localhost init.d]# systemctl enable rc-local

通过chkconfig添加系统启动脚本

在CentOS7之前，可以通过chkconfig来配置开机自启动服务

chkconfig –-add xxx   #把服务添加到chkconfig列表
chkconfig --del xxx   #把服务从chkconfig列表中删除
chkconfig xxx on      #开启开机自动启动
chkconfig xxx off     #关闭开机自动启动
chkconfig --list      #查看所有chklist中服务
chkconfig --list xxx  #查看指定服务

在/etc/rc.d/init.d下新增脚本run.sh

#!/bin/bash
#chkconfig: 2345 80 90
#description: 开机自启动jenkins服务

export JAVA_HOME=/home/soft/jdk
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib/dt.jar:${JAVA_HOME}/lib/tool.jar
export PATH=${JAVA_HOME}/bin:$PATH

nohup java -Dhudson.util.ProcessTree.disable=true -Xms10240m -Xmx10240m -jar /home/jenkins/jenkins.war --httpPort=10086 > /home/jenkins/jenkins.log 2>&1 &

增加脚本的可执行权限

[root@localhost init.d]# chmod +x /etc/rc.d/init.d/run.sh

添加脚本到开机自动启动项目中

[root@localhost init.d]# cd /etc/rc.d/init.d
[root@localhost init.d]# chkconfig --add run.sh
[root@localhost init.d]# chkconfig run.sh on
