CentOS7服务开机自启动配置：Nginx等常用服务

📝 本文基于作者实际运维经验，已在生产环境配置多个服务的开机自启动，解决断电后服务丢失问题。

centos7各种服务的开机自启动，偶尔会断电涉及到要开的服务就很多，所以这里统一写了一些，后续会不断更新。

1.nginx自启动#

进入centos的启动目录，编写启动脚本

1
vim /usr/lib/systemd/system/nginx.service

1
#nginx 启动脚本
2
[Unit]
3
Description=nginx
4
After=network.target
5

6
[Service]
7
Type=forking
8
ExecStart=/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
9
ExecReload=/usr/local/nginx/sbin/nginx -s reload
10
ExecStop=/usr/local/nginx/sbin/nginx -s quit
11
PrivateTmp=true
12

13
[Install]
14
WantedBy=multi-user.target

1
#设置开机自启动
2
systemctl enable nginx
3

4
#查看服务状态
5
systemctl status nginx

2.jenkins自启动#

直接输入命令即可

1
systemctl enable jenkins.service

3.tomcat自启动#

进入tomcat的bin目录编辑catalina.sh文件，在这个位置加入这个语句（搜索就是esc后，按/后面输入搜索的内容）

1
vim catalina.sh
2
CATALINA_PID="$CATALINA_BASE/tomcat.pid"

编辑自启动脚本

1
vim /usr/lib/systemd/system/tomcat.service

注意environment的位置是电脑java环境的位置，tomcat的位置也要替换

1
#tomcat自启动脚本
2
[Unit]
3
Description=Tomcat
4
After=syslog.target network.target remote-fs.target nss-lookup.target
5

6
[Service]
7
Type=forking
8

9
Environment="JAVA_HOME=/usr/java/jdk1.8.0_11"
10

11
PIDFile=/opt/tomcat/apache-tomcat-8.5.69/tomcat.pid
12
ExecStart=/opt/tomcat/apache-tomcat-8.5.69/bin/startup.sh
13
ExecStop=/bin/kill -s QUIT $MAINPID
14
ExecReload=/bin/kill -s HUP $MAINPID
15
PrivateTmp=true
16

17
[Install]
18
WantedBy=multi-user.target

1
#设置生效
2
systemctl daemon-reload
3
#开机自启
4
systemctl enable tomcat.service
5
#查看状态
6
systemctl status tomcat.service
7
#启动服务
8
systemctl start tomcat.service

4.oracle自启动#

找到这个路径/xxx/product/11.2.0/db_1/bin/，编写启动脚本（附在后面），然后修改为可执行，再创建软连接

1
#编写开机启动脚本（xxx表示自己的路径）
2
vim oracledb
3

4
#修改脚本为可执行
5
chmod a+x oracledb
6

7
#创建软链接（一定要用绝对路径）
8
ln -s xxx/oracledb /etc/rc.d/init.d/oracledb
9

10
#授权
11
chmod 755 /etc/rc.d/init.d/
12

13
#添加服务
14
chkconfig --add oracledb
15

16
#修改oracle启动配置（N改Y）
17
vim /etc/oratab
18
orcl:xxx/product/11.2.0/dbhome_1:Y
19

20
#开关
21
service oracledb stop
22
service oracledb start

1
#!/bin/sh
2
# chkconfig: 35 80 10

# description: Oracle auto start-stop script.
