Linux中添加service启动

第一步：

编写nginx文件，放入/etc/init.d/

nginx文件内容如下，粉红色部分为自己实际nginx安装的路径。

#!/bin/bash

# nginx Startup script for the Nginx HTTP Server # it is v.0.0.2 version. # chkconfig: - 85 15 # description: Nginx is a high-performance web and proxy server. # It has a lot of features, but it's not for everyone.  # processname: nginx # pidfile: /var/run/nginx.pid # config: /usr/local/nginx/conf/nginx.conf nginxd=/usr/local/nginx/sbin/nginx nginx_config=/usr/local/nginx/conf/nginx.conf nginx_pid=/var/run/nginx.pid RETVAL=0 prog="nginx" # Source function library. . /etc/rc.d/init.d/functions # Source networking configuration. . /etc/sysconfig/network # Check that networking is up. [ ${NETWORKING} = "no" ] && exit 0 [ -x $nginxd ] || exit 0 # Start nginx daemons functions. start() { if [ -e $nginx_pid ];then echo "nginx already running...." exit 1 fi echo -n $"Starting $prog: " daemon $nginxd -c ${nginx_config} RETVAL=$? echo [ $RETVAL = 0 ] && touch /var/lock/subsys/nginx return $RETVAL } # Stop nginx daemons functions. stop() { echo -n $"Stopping $prog: " killproc $nginxd RETVAL=$? echo [ $RETVAL = 0 ] && rm -f /var/lock/subsys/nginx /var/run/nginx.pid } # reload nginx service functions. reload() { echo -n $"Reloading $prog: " #kill -HUP `cat ${nginx_pid}` killproc $nginxd -HUP RETVAL=$? echo } # See how we were called. case "$1" in start) start ;; stop) stop ;; reload) reload ;; restart) stop start ;; status) status $prog RETVAL=$? ;; *) echo $"Usage: $prog {start|stop|restart|reload|status|help}" exit 1 esac exit $RETVAL

 

第二步：

执行

chkconfig --add /etc/init.d/nginx
chmod 755 /etc/init.d/nginx
chkconfig --add nginx

如果想随系统启动就执行

/sbin/chkconfig --level 345 nginx on

 

 

第三步

nginx启动、停止、无间断服务重启，可选  start | stop | restart | reload | status |  help

service nginx start

service nginx stop

service nginx reload

 

 

Tomcat添加service启动

1. 进入/etc/init.d/目录 cd /etc/init.d
2. 新建nginx文件，并编辑。vi tomcat
3. 粘贴以下内容：#!/bin/bash # description: Tomcat8 Start Stop Restart # processname: tomcat8 # chkconfig: 234 20 80 #jdk menu JAVA_HOME=/usr/local/java/jdk1.8.0_191 export JAVA_HOME PATH=$JAVA_HOME/bin:$PATH export PATH #tomcat menu CATALINA_HOME=/usr/local/tomcat/ case $1 in start) sh $CATALINA_HOME/bin/startup.sh ;; stop) sh $CATALINA_HOME/bin/shutdown.sh ;; restart) ps ax --width=1000 | grep "[o]rg.apache.catalina.startup.Bootstrap" | awk '{printf $1 " "}' | wc | awk '{print $2}' > /tmp/tomcat_process_count.txt read line < /tmp/tomcat_process_count.txt if [ $line -gt 0 ]; then sh $CATALINA_HOME/bin/shutdown.sh sh $CATALINA_HOME/bin/startup.sh else sh $CATALINA_HOME/bin/startup.sh fi ;; status) # # Restart Tomcat # ps ax --width=1000 | grep "[o]rg.apache.catalina.startup.Bootstrap" | awk '{printf $1 " "}' | wc | awk '{print $2}' > /tmp/tomcat_process_count.txt read line < /tmp/tomcat_process_count.txt if [ $line -gt 0 ]; then echo -n "tomcat ( pid " ps ax --width=1000 | grep "[o]rg.apache.catalina.startup.Bootstrap" | awk '{printf $1 " "}' echo ") is running " else echo "tomcat is stopped" fi ;; esac exit 0

4. 将上面这个文件设置成可执行文件
   chmod a+x tomcat

5. 系统服务（开机自启）

• 添加系统服务
  chkconfig --add tomcat
• 关闭
  chkconfig tomcat off

6. 查看是否添加Tomcat系统服务
   chkconfig --list tomcat

• 查看所有的service服务
  chkconfig --list

# Stop nginx daemons functions.
stop() {
        echo -n $"Stopping $prog: "
        killproc $nginxd
        RETVAL=$?


7. 测试

service tomcat start(stop/restart/status)
