MyCat开机自启

MyCat开机自启

方法1、在CentOS7测试有效

1、创建软连接到init.d

以我的mycat安装目录/usr/local/mycat/bin为例

ln -s /usr/local/mycat/bin/mycat /etc/init.d/mycat

2、修改MyCat配置

修改MyCat，conf下的wrapper.conf文件，将wrapper.java.command设置为java的路径

vim /app/mycat/conf/wrapper.conf

修改内容如下：

#********************************************************************
# Wrapper Properties
#********************************************************************
# Java Application
wrapper.java.command=/home/install/jdk/jdk1.8.0_311/bin/java
wrapper.working.dir=..

3、启动，加入开机自启

# 启动
service mycat start
# 查询状态
service mycat status
# 停止
service mycat stop
# 加入开机自启
chkconfig --add mycat
# 取消开机自启
chkconfig --del mycat

方法2、在CentOS7测试无效

1、创建启动脚本

在/etc/init.d/下创建mycat.sh脚本，

vi /etc/init.d/mycat.sh

输入内容如下：

#!/bin/sh
#
# Simple Mycat init.d script conceived to work on Linux systems
# as it does use of the /proc filesystem.

### BEGIN INIT INFO
# Provides:     mycat
# Default-Start:        2 3 4 5
# Default-Stop:         0 1 6
# Short-Description:    Mycat data structure server
# Description:          Mycat data structure server. See https://github.com/MyCATApache/Mycat-Server
### END INIT INFO

EXEC=/usr/local/mycat/bin/mycat
PIDFILE=/usr/local/mycat/logs/mycat.pid

case "$1" in
    start)
        if [ -f $PIDFILE ]
        then
                echo "$PIDFILE exists, process is already running or crashed"
        else
                echo "Starting Mycat server..."
                $EXEC start
        fi
        ;;
    stop)
        if [ ! -f $PIDFILE ]
        then
                echo "$PIDFILE does not exist, process is not running"
        else
                PID=$(cat $PIDFILE)
                echo "Stopping ..."
                $EXEC stop
                while [ -x /proc/${PID} ]
                do
                    echo "Waiting for Mycat to shutdown ..."
                    sleep 1
                done
                echo "Mycat stopped"
        fi
        ;;
    *)
        echo "Please use start or stop as first argument"
        ;;
esac

2、提升启动脚本的权限

提升启动脚本权限：

chmod +x /etc/init.d/mycat.sh

3、常用命令

开机自启在CentOS7下测试没用。。

增加开机自启：chkconfig --add mycat.sh

启动mycat服务：systemctl start mycat

查看mycat状态：systemctl status mycat

停止mycat服务：systemctl stop mycat

取消开机自启：chkconfig --del mycat.sh

方法3、直接加入rc.local CentOS7测试无效

# 提升权限
chmod +x /etc/rc.d/rc.local

# 加入启动项
vi /etc/rc.d/rc.local

# 加入以下内容
/usr/local/mycat/bin/mycat start
