【freeswitch】编译freeswitch后Linux下设置开机自启
1、在目录/usr/lib/systemd/system下创建文件freeswitch.service，内容如下：
[Unit]
Description=FreeSWITCH
After=syslog.target network.target
After=postgresql.service postgresql-9.3.service postgresql-9.4.service mysqld.service httpd.service
[Service]
User=root
EnvironmentFile=-/etc/sysconfig/freeswitch
WorkingDirectory=/usr/local/freeswitch
ExecStart=/usr/local/freeswitch/bin/freeswitch -nc -nf $FREESWITCH_PARAMS
ExecReload=/usr/bin/kill -HUP $MAINPID
#ExecStop=/usr/local/freeswitch/bin/freeswitch -stop $FREESWITCH_PARAMS
ExecStop=/bin/kill -9 $MAINPID
[Install]
WantedBy=multi-user.target
2、在目录/etc/sysconfig下创建文件freeswitch，内容如下：
## Type: string
## Default: ""
## Config: ""
## ServiceRestart: freeswitch
#
# if not empty: parameters for freeswitch
#
FREESWITCH_PARAMS=""
3、修改用户组
cd /usr/local/
chown -R root:root freeswitch
chmod -R g+w freeswitch
4、启动命令
开机启动：systemctl enable freeswitch.service
启动服务：systemctl start freeswitch.service
结束服务：systemctl stop freeswitch.service
