centos7 配置nginx服务、开机自动启动

环境：

centos七、nginx 1.10.1

在以上都已经安装完成，能正常启动以后

配置服务：

centos7 的服务管理 与 centos6 发生了一些变化 ，此处参考 http://www.ebanban.com/?p=476

启动、中止、重启、重载、检查服务：
6: service httpd start|stop|restart|reload|status
7: systemctl start|stop|restart|reload|status httpd.service

容许、禁止服务自启动：
6: chkconfig httpd on|off
7: system enable|disable httpd.service

列出服务：
6: chkconfig –list
7: systemctl list-unit-files –type=service 或 ls /etc/systemd/system/*.wants/

添加服务：
6: chkconfig httpd –add
7: systemctl daemon-reload

能够先经过上述命令查询是否已经配置nginx服务，若是没有

centos7：

服务文件

#systemd 下的 system 或 usr 建立 nginx.service 文件
vim /usr/lib/systemd/system/nginx.service 

#nginx服务配置到该文件中
#服务描述性的配置
[Unit]
Description=nginx - high performance web server
Documentation=http://nginx.org/en/docs/
After=network.target remote-fs.target nss-lookup.target
#服务关键配置
[Service]
Type=forking
#pid文件位置 
#要与nginx配置文件中的pid配置路径一致，这个很重要，不然会服务启动失败
PIDFile=/var/run/nginx.pid
#启动前检测 nginx配置文件 是否正确
ExecStartPre=/usr/sbin/nginx -t -c /usr/local/nginx/conf/nginx.conf
#启动
ExecStart=/usr/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
#重启
ExecReload=/bin/kill -s HUP $MAINPID
#关闭
ExecStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=true
[Install]
WantedBy=multi-user.target

启动服务

systemctl start nginx.service

设置开机自启

systemctl enable nginx.service

centos6:

在 /etc/init.d 中新增 nginx 文件，内容以下

#!/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.

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.

# 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

而后设置自启

#添加服务
chkconfig --add nginx
chkconfig nginx on

启动服务

service nginx start
