inx: [error] open() "/root/nginx/logs/nginx.pid" failed (2: No such file or directory)

这个错误是因为打开文件"/root/nginx/logs/nginx.pid"失败，原因是文件路径不存在。解决方法是检查是否有该路径，如果不存在则创建路径。你可以执行以下命令来启动nginx并指定配置文件路径：
/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

nginx: [error] invalid PID number "/usr/local/nginx/logs/nginx.pid"

在这个错误信息中，"nginx: [error] invalid PID number "/usr/local/nginx/logs/nginx.pid""，它是由于nginx在加载配置文件时遇到了无效的进程ID号。而具体原因是由于nginx在重新读取配置文件时，检测到指定的进程ID文件"/usr/local/nginx/logs/nginx.pid"无效或不存在。解决方法是检查"/usr/local/nginx/logs/nginx.pid"文件是否存在，如果不存在，则需要手动指定nginx配置文件的路径来启动nginx，即使用命令"/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf"。<span class="em">1</span><span class="em">2</span><span class="em">3</span>

linux如何把nginx写入/etc/init.d

要将Nginx写入/etc/init.d，可以按照以下步骤进行操作：

1. 创建一个新的文件，例如nginx，将其放在/etc/init.d/目录下。
2. 将以下脚本粘贴到该文件中：

#!/bin/sh
#
# nginx - this script starts and stops the nginx daemon
#
# chkconfig:   - 85 15
# description:  NGINX is an HTTP(S) server, HTTP(S) reverse \
#               proxy and IMAP/POP3 proxy server
# processname: nginx
# config:      /usr/local/nginx/conf/nginx.conf
# pidfile:     /usr/local/nginx/logs/nginx.pid
# Source function library.
. /etc/rc.d/init.d/functions
# Source networking configuration.
. /etc/sysconfig/network
# Check that networking is up.
[ "$NETWORKING" = "no" ] && exit 0
nginx="/usr/local/nginx/sbin/nginx"
prog=$(basename $nginx)
NGINX_CONF_FILE="/usr/local/nginx/conf/nginx.conf"
[ -f /etc/sysconfig/nginx ] && . /etc/sysconfig/nginx
lockfile=/var/lock/subsys/nginx
start() {
    [ -x $nginx ] || exit 5
    [ -f $NGINX_CONF_FILE ] || exit 6
    echo -n $"Starting $prog: "
    daemon $nginx -c $NGINX_CONF_FILE
    retval=$?
    echo
    [ $retval -eq 0 ] && touch $lockfile
    return $retval
}
stop() {
    echo -n $"Stopping $prog: "
    killproc $prog -QUIT
    retval=$?
    echo
    [ $retval -eq 0 ] && rm -f $lockfile
    return $retval
}
restart() {
    configtest || return $?
    stop
    sleep 1
    start
}
reload() {
    configtest || return $?
    echo -n $"Reloading $prog: "
    killproc $nginx -HUP
    RETVAL=$?
    echo
}
force_reload() {
    restart
}
configtest() {
    $nginx -t -c $NGINX_CONF_FILE
}
rh_status() {
    status $prog
}
rh_status_q() {
    rh_status >/dev/null 2>&1
}
case "$1" in
    start)
        rh_status_q && exit 0
        $1
        ;;
    stop)
        rh_status_q || exit 0
        $1
        ;;
    restart|configtest)
        $1
        ;;
    reload)
        rh_status_q || exit 0
        $1
        ;;
    force-reload)
        force_reload
        ;;
    status)
        rh_status
        ;;
    condrestart|try-restart)
        rh_status_q || exit 0
        restart
        ;;
    *)
        echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"
        exit 2
esac

3. 修改脚本中的变量，例如nginx路径和NGINX_CONF_FILE等。
4. 保存并关闭文件，然后执行以下命令添加执行权限：

chmod +x /etc/init.d/nginx

5. 最后，可以使用以下命令来启动、停止、重启或检查Nginx的状态：

service nginx start
service nginx stop
service nginx restart
service nginx status
