nginx.lock 文件在哪里？

Question

Ans 1：您不会找到锁定文件，因为它是在启动服务器时的脚本中创建的。（检查行：）[ $retval -eq 0 ] && touch $lockfile。 pid和lock文件仅在应用程序运行时存在。当nginx运行时，可以在这里找到锁文件：/usr/local/nginx/logs/nginx.lock

Ans 2：由于您的conf文件位于默认位置（/usr/local/nginx/conf/nginx.conf），我假设nginx也将位于默认位置，即/usr/local/nginx/sbin。这需要检查。我使用的是 RHEL 6.6，并且还从源代码安装了 nginx。这是我提到的初始化脚本这里

#!/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/nginx.conf
# config:      /etc/sysconfig/nginx
# pidfile:     /var/run/nginx.pid /usr/local/nginx/logs
# Source function library.
. /etc/rc.d/init.d/functions

# Source networking configuration.

# 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=/usr/local/nginx/logs/nginx.lock

make_dirs() {
    #make required directories

   user=`$nginx -V 2>&1 | grep "configure arguments:" | sed 's/[^*]*--user=\([^ ]*\).*/\1/g' -`

   options=`$nginx -V 2>&1 | grep 'configure arguments:'`
   for opt in $options; do
       if [ `echo $opt | grep '.*-temp-path'` ]; then
           value=`echo $opt | cut -d "=" -f 2`
           if [ ! -d "$value" ]; then
               # echo "creating" $value
               mkdir -p $value && chown -R $user $value
           fi
       fi
   done
}  

start() {

    [ -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: "

    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

    start)
        rh_status_q && exit 0

        rh_status

        rh_status_q || exit 0
            ;;
    *)
        echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"
        exit 2
esac

除此之外，还需要提供文件权限

chmod 755 /etc/init.d/nginx -v

将脚本添加到默认运行级别：

chkconfig nginx on

最后一步，通过运行进行测试：

/etc/init.d/nginx start
/etc/init.d/nginx stop
/etc/init.d/nginx restart

通过导出nginx的路径，就可以直接运行nginx了。

export PATH=${PATH}:/usr/local/nginx/sbin
