CentOS下编译安装nginx及配置缩略图插件的方法教程

相信大家都知道利用yum安装nginx 非常方便，但是有些插件并不会默认安装，比如 http_image_filter_module， 因此我们需要编译安装 nginx，已达到我们的目的。下面来看看详细的方法吧。

安装依赖

yum install -y pcre-devel libmxl2-devel libxslt-devel gd-devel

安装 nginx

wget http://nginx.org/download/nginx-1.9.1.tar.gz
tar -xzvf nginx-1.9.1.tar.gz
cd nginx-1.9.1
./configure\
 --user=nginx\
 --group=nginx\
 --with-http_ssl_module\
 --with-http_spdy_module\
 --with-http_realip_module\
 --with-http_addition_module\
 --with-http_xslt_module\
 --with-http_image_filter_module\
 --with-http_sub_module\
 --with-http_auth_request_module\
 --with-http_stub_status_module\
 --with-http_gzip_static_module
make
make install

安装完成后，可以使用如下命令来查看 nginx 安装的模块

[root@linux001 ~]# /usr/local/nginx/sbin/nginx -V
nginx version: nginx/1.9.1
built by gcc 4.4.7 20120313 (Red Hat 4.4.7-11) (GCC)
built with OpenSSL 1.0.1e-fips 11 Feb 2013
TLS SNI support enabled
configure arguments: --user=nginx --group=nginx --with-http_ssl_module --with-http_spdy_module --with-http_realip_module --with-http_addition_module --with-http_xslt_module --with-http_image_filter_module --with-http_sub_module --with-http_auth_request_module --with-http_stub_status_module --with-http_gzip_static_module --with-http_image_filter_module

增加启动脚本

新建文件 /etc/init.d/nginx ， 内容如下：

#!/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:  /etc/nginx/nginx.conf
# 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

make_dirs() {
 # make required directories
 user=`$nginx -V 2>&1 | grep "configure arguments:" | sed 's/[^*]*--user=\([^ ]*\).*/\1/g' -`
 if [ -z "`grep $user /etc/passwd`" ]; then
  useradd -M -s /bin/nologin $user
 fi
 options=`$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() {
 [ -x $nginx ] || exit 5
 [ -f $NGINX_CONF_FILE ] || exit 6
 make_dirs
 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 7
  $1
  ;;
 force-reload)
  force_reload
  ;;
 status)
  rh_status
  ;;
 condrestart|try-restart)
  rh_status_q || exit 0
   ;;
 *)
  echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"
  exit 2
esac

添加好 /etc/init.d/nginx 后，需要增加执行权限，然后就可以用脚本来 启动、停止 nginx 了。

chmod a+x /etc/init.d/nginx
/etc/init.d/nginx start
/etc/init.d/nginx stop
/etc/init.d/nginx restart
/etc/init.d/nginx reload

或者以服务来 启动、停止 nginx。

service nginx start
service nginx stop
service nginx restart
service nginx reload

设置自启动

chkconfig --add nginx
chkconfig --level 345 on
