肯定有人纳闷，为啥单独把CentOS6下的nginx进行编译? 那是因为Centos6由于已经过时不再更新，而CentOS7官方还在持续更新，没必要重复造轮子，centos7可以参阅此连接： nginx-centos7-rpm
安装rpmbuild:
yum install rpm-build zlib-devel openssl-devel gcc perl-devel pam-devel unzip -y
mkdir -p /root/rpmbuild/{SOURCES,SPECS}
下载相应二进制包到SOURCES目录：
cd /root/rpmbuild/SOURCES wget https://nginx.org/download/nginx-1.20.1.tar.gz
如果需要利用service来控制Nginx，SOURCES路径中还需要准备一个nginx启动程序：
vi nginx:
#!/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

prog=$(basename $nginx)
#NGINX_CONF_FILE="/etc/nginx/nginx.conf"
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' -`
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 $?

sleep 1
start
}
reload() {

echo -n $"Reloading $prog: "

}

}

}

}
rh_status_q() {
rh_status >/dev/null 2>&1
}

esac
确保SOURCES目录中存在两个文件，一个tar.gz，一个nginx文件。
接下来进入SPEC目录中，编写nginx.spec:
cd /root/rpmbuild/SPECS/
vi nginx.spec
Name:nginx
Version:1.21.0
Release: 1
Summary: Nginx is a web server software.

注意，如果对配置文件不熟悉，请勿进行改动。
修改完配置后，我们进行编译：
rpmbuild -ba nginx.spec
编译后出现以下内容,无报错的话，表示编译成功。

rpm包存储路径为：
/root/rpmbuild/RPMS/x86_64/nginx-1.21.0-1.x86_64.rpm
源码包存储路径为：
/root/rpmbuild/SRPMS/nginx-1.21.0-1.src.rpm
注意：
如果需要对nginx设置开机自启，我们需要将nginx文件添加到chkconfig列表中：
chkconfig --add /etc/init.d/nginx
再进行开机项添加：
chkconfig nginx on
如果需要编译其他版本，对文件中的相应版本号，以及源码包进行替换即可。不再赘述。
