RPMBUILD 打包总结
1.打包准备
制作原理图
有时候为了方便源码包的安装，和我们自己订制软件包的需求，我们会把一些源码包按照我们的需求来做成rpm包，当有了源码包就可以直接编译得到二进制安装包和其他任意包。spec file是制作rpm包最核心的部分，rpm包的制作就是根据spec file来实现的。在制作自定义rpm包的时候最好不要使用管理员进行,因为管理员权限过大，如果一个命令写错了，结果可能是灾难性的，而制件一个rpm包普通用户完全可以实现
1. 定义工作车间(可以通过rpmbuild --showrc | grep topdir查看当前的工作车间)
vim ~/.rpmmacros
%_topdir /root/myrpmbuild
wq!
2. 创建打包目录
mkdir -pv {BUILD,BUILDROOT,RPMS,SOURCES,SPECS,SRPMS}
3. 安装打包工具
yum -y install rpm-build
2.打包过程（以nginx打包实例来说明打包过程）
1. 下载源码包到~/SOURCES
cd ~/myrpmbuild/SOURCES
wget http://nginx.org/download/nginx-1.8.1.tar.gz
2. 编写nginx启动脚本（nginx.init放到~/myrpmbuild/SOURCES）
#!/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: /etc/sysconfig/nginx
# pidfile: /var/run/nginx.pid
# Source function library.
. /etc/rc.d/init.d/functions
# Source networking configuration.
. /etc/sysconfig/network
# Check that networking is up.
[ "$NETWORKING" = "no" ] && exit 0
nginx="/usr/sbin/nginx"
prog=$(basename $nginx)
NGINX_CONF_FILE="/etc/nginx/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 $?
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
}

3. fastcgi(同上)
fastcgi_params 参数
fastcgi_param GATEWAY_INTERFACE CGI/1.1;
fastcgi_param SERVER_SOFTWARE nginx;
fastcgi_param QUERY_STRING $query_string;
fastcgi_param REQUEST_METHOD $request_method;
fastcgi_param CONTENT_TYPE $content_type;
fastcgi_param CONTENT_LENGTH $content_length;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param SCRIPT_NAME $fastcgi_script_name;
fastcgi_param REQUEST_URI $request_uri;
fastcgi_param DOCUMENT_URI $document_uri;
fastcgi_param DOCUMENT_ROOT $document_root;
fastcgi_param SERVER_PROTOCOL $server_protocol;
fastcgi_param REMOTE_ADDR $remote_addr;
fastcgi_param REMOTE_PORT $remote_port;
fastcgi_param SERVER_ADDR $server_addr;
fastcgi_param SERVER_PORT $server_port;
fastcgi_param SERVER_NAME $server_name;
[root@localhost SOURCES]# ls
fastcgi_params init.nginx nginx-1.7.7.tar.gz nginx.conf
4. spec文件
cd rpmbuild/SPECS/
vim nginx.spec #此时，里面就是一个模板，直接填就可以了

5. rpm包制作
rpmbuild -ba nginx.spec 表示既制作二进制包又制作src格式包
