openshift编译安装nginx

2013-4-25 王健宇 Linux

前提：已经创建DIY APP，并SSH到APP。以下命令在SSH中操作。

环境变量自行查看

env

查看一下cpu信息

cat /proc/cpuinfo

下载zlib备用

cd $OPENSHIFT_TMP_DIR
wget http://zlib.net/zlib-1.2.7.tar.gz
tar -zxvf zlib-1.2.7.tar.gz

下载pcre备用，url重写需要

cd $OPENSHIFT_TMP_DIR
wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.32.tar.bz2
tar -xjvf pcre-8.32.tar.bz2

下面编译nginx

cd $OPENSHIFT_TMP_DIR
wget http://nginx.org/download/nginx-1.3.15.tar.gz
tar -zxvf nginx-1.3.15.tar.gz
rm -rf nginx-1.3.14.tar.gz
rm -rf nginx-1.3.14
cd nginx-1.3.15
make clean

nginx安装在$OPENSHIFT_DATA_DIR/nginx，物理路径自行查看

echo $OPENSHIFT_DATA_DIR

配置文件在

        }
        if (!-e $request_filename){
            rewrite /. /index.php last;
        }
        # 删到这里为止
    }
}

保存配置文件后开始启动nginx
先把自带的testrubyserver停掉，这占用着8080端口呢

killall ruby

启动nginx，编辑启动文件

vi ~/app-root/repo/.openshift/action_hooks/start

内容为：

#!/bin/bash
# The logic to start up your application should be put in this
# script. The application will work only if it binds to
# $OPENSHIFT_INTERNAL_IP:8080
# 注释掉testrubyserver的启动
# nohup $OPENSHIFT_REPO_DIR/diy/testrubyserver.rb $OPENSHIFT_INTERNAL_IP $OPENSHIFT_REPO_DIR/diy > $OPENSHIFT_HOMEDIR/diy-0.1/logs/server.log 2>&1 &
# 添加nginx启动命令
nohup $OPENSHIFT_DATA_DIR/nginx/sbin/nginx > $OPENSHIFT_DIY_LOG_DIR/server.log 2>&1 &

保存退出vi
编辑停止命令文件

vi ~/app-root/repo/.openshift/action_hooks/stop

内容为：

#!/bin/bash
# The logic to stop your application should be put in this script.
kill `ps -ef | grep testrubyserver.rb | grep -v grep | awk '{ print $2 }'` > /dev/null 2>&1
ps -ef | grep nginx | while read line
do
  kill -9 `echo $line | awk '{ print $2 }'`
done
exit 0

保存退出vi
现在可以用rhc app start|stop|restart 你的应用了。
