mesos 安装

软件需求：

g++(gcc-c++)
gcc
sun-jdk6
python2.6
python26-devel
git
subversion
环境变量JAVA_HOME也需要设置下

环境一定要干净

安装：

./configure.template.centos-5.4-64 基本上就差不多了，但是configure.template.centos-5.4-64中的第一行export LDFLAGS=-lunwind-x86_64 需要去掉，否则在配置的时候会出错。

$(dirname $0)/configure \
--with-python-headers=/usr/include/python2.6 \
--with-java-home=$JAVA_HOME\
--with-java-headers=$JAVA_HOME/include\
--with-webui \
--with-included-zookeeper $@
然后就make, make install

make的时候不能为了图速度就使用并行编译，有时候会出错的。

mesos就安装在/usr/local/mesos/ 下

可以用三种方式配置mesos

1. 启动参数，直接在MESOS_HOME/bin/mesos-master –conf=”….” –failover_timeout=…. …..

2. 环境变量，使用MESOS_*作为开头

3. 使用配置文件MESOS_HOME/conf是配置目录。将配置文件写在这个文件夹中。

运行：

启动Master：

–conf 指定配置目录，默认使用 <install location>/conf
–failover_timeout failover 的超时时间，单位秒。默认 86400秒
–ip 侦听ip地址
–log_buf_secs 缓冲多少秒的日志消息
–log_dir 日志存放目录(默认: MESOS_HOME/logs)
–port or -p 侦听端口，默认5050
–[no-]quiet (or [no-]q) 不打印标准错误输出stderr (默认: false)
–[no-]root_submissions root用户能启动mesosr(默认: true)
–slaves Initial slaves that should be considered part of this cluster (or if using ZooKeeper a URL) (default: *)
–url or -u URL used for leader election
–webui_port or -w Web UI port (default: 8080)
eg：

bin/mesos-master –log_dir=/home/yuquan.nq/dev/log/mesos &

启动slave：

bin/mesos-slave –help

Usage: bin/mesos-slave –master=URL [...]

URL may be one of:

mesos://id@host:port

zoo://host1:port1,host2:port2,…

zoofile://file where file contains a host:port pair per line

Supported options:

–attributes=VAL Attributes of machine
–conf=VAL Specifies a config directory from which to read Mesos config files. The Mesos binaries use <install location>/conf by default
–executor_shutdown_timeout_seconds=VAL Amount of time (in seconds) to wait for an executor to shut down (default: 5)
–frameworks_home=VAL Directory prepended to relative executor paths (default: MESOS_HOME/frameworks)
