linux非root用户安装rabbitmq

　　因为rabbitmq是用erlang语言写的，所以装rabbitmq前第一步得先装erlang。

　　我们到erlang官网https://www.erlang.org/downloads下载安装包，最新版本是22.0，下载时又被windows禁掉了，退而求其次，下21.3版本吧：

　　下完后通过rz上传至wlf用户soft目录下，执行解压：

$ tar xvf otp_src_21..tar

　　注意编译前需要借用root用户通过yum install命令先安装ncurses-devel和openssl-devel依赖，可以切换到root用户后执行：

yum install ncurses-devel
yum install openssl-devel

　　很遗憾，普通用户这里没法绕开root用户，除非你的机器之前已经用root安装过以上两个依赖了。通过以下命令可以查看本机是否已经存在这两个依赖：

$ rpm -qa | grep -E "ncurses-devel*|openssl-devel*"
ncurses-devel-5.9-13.20130511.el7.x86_64
openssl-devel-1.0.1e-60.el7.x86_64

　　可以发现我这里之前已经装了。

　　配置下目录前缀，通过make命令开始编译、安装，貌似编译时间有点久：

$ cd otp_src_21.3
$ ./configure --prefix=/home/wlf/erlang

　　检查成功后编译、安装一条龙：

$ make && make install

　　结束后通过bin/erl命令确认安装成功：

$ cd ~
$ cd erlang/bin
$ ./erl
Erlang/OTP  [erts-10.3] [source] [-bit] [smp::] [ds:::] [async-threads:] [hipe]

Eshell V10.  (abort with ^G)
> halt()
> .

　　halt是退出系统的方法，别忘了下面的点。

　　配置Erlang环境变量：

$ cd ~
$ vi .bash_profile

　　在bash_profile最后加入export PATH=$PATH:/home/wlf/erlang/bin这一行：

# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/.local/bin:$HOME/bin

export PATH

# Java_Home
JAVA_HOME=/home/wlf/jdk1..0_221
CLASSPATH=$JAVA_HOME/lib:$JAVA_HOME/jre/lib
PATH=$PATH:$JAVA_HOME/bin:$JAVA_HOME/jre/bin
export PATH CLASSPATH JaVA_HOME

# erlang
export PATH=$PATH:/home/wlf/erlang/bin

　　保存后让它生效：

$ source .bash_profile

　　------------------------------------------------------------------------分割线------------------------------------------------------------------------

　　搞定了erlang，再开始搞rabbitmq。同理，先去官网http://www.rabbitmq.com/download.html下载安装包，我们选通过git下载linux二进制版本的：

　　会有点慢，压缩包rabbitmq-server-generic-unix-3.7.18.tar.xz下好了通过rz上传到wlf的soft目录下，在soft目录下开始解压，需要分两步走，先解压xz，再解压tar：

$ xz -d rabbitmq-server-generic-unix-3.7..tar.xz
$ cd ..
$ tar xvf soft/rabbitmq-server-generic-unix-3.7..tar

　　rabbitmq是解压即可用的，但我们可以通过在配置文件来指定一些自定义设置，先进入配置目录：

cd rabbitmq_server-3.7./etc/rabbitmq/

　　再通过vi新增rabbitmq.env.conf指定数据节点名称和路径

#node name
NODENAME=rabbit

#data dir
MNESIA_BASE=/home/wlf/rabbitmq_server-3.7./data

　　同理，新增rabbitmq.conf指定端口等设置：

#listen port
listeners.tcp.default = 

#log dir
log.dir = /home/wlf/rabbitmq_server-3.7./logs

#open remote request
loopback_users = none

　　配置完后记得手动创建日志目录logs。最后我们再次使用vi打开bash_profile配置下环境变量：

# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/.local/bin:$HOME/bin

export PATH

# Java_Home
JAVA_HOME=/home/wlf/jdk1..0_221
CLASSPATH=$JAVA_HOME/lib:$JAVA_HOME/jre/lib
PATH=$PATH:$JAVA_HOME/bin:$JAVA_HOME/jre/bin
export PATH CLASSPATH JaVA_HOME

# erlang
export PATH=$PATH:/home/wlf/otp_src_21./bin

# rabbitmq
export PATH=$PATH:/home/wlf/rabbitmq_server-3.7./sbin

　　加上最后一行指定rabbitmq的执行目录之后，保存并用source命令让我们的配置生效。我们以后台进行方式启动rabbitmq：

$ rabbitmq-server -detatched

　　克隆会话登陆wlf，查看启动状态：

　　 可以看到启动成功，使用端口5673.

　　如果想访问管理界面，执行下管理插件安装命令即可：
