记安装RabbitMQ中踩坑

服务器为阿里云服务器,操作系统为Alibaba Cloud Linux 3.2104 64位

跟着尚硅谷视频,安装好的RabbitMQ一直启动不了,前提已经放开相应端口,搜了一圈有人说是没有修改/etc/hosts

vim /etc/hosts

这个命令打开

前两行为这个,第三行写自己ip和主机名,类似 XXX.XXX.XXX.XXX 主机名

按i插入写好后ESC键  输入:wq!   保存并退出

然而没有用,索性卸载重安装。

2、重新安装第一步  安装erlang

rpm -ivh erlang-21.3-1.el7.x86_64.rpm
error: Failed dependencies:
    libcrypto.so.10()(64bit) is needed by erlang-23.3.4.4-1.el7.x86_64
    libcrypto.so.10(OPENSSL_1.0.1_EC)(64bit) is needed by erlang-23.3.4.4-1.el7.x86_64
    libcrypto.so.10(OPENSSL_1.0.2)(64bit) is needed by erlang-23.3.4.4-1.el7.x86_64
    libcrypto.so.10(libcrypto.so.10)(64bit) is needed by erlang-23.3.4.4-1.el7.x86_64
    libnsl.so.1()(64bit) is needed by erlang-23.3.4.4-1.el7.x86_64

我记起来第一次安装的时候 在后边加了 –force (这就是导致我RabbitMQ未能启动的根本原因),所以必须安装libcrypto.so.10(OPENSSL_1.0.2)(64bit)解决问题,不能强制安装,首先安装OpenSSL 1.0.2,点如下连接


http://rpmfind.net/linux/rpm2html/search.php?query=libcrypto.so.10(OPENSSL_1.0.2)(64bit)&submit=Search+…&system=&arch=


最后一行找到,点开下载以后传到服务器中,直接安装会报冲突,所以加–force

[root@c opt]# rpm -ivh openssl-libs-1.0.2k-19.el7.x86_64.rpm --force
warning: openssl-libs-1.0.2k-19.el7.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID f4a80eb5: NOKEY

   1:openssl-libs-1:1.0.2k-19.el7     ################################# [100%]

安装成功,回到安装erlang来

[root@c opt]# rpm -ivh erlang-21.3-1.el7.x86_64.rpm 
warning: erlang-21.3-1.el7.x86_64.rpm: Header V4 RSA/SHA1 Signature, key ID 6026dfca: NOKEY
error: Failed dependencies:
        libnsl.so.1()(64bit) is needed by erlang-21.3-1.el7.x86_64

比之前报的缺依赖要少了,哈哈哈,运行

dnf install libnsl

dnf install libnsl

完成后重新试一下

[root@c opt]# rpm -ivh erlang-21.3-1.el7.x86_64.rpm 
warning: erlang-21.3-1.el7.x86_64.rpm: Header V4 RSA/SHA1 Signature, key ID 6026dfca: NOKEY
Verifying...                          ################################# [100%]

Updating / installing...
   1:erlang-21.3-1.el7                ################################# [100%]

这次成功了!!!!!

2、安装socat

[root@c opt]# yum install socat -y

3、安装rabbitmq

[root@cty opt]# rpm -ivh rabbitmq-server-3.8.8-1.el7.noarch.rpm
warning: rabbitmq-server-3.8.8-1.el7.noarch.rpm: Header V4 RSA/SHA256 Signature, key ID 6026dfca: NOKEY
Verifying...                          ################################# [100%]
Preparing...                          ################################# [100%]
Updating / installing...
   1:rabbitmq-server-3.8.8-1.el7      ################################# [100%]
[/usr/lib/tmpfiles.d/rabbitmq-server.conf:1] Line references path below legacy directory /var/run/, updating /var/run/rabbitmq → /run/rabbitmq; please update the tmpfiles.d/ drop-in file accordingly.

4、安装成功后试着启动

[root@cty opt]# /sbin/service rabbitmq-server start
Redirecting to /bin/systemctl start rabbitmq-server.service

这次启动成功了,因为查看状态  /sbin/service rabbitmq-server status

发现

唉终于完成,有问题留言,搞了好长时间,累了
