RabbitMQ单机安装及性能测试
本文使用CentOS7.9安装RabbitMQ单机环境，并进行性能测试。
1. 安装RabbitMQ
RabbitMQ依赖Erlang，版本配套关系参考官网：https://www.rabbitmq.com/docs/which-erlang。
本文安装RabbitMQ3.8.21,Erlang版本要求为23.2~24.2。
# 卸载通过yum源安装的erlang，版本不满足
$ sudo yum remove erlang-*
# 安装erlang
$ sudo yum install -y make gcc gcc-c++ m4 openssl openssl-devel ncurses-devel unixODBC unixODBC-devel java java-devel
$ sudo mkdir /usr/local/erlang
$ wget https://github.com/erlang/otp/releases/download/OTP-23.3.4.20/otp_src_23.3.4.20.tar.gz
$ tar xf otp_src_23.3.4.20.tar.gz
$ cd otp_src_23.3.4.20/
$ sudo ./configure --prefix=/usr/local/erlang
$ sudo make && sudo make install
# 配置环境变量
$ sudo vim /etc/profile
######### 添加如下内容 ###############
PATH=$PATH:/usr/local/erlang/bin
$ sudo source /etc/profile
# 查看erlang版本
$ sudo erl -version
Erlang (SMP,ASYNC_THREADS,HIPE) (BEAM) emulator version 11.2.2.18# 安装rabbitmq-server
$ wget https://github.com/rabbitmq/rabbitmq-server/releases/download/v3.8.21/rabbitmq-server-generic-unix-3.8.21.tar.xz
$ tar xf rabbitmq-server-generic-unix-3.8.21.tar.xz
$ sudo mv rabbitmq_server-3.8.21/ /usr/local/# 添加环境变量
$ sudo vim /etc/profile
export RABBITMQ_HOME=/usr/local/rabbitmq_server-3.8.21/sbin
export PATH=$RABBITMQ_HOME:$PATH# 重载一下环境变量
$ sudo source /etc/profile# 添加web管理插件
$ sudo rabbitmq-plugins enable rabbitmq_management# 找到rabbitmq.conf.example和advanced.config.example文件，将.example去掉，拷贝到/usr/local/rabbitmq_server-3.8.21/etc/rabbitmq目录下。
# 配置文件实例：https://www.rabbitmq.com/docs/configure#config-file
$ mv rabbitmq.conf.example rabbitmq.conf
$ mv advanced.config.example advanced.config# 修改rabbitmq.conf文件，取消注释如下两行（91、97行），并将geust从loopback_users中移除。
$ sudo vim rabbitmq.conf
{loopback_users, []},
loopback_users.guest = false# 后台启动
$ sudo rabbitmq-server -detached# 停止
$ sudo rabbitmqctl stop
2. PerfTest测试Rabbitmq性能
2.1 PerfTest安装
PerfTest也是从Bintray和GitHub发布的二进制版本库中分发的。如果需要将它作为库，也可以在Maven Central上使用。
参考：
官网：https://perftest.rabbitmq.com/
GitHub:https://github.com/rabbitmq/rabbitmq-perf-test/releases

# 下载解压
$ wget https://github.com/rabbitmq/rabbitmq-perf-test/releases/download/v2.20.0/rabbitmq-perf-test-2.20.0-bin.zip
$ unzip rabbitmq-perf-test-2.20.0-bin.zip
$ cd rabbitmq-perf-test-2.20.0/bin/
