准备工作
- 下载Erlang安装包:如果在线安装过慢,可以选择直接从官网https://www.erlang.org/downloads下载
wget http://erlang.org/download/otp_src_22.0-rc2.tar.gz
- 下载rabbitmq-server安装包
wget wget https://github.com/rabbitmq/rabbitmq-server/releases/download/v3.8.2/rabbitmq-server-3.8.2-1.el7.noarch.rpm
安装Erlang
- 安装依赖类库:
- yum -y install gcc-c++
- yum -y install ncurses-devel
- yum -y install openssl-devel
- yum -y install unixODBC-devel
- 创建目录(安装指定目录):mkdir /usr/local/erlang
- 打开目录 cd otp_src_22.2/
- 安装至指定目录: ./configure --prefix=/usr/local/erlang --without-Javac
- make && make install
- 编译&安装完成以后配置Erlang环境变量:vim /etc/profile
- 追加环境变量到文件末尾:export PATH=$PATH:/usr/local/erlang/bin
-
source /etc/profile
安装RabbitMQ
- 加载源:rpm -ivh --nodeps rabbitmq-server-3.8.2-1.el7.noarch.rpm
- 如果linux的防火墙开启时,还需执行以下操作
- firewall-cmd --zone=public --add-port=15672/tcp --permanent
- firewall-cmd --zone=public --add-port=5672/tcp --permanent
- firewall-cmd --reload
- 启动:
- rabbitmq-plugins enable rabbitmq_management
- rabbitmq-server
- 后台启动:rabbitmq-server -detached
- 创建登录账号、密码:rabbitmqctl add_user [账号] [密码]
- 授管理员权限:rabbitmqctl set_user_tags [账号] administrator
- 授权用户到虚拟机(/):rabbitmqctl set_permissions -p / [账号] '.*' '.*' '.*'
- 配置开机自启动:
- 添加自启动脚本:
- 在/etc/init.d目录下新建一个rabbitmq-server文件,内容如下:
#!/bin/sh # # rabbitmq-server RabbitMQ broker # # chkconfig: - 80 05 # description: Enable AMQP service provided by RabbitMQ # ### BEGIN INIT INFO # Provides: rabbitmq-server # Required-Start: $remote_fs $network # Required-Stop: $remote_fs $network # Description: RabbitMQ broker # Short-Description: Enable AMQP service provided by RabbitMQ broker ### END INIT INFO # Source function library. . /etc/init.d/functions export HOME=/root PATH=/sbin:/usr/sbin:/bin:/usr/bin NAME=rabbitmq-server #DAEMON=/usr/sbin/${NAME} #CONTROL=/usr/sbin/rabbitmqctl DAEMON=/server/rabbitmq/sbin/${NAME} CONTROL=/server/rabbitmq/sbin/rabbitmqctl DESC=rabbitmq-server USER=root ROTATE_SUFFIX= INIT_LOG_DIR=/var/log/rabbitmq PID_FILE=/var/run/rabbitmq/pid START_PROG="daemon" LOCK_FILE=/var/lock/subsys/$NAME test -x $DAEMON || exit 0 test -x $CONTROL || exit 0 RETVAL=0 set -e [ -f /etc/default/${NAME} ] && . /etc/default/${NAME} ensure_pid_dir () { PID_DIR=`dirname ${PID_FILE}` if [ ! -d ${PID_DIR} ] ; then mkdir -p ${PID_DIR} chown -R ${USER}:${USER} ${PID_DIR} chmod 755 ${PID_DIR} fi } remove_pid () { rm -f ${PID_FILE} rmdir `dirname ${PID_FILE}` || : } start_rabbitmq () { status_rabbitmq quiet if [ $RETVAL = 0 ] ; then echo RabbitMQ is currently running else RETVAL=0 ensure_pid_dir set +e RABBITMQ_PID_FILE=$PID_FILE $START_PROG $DAEMON \ > "${INIT_LOG_DIR}/startup_log" \ 2> "${INIT_LOG_DIR}/startup_err" \ 0<&- & $CONTROL wait $PID_FILE >/dev/null 2>&1 RETVAL=$? set -e case "$RETVAL" in 0) echo SUCCESS if [ -n "$LOCK_FILE" ] ; then touch $LOCK_FILE fi ;; *) remove_pid echo FAILED - check ${INIT_LOG_DIR}/startup_\{log, _err\} RETVAL=1 ;; esac fi } stop_rabbitmq () { status_rabbitmq quiet if [ $RETVAL = 0 ] ; then set +e $CONTROL stop ${PID_FILE} > ${INIT_LOG_DIR}/shutdown_log 2> ${INIT_LOG_DIR}/shutdown_err RETVAL=$? set -e if [ $RETVAL = 0 ] ; then remove_pid if [ -n "$LOCK_FILE" ] ; then rm -f $LOCK_FILE fi else echo FAILED - check ${INIT_LOG_DIR}/shutdown_log, _err fi else echo RabbitMQ is not running RETVAL=0 fi } status_rabbitmq() { set +e if [ "$1" != "quiet" ] ; then $CONTROL status 2>&1 else $CONTROL status > /dev/null 2>&1 fi if [ $? != 0 ] ; then RETVAL=3 fi set -e } rotate_logs_rabbitmq() { set +e $CONTROL rotate_logs ${ROTATE_SUFFIX} if [ $? != 0 ] ; then RETVAL=1 fi set -e } restart_running_rabbitmq () { status_rabbitmq quiet if [ $RETVAL = 0 ] ; then restart_rabbitmq else echo RabbitMQ is not runnning RETVAL=0 fi } restart_rabbitmq() { stop_rabbitmq start_rabbitmq } case "$1" in start) echo -n "Starting $DESC: " start_rabbitmq echo "$NAME." ;; stop) echo -n "Stopping $DESC: " stop_rabbitmq echo "$NAME." ;; status) status_rabbitmq ;; rotate-logs) echo -n "Rotating log files for $DESC: " rotate_logs_rabbitmq ;; force-reload|reload|restart) echo -n "Restarting $DESC: " restart_rabbitmq echo "$NAME." ;; try-restart) echo -n "Restarting $DESC: " restart_running_rabbitmq echo "$NAME." ;; *) echo "Usage: $0 {start|stop|status|rotate-logs|restart|condrestart|try-restart|reload|force-reload}" >&2 RETVAL=1 ;; esac exit $RETVAL
-
- 根据实际情况修改上面内容中
# 增加了Erlang环境路径 PATH=/sbin:/usr/sbin:/bin:/usr/bin:/usr/local/erlang/bin # 服务脚本 DAEMON=/server/rabbitmq/sbin/${NAME} CONTROL=/server/rabbitmq/sbin/rabbitmqctl DESC=rabbitmq-server USER=root # 日志目录 INIT_LOG_DIR=/data/soft/rabbitmq_server-3.7.9/var/log/rabbitmq # pid文件,查找命令命令:find / -name rabbit*.pid PID_FILE=/var/lib/rabbitmq/mnesia/rabbit@linux-dev.pid
-
- 设置执行权限,命令:chmod a+x /etc/init.d/rabbitmq-server
- 添加开机启动项:
- 添加命令:chkconfig --add /etc/init.d/rabbitmq-server
- 查看启动项,命令:chkconfig --list
- 需要设置rabbitmq-server启动命令:chkconfig rabbitmq-server on
- 关闭命令为:chkconfig rabbitmq-server off
- 删除命令为:chkconfig --del rabbitmq-server
- 执行命令reboot,重启服务器即可验证nginx开机启动
安装 RabbitMQ延迟队列插件
在正常项目开发中,我们常常会遇到延迟消费的需求;所以我们在安装完RabbitMQ服务后,还需要安装对应延迟队列的插件,以方便满足业务需求。
- 下载插件,注意要下载至你rabbitmq服务器的plugins目录下,例如:/usr/lib/rabbitmq/plugins
wget https://github.com/rabbitmq/rabbitmq-delayed-message-exchange/releases/download/v3.8.0/rabbitmq_delayed_message_exchange-3.8.0.ez
- 解压后得到文件:rabbitmq_delayed_message_exchange-20171215-3.8.0.ez
- 拷贝文件到指定目录:
cp rabbitmq_delayed_message_exchange-3.8.0.ez /usr/lib/rabbitmq/lib/rabbitmq_server-3.8.2/plugins/
- 启用插件:rabbitmq-plugins enable rabbitmq_delayed_message_exchang
