Seata运行环境构建(docker版)

目录

• 安装
  • 1.拉取镜像
  • 2.创建挂在目录并创建文件
  • 3.生成容器并启动
  • 4.参考

安装

1.拉取镜像

docker pull seataio/seata-server

2.创建挂在目录并创建文件

### 创建挂在的目录
mkdir -p /usr/local/docker/seata/config
cd /usr/local/docker/seata/config
### 创建配置文件 registry.conf 用于配置注册中心，同时配置了seata的配置信息存放，这里将seata的配置信息放到了nacos中
touch registry.conf
vi registry.conf
---------------
registry {
  # file 、nacos 、eureka、redis、zk、consul、etcd3、sofa
  type = "nacos"
 
  nacos {
    application = "seata-server"
    serverAddr = "192.168.58.222:8848"
    namespace = ""
    cluster = "default"
    username = "nacos"
    password = "nacos"
  }
}
 
config {
  # file、nacos 、apollo、zk、consul、etcd3
  type = "nacos"
 
  nacos {
    serverAddr = "192.168.58.222:8848"
   #这个namespace根据在nacos实际生成的来进行替换
    namespace = "fa24dce7-6d52-40a2-8ec3-ca2e148cff19"
  }
}
---------------
### 创建推送至nacos的脚本(该脚本是seata的github上提供的)
touch nacos-config.sh
---------------
while getopts ":h:p:g:t:u:w:" opt
do
  case $opt in
  h)
    host=$OPTARG
    ;;
  p)
    port=$OPTARG
    ;;
  g)
    group=$OPTARG
    ;;
  t)
    tenant=$OPTARG
    ;;
  u)
    username=$OPTARG
    ;;
  w)
    password=$OPTARG
    ;;
  ?)
    echo " USAGE OPTION: $0 [-h host] [-p port] [-g group] [-t tenant] [-u username] [-w password] "
    exit 1
    ;;
  esac
done

if [[ -z ${host} ]]; then
    host=localhost
fi
if [[ -z ${port} ]]; then
    port=8848
fi
if [[ -z ${group} ]]; then
    group="SEATA_GROUP"
fi
if [[ -z ${tenant} ]]; then
    tenant=""
fi
if [[ -z ${username} ]]; then
    username=""
fi
if [[ -z ${password} ]]; then
    password=""
fi

nacosAddr=$host:$port
contentType="content-type:application/json;charset=UTF-8"

echo "set nacosAddr=$nacosAddr"
echo "set group=$group"

failCount=0
tempLog=$(mktemp -u)
function addConfig() {
  curl -X POST -H "${contentType}" "http://$nacosAddr/nacos/v1/cs/configs?dataId=$1&group=$group&content=$2&tenant=$tenant&username=$username&password=$password" >"${tempLog}" 2>/dev/null
  if [[ -z $(cat "${tempLog}") ]]; then
    echo " Please check the cluster status. "
    exit 1
  fi
  if [[ $(cat "${tempLog}") =~ "true" ]]; then
    echo "Set $1=$2 successfully "
  else
    echo "Set $1=$2 failure "
    (( failCount++ ))
  fi
}

count=0
for line in $(cat $(dirname "$PWD")/config.txt | sed s/[[:space:]]//g); do
  (( count++ ))
	key=${line%%=*}
    value=${line#*=}
	addConfig "${key}" "${value}"
done

echo "========================================================================="
echo " Complete initialization parameters,  total-count:$count ,  failure-count:$failCount "
echo "========================================================================="

if [[ ${failCount} -eq 0 ]]; then
	echo " Init nacos config finished, please start seata-server. "
else
	echo " init nacos config fail. "
fi

### 创建seata存放在seata的配置文件config.txt，其中具体需要修改数据库部分，其他根据实际情况修改
cd ..
touch config.txt

### 进入推送脚本文件夹，执行命令推送至nacos，其中-t 是指定命名空间，这个需要提前在nacos中创建并设置到这里
cd config
sh nacos-config.sh -h 192.168.58.222 -p 8848 -g SEATA_GROUP -t fa24dce7-6d52-40a2-8ec3-ca2e148cff19 -u nacos -w nacos

3.生成容器并启动

使用docker发布，可以参保seata官网的例子

docker run --name seata \
        -p 8091:8091 \
        -d \
        -e SEATA_IP=192.168.58.222 \
        -e SEATA_CONFIG_NAME=file:/root/seata-config/registry \
        -v /usr/local/docker/seata/config:/root/seata-config  \
        --restart=always \
        seataio/seata-server

4.参考

搭建了该运行环境，里面的一些配置细节点，如将seata的配置存放到nacos中，具体参保：seata搭建
