原配置文件 #

.env #

DB_CONNECTION=pgsql
DB_HOST=localhost
DB_PORT=6000
DB_DATABASE=test1
DB_USERNAME=test1
DB_PASSWORD=test1


REDIS_HOST=localhost
REDIS_PASSWORD='L\Cm;=9YV$v<{4,eLs/AN4[g{dA"R4wy'
REDIS_PORT=6001

问题原因 #

1. .env变量格式错误：REDIS_PASSWORD的值被单引号包裹，而.env中变量赋值不需要加引号，这会导致单引号被当作密码的一部分。同时密码本身包含双引号"，当变量替换到被单引号包裹的redis command字段时，双引号会提前闭合外层单引号，造成shell解析器找不到匹配的闭合引号。
2. 字符串格式的command易冲突：用单引号包裹整个命令字符串，当变量值包含特殊字符（引号、反斜杠等）时，极易触发解析错误。

解决方案 #

1. 修正.env文件中的REDIS_PASSWORD #

去掉密码值的单引号，直接保留原始密码：

REDIS_PASSWORD=L\Cm;=9YV$v<{4,eLs/AN4[g{dA"R4wy

2. 修改docker-compose.yml中redis的command为数组格式 #

使用YAML数组传递命令参数，避免shell解析带来的特殊字符冲突：

redis:
  image: 'redis:alpine'
  restart: unless-stopped
  command: ["redis-server", "--requirepass", "${REDIS_PASSWORD}", "--port", "${REDIS_PORT}"]
  healthcheck:
    test: ["CMD", "redis-cli","-p","${REDIS_PORT}", "ping"]
    retries: 3
    timeout: 5s
    interval: 5s
  ports:
    - "${REDIS_PORT}"

原理说明 #

• .env文件中变量赋值不需要引号，添加引号会将引号纳入变量值本身，引发后续解析问题。
• 使用数组格式的command，Docker会直接将每个数组元素作为命令的独立参数传递，无需经过shell的字符串拆分和解析，彻底避免特殊字符导致的引号冲突。
