cd /opt/redis-5.0.4
make

# 安装
cd /opt/redis-5.0.4/src
make install PREFIX=/usr/local/redis

# 复制配置文件到安装目录
cp -a /opt/redis-5.0.4/redis.conf /usr/local/redis

# 修改配置

bind 127.0.0.1                 # line.69 注释掉

MISCONF Redis is configured to save RDB snapshots, but it is currently not able to persist on disk. Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error.

# 修改配置
vim /usr/local/redis/redis.conf

stop-writes-on-bgsave-error no # line.235 持久化失败报错 no，继续使用

# 重启redis
