Centos 7 安装RocksDB

1、安装依赖

yum -y install lrzsz git gcc gcc-c++ lz4-devel yum -y install snappy snappy-devel zlib zlib-devel bzip2 bzip2-devel lz4 lz4-devel zstd

2、下载安装cmake（gflags-2.2.2对cmake版本有要求）

curl -O   https://cmake.org/files/v3.6/cmake-3.6.0-Linux-x86_64.tar.gzmv cmake-3.6.0-Linux-x86_64.tar.gz /opt/cd /opt/tar -xvzf cmake-3.6.0-Linux-x86_64.tar.gz yum remove cmakecat >>/etc/profile <
3、安装依赖gflags
wget   https://github.com/gflags/gflags/archive/v2.2.2.tar.gz我这里是windows下载好上传的文件包tar -xvzf gflags-2.2.2.tar.gzcd gflags-2.2.2/mkdir buildcd build/cmake -DBUILD_SHARED_LIBS=ON -DBUILD_STATIC_LIBS=ON -DINSTALL_HEADERS=ON -DINSTALL_SHARED_LIBS=ON -DINSTALL_STATIC_LIBS=ON ..makemake install添加lib信息cat >>/etc/profile <
4、下载安装rocksdb
wget https://github.com/facebook/rocksdb/archive/v6.4.6.tar.gz我这里用的是windows下载的包tar -xvzf rocksdb-6.4.6.tar.gz cd rocksdb-6.4.6/mkdir buildcd buildcmake -DCMAKE_INSTALL_PREFIX=/usr/local/rocksdb ..makemake installcat >>/etc/profile <
5、ldb工具进行测试
cd rocksdb-6.4.6/build/tools/[root@es1 tools]# ./ldb -helpldb - RocksDB Toolcommands MUST specify --db= when necessaryThe following optional parameters control if keys/values are input/output as hex or as plain strings:  --key_hex : Keys are input/output as hex  --value_hex : Values are input/output as hex  --hex : Both keys and values are input/output as hexThe following optional parameters control the database internals:  --column_family= : name of the column family to operate on. default: default column family  --ttl with 'put','get','scan','dump','query','batchput' : DB supports ttl and value is internally timestamp-suffixed  --try_load_options : Try to load option file from DB.  --ignore_unknown_options : Ignore unknown options when loading option file.  --bloom_bits=  --fix_prefix_len=  --compression_type=  --compression_max_dict_bytes=  --block_size=  --auto_compaction=  --db_write_buffer_size=  --write_buffer_size=  --file_size=Data Access Commands:  put    [--ttl]  get  [--ttl]  batchput   [ ] [..] [--ttl]  scan [--from] [--to]  [--ttl] [--timestamp] [--max_keys=q]  [--start_time=:- is inclusive] [--end_time=:- is exclusive] [--no_value]  delete   deleterange    query [--ttl]    Starts a REPL shell.
