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.gz
mv 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 cmake
cat >>/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.gz
cd gflags-2.2.2/
mkdir build
cd build/
cmake -DBUILD_SHARED_LIBS=ON -DBUILD_STATIC_LIBS=ON -DINSTALL_HEADERS=ON -DINSTALL_SHARED_LIBS=ON -DINSTALL_STATIC_LIBS=ON ..
make
make 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 build
cd build
cmake -DCMAKE_INSTALL_PREFIX=/usr/local/rocksdb ..
make
make install
cat >>/etc/profile <5、ldb工具进行测试
cd rocksdb-6.4.6/build/tools/
[root@es1 tools]# ./ldb -help
