Centos 7 安裝RocksDB

1、安裝依賴

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、下載安裝cmake（gflags-2.2.2對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?<<EOF

export?PATH=\$PATH:/opt/cmake-3.6.0-Linux-x86_64/bin

EOF
source?/etc/profile

3、安裝依賴gflags

wget???https://github.com/gflags/gflags/archive/v2.2.2.tar.gz
我這里是windows下載好上傳的文件包
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?<<EOF

export?LD_LIBRARY_PATH=\$LD_LIBRARY_PATH:/usr/local/lib
EOF
source?/etc/profile

4、下載安裝rocksdb

wget?https://github.com/facebook/rocksdb/archive/v6.4.6.tar.gz
我這里用的是windows下載的包
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?<<EOF

export?CPLUS_INCLUDE_PATH=\$CPLUS_INCLUDE_PATH:/usr/local/rocksdb/include/
export?LD_LIBRARY_PATH=\$LD_LIBRARY_PATH:/usr/local/rocksdb/lib64/
export?LIBRARY_PATH=\$LIBRARY_PATH:/usr/local/rocksdb/lib64/

EOF

source?/etc/profile

5、ldb工具進行測試

cd?rocksdb-6.4.6/build/tools/

[root@es1?tools]#?./ldb?-help
