Centos7 编译安装Clickhouse
- 检查是否支持SSE4.2
- 安装依赖项
- 安装高版本 gcc
- 安装cmake 3
- 源码安装Clickhouse
- 启动服务
1、检查是否支持SSE4.2
grep -q sse4_2 /proc/cpuinfo && echo "SSE 4.2 supported" || echo "SSE 4.2 not supported"
2、安装依赖项
yum install git cmake ninja-build libicu-devel clang libicu-devel readline-devel mysql-devel openssl-devel unixODBC_devel bzip2 -y
3、安装高版本 gcc
wget ftp://gnu.mirror.iweb.com/gcc/gcc-7.5.0/gcc-8.2.0.tar.xz
tar xvf gcc-8.2.0.tar.xz
cd gcc-8.2.0
./contrib/download_prerequisites
mkdir build
cd build
../configure --prefix=/opt/gcc8 --enable-languages=c,c++ --disable-multilib
export THREADS=$(grep -c ^processor /proc/cpuinfo)
make -j $THREADS
make install
添加软连接，不改变系统默认的值
cd /opt/gcc8/bin/
ln -s gcc cc
ln -s g++ g++-8
ln -s gcc gcc-8
ln -s /opt/gcc8/bin/* /usr/local/bin/
添加环境变量
vim ~/.bashrc
export GCC7_HOME=/opt/gcc8
export PATH=$GCC8_HOME/bin:$PATH
export CC=gcc-8
export CXX=g++-8
source ~/.bashrc
验证版本：
4、安装cmake 3，保留替换系统默认的
准备软件
wget https://cmake.org/files/v3.14/cmake-3.14.5-Linux-x86_64.tar.gz
tar zxvf cmake-3.14.5-Linux-x86_64.tar.gz -C /opt
ln -s cmake-3.14.5-Linux-x86_64 cmake
添加环境变量
vim /etc/profile
export CMAKE_HOME=/opt/cmake
export PATH=$CMAKE_HOME/bin:$PATH
source /etc/profile
5、安装ninja
wget https://github.com/ninja-build/ninja/releases/download/v1.9.0/ninja-linux.zip
unzip ninja-linux.zip -d /usr/local/bin/
测试版本：
# ninja --version
1.9.0
6、源码安装Clickhouse
#clone 源码
git clone https://github.com/ClickHouse/ClickHouse
cd ClickHouse
git submodule sync
git submodule update --init --recursive #这个过程会比较长，需要下载很多依赖包
切换分支
git tag -l
git checkout master
mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX=/usr/local/clickhouse ../
ninja clickhouse
注意：
这里编译安装后，并没有在指定路径下生产clickhouse目录
编译成功，显示如下：
#将配置文件copy 到/usr/local/clickhouse/etc
mkdir -p /usr/local/clickhouse/etc
cd ../dbms/programs/server
cp config.xml /usr/local/clickhouse/etc
cp users.xml /usr/local/clickhouse/etc
#将clickhouse执行文件copy 到/usr/local/clickhouse/bin
mkdir -p /usr/local/clickhouse/bin
cp dbms/programs/clickhouse /usr/local/clickhouse/bin
查看clickhouse命令帮助
7、启动服务
启动clickhouse-server
clickhouse server --config-file=/usr/local/clickhouse/etc/config.xml
启动客户端
clickhouse client
clickhouse client --host=example.com
clickhouse client -m #多线程
