|
||
|
||
:::info You don't have to build ClickHouse yourself!
|
||
You can install pre-built ClickHouse as described in [Quick Start](https://clickhouse.com/#quick-start). Follow **macOS (Intel)** or **macOS (Apple silicon)** installation instructions.
|
||
:::
|
||
|
||
The build works on x86_64 (Intel) and arm64 (Apple Silicon) based on macOS 10.15 (Catalina) or higher with Homebrew's vanilla Clang.
|
||
|
||
:::note
|
||
It is also possible to compile with Apple's XCode `apple-clang`, but it's strongly discouraged.
|
||
:::
|
||
|
||
## Install Homebrew {#install-homebrew}
|
||
|
||
First install [Homebrew](https://brew.sh/)
|
||
|
||
## For Apple's Clang (discouraged): Install XCode and Command Line Tools {#install-xcode-and-command-line-tools}
|
||
|
||
Install the latest [XCode](https://apps.apple.com/am/app/xcode/id497799835?mt=12) from App Store.
|
||
|
||
Open it at least once to accept the end-user license agreement and automatically install the required components.
|
||
|
||
Then, make sure that the latest Command Line Tools are installed and selected in the system:
|
||
|
||
``` bash
|
||
sudo rm -rf /Library/Developer/CommandLineTools
|
||
sudo xcode-select --install
|
||
```
|
||
|
||
## Install Required Compilers, Tools, and Libraries {#install-required-compilers-tools-and-libraries}
|
||
|
||
``` bash
|
||
brew update
|
||
brew install ccache cmake ninja libtool gettext llvm gcc binutils grep findutils
|
||
```
|
||
|
||
## Checkout ClickHouse Sources {#checkout-clickhouse-sources}
|
||
|
||
``` bash
|
||
git clone --recursive git@github.com:ClickHouse/ClickHouse.git
|
||
# ...alternatively, you can use https://github.com/ClickHouse/ClickHouse.git as the repo URL.
|
||
```
|
||
|
||
## Build ClickHouse {#build-clickhouse}
|
||
|
||
To build using Homebrew's vanilla Clang compiler (the only **recommended** way):
|
||
|
||
``` bash
|
||
cd ClickHouse
|
||
mkdir build
|
||
export PATH=$(brew --prefix llvm)/bin:$PATH
|
||
export CC=$(brew --prefix llvm)/bin/clang
|
||
export CXX=$(brew --prefix llvm)/bin/clang++
|
||
cmake -G Ninja -DCMAKE_BUILD_TYPE=RelWithDebInfo -S . -B build
|
||
cmake --build build
|
||
# The resulting binary will be created at: build/programs/clickhouse
|
||
```
|
||
|
||
To build using XCode native AppleClang compiler in XCode IDE (this option is only for development builds and workflows, and is **not recommended** unless you know what you are doing):
|
||
|
||
``` bash
|
||
cd ClickHouse
|
||
rm -rf build
|
||
mkdir build
|
||
cd build
|
||
XCODE_IDE=1 ALLOW_APPLECLANG=1 cmake -G Xcode -DCMAKE_BUILD_TYPE=Debug -DENABLE_JEMALLOC=OFF ..
|
||
cmake --open .
|
||
# ...then, in XCode IDE select ALL_BUILD scheme and start the building process.
|
||
# The resulting binary will be created at: ./programs/Debug/clickhouse
|
||
```
|
||
|
||
## Caveats {#caveats}
|
||
|
||
If you intend to run `clickhouse-server`, make sure to increase the system’s `maxfiles` variable.
|
||
|
||
:::note
|
||
You’ll need to use sudo.
|
||
:::
|
||
|
||
To do so, create the `/Library/LaunchDaemons/limit.maxfiles.plist` file with the following content:
|
||
|
||
``` xml
|
||
<?xml version="1.0" encoding="UTF-8"?>
|
||
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN"
|
||
"http://www.apple.com/DTDs/PropertyList-1.0.dtd">
|
||
<plist version="1.0">
|
||
<dict>
|
||
<key>Label</key>
|
||
<string>limit.maxfiles</string>
|
||
<key>ProgramArguments</key>
|
||
<array>
|
||
<string>launchctl</string>
|
||
<string>limit</string>
|
||
<string>maxfiles</string>
|
||
<string>524288</string>
|
||
<string>524288</string>
|
||
</array>
|
||
<key>RunAtLoad</key>
|
||
<true/>
|
||
<key>ServiceIPC</key>
|
||
<false/>
|
||
</dict>
|
||
</plist>
|
||
```
|
||
|
||
Give the file correct permissions:
|
||
|
||
``` bash
|
||
sudo chown root:wheel /Library/LaunchDaemons/limit.maxfiles.plist
|
||
```
|
||
|
||
Validate that the file is correct:
|
||
|
||
``` bash
|
||
plutil /Library/LaunchDaemons/limit.maxfiles.plist
|
||
```
|
||
|
||
Load the file (or reboot):
|
||
|
||
``` bash
|
||
sudo launchctl load -w /Library/LaunchDaemons/limit.maxfiles.plist
|
||
```
|
||
|
||
To check if it’s working, use the `ulimit -n` or `launchctl limit maxfiles` commands.
|
||
|
||
## Running ClickHouse server
|
||
|
||
``` bash
|
||
cd ClickHouse
|
||
./build/programs/clickhouse-server --config-file ./programs/server/config.xml
|
||
```
