Swift Perfect-Ubuntu server deployment

introduction###

Perfect is a complete and powerful toolbox, framework and application server for Linux, iOS and MacOS (OS X). It provides everything that Swift engineers need to develop lightweight, maintainable, and extensible applications and other REST services for the Swift programming language for client and server-side applications.
In the next few articles I will record the Perfect framework. Those interested can see:

Personal example

The following is what I wrote using Perfect (If there is anything that can help you, I hope I can like it, and by the way, I like it on GitHub)
Github：https://github.com/LeeCenY/iRent

The first type: install using script (recommended)

Use https://github.com/PerfectlySoft/Perfect-Ubuntu to deploy Swift and Perfect

The second type: manual installation

Swift installation It is best to choose version 3.0####

• Update apt-get package management tool

apt-get update

• Install Swift dependencies

sudo apt-get install clang libicu-dev

• According to the version of Ubuntu, select the corresponding download Swift

• Import PGP key (two methods)

• method one:

gpg --keyserver hkp://pool.sks-keyservers.net \
  - - recv-keys \
  '7463 A81A 4B2E EA1B 551F  FBCF D441 C977 412B 37AD' \
  '1 BE1 E29A 084C B305 F397  D62A 9F59 7F4D 21A5 6D5F' \
  ' A3BA FD35 56A5 9079 C068  94BD 63BC 1CFE 91D3 06C6'

• Method Two:

wget -q -O - https://swift.org/keys/all-keys.asc | \
 gpg --import-

• Download Swift

wget https://swift.org/builds/swift-3.0.2-release/ubuntu1604/swift-3.0.2-RELEASE/swift-3.0.2-RELEASE-ubuntu16.04.tar.gz

• Unzip

tar xzf swift-3.0.2-RELEASE-ubuntu16.04.tar.gz

• Change file name

mv swift-3.0.2-RELEASE-ubuntu16.04 swift

• Add the Swift directory to the environment variable

echo "export PATH=/root/swift/usr/bin:"${PATH}"" >> ~/.bashrc
source ~/.bashrc

• Execute the swift --version command to check whether the Swift environment is set successfully

Swift version 3.0.2 (swift-3.0.2-RELEASE)
Target: x86_64-unknown-linux-gnu

Ubuntu deployment####

• Install git

sudo apt-get install git

• Install Perfect depends on OpenSSL, libssl-dev and uuid-dev

sudo apt-get install openssl libssl-dev uuid-dev

• Git the official example of Perfect

git clone https://github.com/PerfectlySoft/PerfectTemplate.git

• After downloading, open the PerfectTemplate file

cd PerfectTemplate

• Compile

swift build

• run

. build/debug/PerfectTemplate

• Return this similar information after successful operation

[ INFO] Starting HTTP server localhost on 0.0.0.0:8181

Possible problems in the swift build process#####

• error while loading shared libraries: libcurl.so.4: cannot open shared object file: No such file or directory
  sudo apt-get install libcurl4-openssl-dev
• warning: minimum recommended clang is version 3.6, otherwise you may encounter linker errors.
  sudo apt-get install clang-3.6
• ' EVP_aes_256_cbc_hmac_sha256'、 'EVP_aes_128_cbc_hmac_sha256' 、'EVP_aes_192_wrap'
  Ubuntu14.04 openssl 1.0.1 needs to be upgraded to at least 1.0.2 (Ubuntu16.04 solves directly)
  https://gist.github.com/mbejda/a1dabc45b32aaf8b25ae5e8d05923518
• Use MongoDB database error: header'/usr/local/include/libmongoc-1.0/mongoc.h' not foundUse MongoDB database error: header'/usr/local/include/libmongoc-1.0/mongoc.h 'not foundUsing MongoDB database error: header'/usr/local/include/libmongoc-1.0/mongoc.h' not found header "/usr/local/include/libmongoc-1.0/ mongoc.h

 ln -s /usr/include/libmongoc-1.0/ libmongoc-1.0
 or
 ln -s /usr/include/libmongoc-1.0/usr/local/include/libmongoc-1.0

• Some errors may be that some dependencies are not the latest version of clone when swift build. This is the case with my following two dependencies

. Package(url:"https://github.com/SwiftORM/MongoDB-Storm.git", majorVersion:1),.Package(url:"https://github.com/PerfectlySoft/Perfect-RequestLogger.git", majorVersion:1),

Update dependencies:
swift package update
swift build

• SPM commands include:

swift package update update dependencies
swift build builds a quick package
swift build -c release build a quick release code
swift package generate-xcodeproj Create or update Xcode project from Swift code
swift package resolve to get all dependencies

• There are also some errors that may be related to the incompatibility of the Swift version (it is better to install the Swift3.0 version)

There are many pitfalls in Ubuntu deployment, almost "from getting started to giving up". In the end, I accidentally saw Perfect-Ubuntu in Slack, and I wanted to try again. Getting started with Vapor..." (Vapor was successfully deployed, with few pits), and finally this Perfect-Ubuntu solved the database problem and deployed successfully!
