安装的背景
为了监控服务器上php调用各个服务的流量和请求延迟等数据，选择了Skywalking，但是由于安装过程异常不顺利，所以写下安装过程。
1. 尝试了 pecl 安装失败
2. 按照官方文档安装，安装失败
3. lib使用的较多，文档没有全部说明
准备工作
apt install php7.4-dev # 更具自己的php版本选择
apt install php7.4-curl # 更具自己的php版本选择
apt install libcurl4-gnutls-dev libcurl4-openssl-dev build-essential libssl-dev build-essential autoconf libtool pkg-config cmake autoconf automake libtool curl make g++ unzip
安装GRPC 和 protobuf
这两个扩展的安装失败的概率比较大，建议细心检查一下。安装顺序不建议对掉。编译后整个文件夹会有4GB左右大小，占空5G多，建议在SSD上编译并且保持外网速度足够，要不然时间会非常久。
apt-get install build-essential autoconf automake libtool curl make g++ unzip pkg-config cmake -y
git clone -b v1.34.x https://github.com/grpc/grpc.git
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib:/usr/local/lib64/
# grpc
cd grpc/
git submodule update --init
mkdir -p cmake/build
cd cmake/build
cmake ../.. -DBUILD_SHARED_LIBS=ON -DgRPC_INSTALL=ON
make -j$(nproc)
make install
ldconfig
# protobuf
cd grpc/third_party/protobuf
./autogen.sh
./configure
make -j$(nproc)
make install
ldconfig
安装php扩展
这边基本是常规操作了，make的时候注意一下不能加-j会出现莫名其妙问题，扩展不大对编译时间也没太大影响。
curl -Lo v4.1.1.tar.gz https://github.com/SkyAPM/SkyAPM-php-sdk/archive/v4.1.1.tar.gz
tar zxvf v4.1.1.tar.gz
cd SkyAPM-php-sdk-4.1.1
phpize
./configure
make
sudo make install
编译后文件夹大概有 108MB 如果差距较大检查一下是不是文件有缺失。
du -d 1 -h
108M ./skyapm-php-sdk
接下来就是改php.ini等常规操作不在赘述
; Loading extensions in PHP
extension=skywalking.so
; enable skywalking
skywalking.enable = 1
; Set skyWalking collector version (5 or 6 or 7 or 8)
skywalking.version = 8
; Set app code e.g. MyProjectName
skywalking.app_code = MyProjectName
; Set grpc address
skywalking.grpc=127.0.0.1:11800
结果
php7.4 --ri skywalking
skywalking
Directive => Local Value => Master Value
skywalking.enable => On => On
skywalking.version => 6 => 6
skywalking.app_code => MyProjectName => MyProjectName
skywalking.authentication => no value => no value
skywalking.grpc => 192.168.10.5:11800 => 192.168.10.5:11800
skywalking.grpc_tls_enable => 0 => 0
skywalking.grpc_tls_pem_root_certs => no value => no value
skywalking.grpc_tls_pem_private_key => no value => no value
skywalking.grpc_tls_pem_cert_chain => no value => no value
skywalking.log_enable => 0 => 0
skywalking.log_path => /tmp => /tmp
skywalking.error_handler_enable => 0 => 0
补充说明
- 比较多的朋友在php 扩展编译的
./configure时候出现奇奇怪怪的 lib缺失问题，建议官网下载一个比较新的cmake,然后重复上面步骤。 - 扩展加载报错。试试
sudo ldconfig -v
Dockerfile
有很多朋友说还是有问题，我直接贴一个Dockerfile希望能帮到大家
