ubuntu下安装TexLive和Texmaker

tonglin0325

1.首先下载TexLive2015的ISO文件，挂载并安装

参考：ubuntu14.04配置中文latex完美环境（texlive+texmaker+lyx)

中文字体设置参考：ubuntu 下安装 texlive 并设置 ctex 中文套装

首先新建一个目录，文件就挂载在这个目录下

1
2
sudo mkdir /media/cdimage

挂载，并使其有读写权限

1
2
sudo mount -o rw,loop /media/lintong/工作/Ubuntu_Software/64bit_Software/TeXLive/TeXLive2015/texlive2015.iso /media/cdimage

 使用下面的命令会出现问题：mount: /dev/loop3 is write-protected, mounting read-only

1
2
sudo mount -o loop /media/XXXX/TeXLive/TeXLive2015/texlive2015.iso /media/cdimage

进入挂载目录

1
2
cd /media/cdimage

 进行安装

sudo perl install-tl -gui

echo "deb https://packages.clickhouse.com/deb stable main" | sudo tee \
    /etc/apt/sources.list.d/clickhouse.list
sudo apt-get update

sudo apt-get install -y clickhouse-server clickhouse-client

sudo service clickhouse-server start

Enter password for default user:
Password for default user is saved in file /etc/clickhouse-server/users.d/default-password.xml.
Setting capabilities for clickhouse binary. This is optional.
Cannot set 'net_admin' or 'ipc_lock' or 'sys_nice' or 'net_bind_service' capability for clickhouse binary. This is optional. Taskstats accounting will be disabled. To enable taskstats accounting you may add the required capability later manually.
 chown -R clickhouse:clickhouse '/etc/clickhouse-server'

ClickHouse has been successfully installed.

Start clickhouse-server with:
 sudo clickhouse start

Start clickhouse-client with:
 clickhouse-client --password

修改clickhouse数据路径配置，需要将所有/var/lib/clickhouse的配置修改成

1
2
sudo sed -i 's/var\/lib\/clickhouse/data01\/clickhouse/g' /etc/clickhouse-server/config.xml

创建目录

java使用gRPC框架

syntax = "proto3";

option java_multiple_files = true;
option java_package = "io.grpc.examples.helloworld";
option java_outer_classname = "HelloWorldProto";
option objc_class_prefix = "HLW";

package helloworld;

// The greeting service definition.
service Greeter {
  // Sends a greeting
  rpc SayHello (HelloRequest) returns (HelloReply) {}
}

// The request message containing the user's name.
message HelloRequest {
  string name = 1;
}

// The response message containing the greetings
message HelloReply {
  string message = 1;
}

proto定义，参考官方文档

1

https://github.com/grpc/grpc-java/blob/master/examples/src/main/proto/helloworld.proto

2.编译proto文件

1.使用protoc命令编译

在项目目录下运行编译命令，里面使用了protoc-gen-grpc-java执行文件，需要参考：编译grpc-java项目生成protoc-gen-grpc-java文件 

1
2
protoc --plugin=protoc-gen-grpc-java=./protoc-gen-grpc-java -I=./ --java_out=./src/main/java/ --grpc-java_out=./src/main/java/ ./src/main/proto/helloworld.proto

得到proto文件中定义的model和service的java代码

编译grpc-java项目生成protoc-gen-grpc-java文件

tonglin0325

使用protoc命令生成service代码的时候，需要使用如下命令

1
2
protoc --plugin=protoc-gen-grpc-java=./protoc-gen-grpc-java -I=./ --java_out=./src/main/java/ --grpc-java_out=./src/main/java/ ./src/main/proto/helloworld.proto

其中的protoc-gen-grpc-java执行文件需要自己编译生成

编译的步骤如下

git clone grpc-java项目，

1
2
git clone git@github.com:grpc/grpc-java.git

切换到使用的grpc版本，比如v1.59.0，编译这个版本需要jdk11的支持

1
2
git checkout v1.59.0

使用gradlew命令进行编译
