openEuler24.03 安装nacos2.2.3

一、部署
编译安装nacos失败提示缺少龙芯架构安装包
docker启动nacos失败，龙芯官方镜像仓库中镜像在openEuler中都无法启动
采用从docker容器中拷贝nacos 然后在宿主机启动，nacos版本为2.2.3

安装docker

yum -y install docker

使用cat启动nacos

docker run -itd --name=test --entrypoint="cat" cr.loongnix.cn/nacos/nacos-server:2.2.3

拷贝nacos

[root@cn-loongarch64-195-11 rocksdb-7.8.3]# docker ps

编译安装rocksdb
选择和nacos版本发布时间对应的rocksdb
https://github.com/facebook/rocksdb/releases/tag/v7.8.3
tar -xf rocksdb-7.8.3.tar

cd /data/servers/rocksdb-7.8.3
修改CMakeLists.txt 参考文档：https://blog.csdn.net/peihexian/article/details/125631949

数字为行号

第一处配置

在下面这个配置下新增两行

原配置

47 if(POLICY CMP0042)
48 cmake_policy(SET CMP0042 NEW)
49 endif()

新配置

if(POLICY CMP0042)
cmake_policy(SET CMP0042 NEW)
endif()
set(CMAKE_VERBOSE_MAKEFILE ON)
set(CMAKE_BUILD_TYPE,"Release")

第二处配置

这里的
69 option(WITH_SNAPPY "build with SNAPPY" OFF)
70 option(WITH_LZ4 "build with lz4" OFF)
71 option(WITH_ZLIB "build with zlib" OFF)
72 option(WITH_ZSTD "build with zstd" OFF)
全部改为ON
option(WITH_SNAPPY "build with SNAPPY" ON)
option(WITH_LZ4 "build with lz4" ON)
option(WITH_ZLIB "build with zlib" ON)
option(WITH_ZSTD "build with zstd" ON)

第三处配置

280 else()
281 if(CMAKE_SYSTEM_PROCESSOR MATCHES "^s390x" AND NOT HAS_S390X_MARCH_NATIVE)
282 set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -march=z196")
283 elseif(NOT CMAKE_SYSTEM_PROCESSOR MATCHES "^(powerpc|ppc)64" AND NOT HAS_ARMV8_CRC)
284 set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -march=native")
285 endif()
286 endif()
287 endif()

修改了native 并新增了一行
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -march=loongarch64 -Os -Wall -s")
set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -Os -Wall -s")
修改为
else()
if(CMAKE_SYSTEM_PROCESSOR MATCHES "^s390x" AND NOT HAS_S390X_MARCH_NATIVE)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -march=z196")
elseif(NOT CMAKE_SYSTEM_PROCESSOR MATCHES "^(powerpc|ppc)64" AND NOT HAS_ARMV8_CRC)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -march=loongarch64 -Os -Wall -s")
set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -Os -Wall -s")
endif()
endif()
endif()

第四处配置文件为vim /data/servers/rocksdb-7.8.3/utilities/transactions/lock/range/range_tree/lib/portability/toku_time.h原配置#elif defined(__riscv) && __riscv_xlen == 32

uint32_t cycles_lo, cycles_hi0, cycles_hi1;
// Implemented in assembly because Clang insisted on branching.
asm volatile(
"rdcycleh %0\n"
"rdcycle %1\n"
"rdcycleh %2\n"
"sub %0, %0, %2\n"
"seqz %0, %0\n"
"sub %0, zero, %0\n"
"and %1, %1, %0\n"
: "=r"(cycles_hi0), "=r"(cycles_lo), "=r"(cycles_hi1));
return (static_cast<uint64_t>(cycles_hi1) << 32) | cycles_lo;

elif defined(__riscv) && __riscv_xlen == 64

uint64_t cycles;
asm volatile("rdcycle %0" : "=r"(cycles));
return cycles;

else

error No timer implementation for this platform

endif

}

新增配置#elif defined(loongarch)
struct timeval tv;
gettimeofday(&tv,NULL);
return tv.tv_sec*(uint64_t)1000000+tv.tv_usec;
完整如下

elif defined(__riscv) && __riscv_xlen == 32

uint32_t cycles_lo, cycles_hi0, cycles_hi1;
// Implemented in assembly because Clang insisted on branching.
asm volatile(
"rdcycleh %0\n"
"rdcycle %1\n"
"rdcycleh %2\n"
"sub %0, %0, %2\n"
"seqz %0, %0\n"
"sub %0, zero, %0\n"
"and %1, %1, %0\n"
: "=r"(cycles_hi0), "=r"(cycles_lo), "=r"(cycles_hi1));
return (static_cast<uint64_t>(cycles_hi1) << 32) | cycles_lo;

elif defined(__riscv) && __riscv_xlen == 64

uint64_t cycles;
asm volatile("rdcycle %0" : "=r"(cycles));
return cycles;

elif defined(loongarch)

struct timeval tv;
gettimeofday(&tv,NULL);
return tv.tv_sec*(uint64_t)1000000+tv.tv_usec;

else

error No timer implementation for this platform

endif

}
下载对应依赖 开始安装
yum -y install snappy-devel zstd-devel gflags-devel lz4-devel

编译安装rocksdb

cd /data/servers/rocksdb-7.8.3
mkdir build && cd build
cmake ..
make -j$(nproc)
make install

编译安装jni

cd /data/servers/rocksdb-7.8.3
PORTABLE=1 DEBUG_LEVEL=0 make -j8 rocksdbjava DISABLE_WARNING_AS_ERROR=1
安装完成之后
mkdir /data/servers/nacos/lib
cp /data/servers/rocksdb-7.8.3/java/target/librocksdbjni-linux64.so /data/servers/nacos/lib/librocksdbjni-linux64.so

启动服务

修改naocs启动脚本

/data/servers/nacos/bin/startup.sh

添加

!/bin/bash

export LD_LIBRARY_PATH=/data/servers/nacos/lib

启动nacos

cd /data/servers/nacos/nacos
[root@cn-loongarch64-195-11 bin]# cd bin/
[root@cn-loongarch64-195-11 bin]# ls
shutdown.cmd shutdown.sh startup.cmd startup.sh
[root@cn-loongarch64-195-11 bin]# ./startup.sh -m standalone
