1 运行方案分析

三个方案运行yunzai：

trss，卡死，放弃
miao-yunzai 自带的docker-compose.yml，容器构建速度太慢，放弃
直接用npm安装nodejs运行，可行。

环境：CentOS7.9，下载 Miao-yunzai项目

# 使用Gitee
git clone --depth=1 https://gitee.com/yoimiya-kokomi/Miao-Yunzai.git
cd Miao-Yunzai 
git clone --depth=1 https://gitee.com/yoimiya-kokomi/miao-plugin.git ./plugins/miao-plugin/

3 排错

参考： https://github.com/TryGhost/node-sqlite3/issues/1582#issuecomment-1198949710 解决：

下载gcc10-libstdc++，来源： https://mirror.ghettoforge.org/distributions/gf/el/7/gf/x86_64/
安装 rpm -i gcc10-libstdc++-10.2.1-7.gf.el7.x86_64.rpm, 此时 /opt/会多出一个gcc10目录
设置环境变量并运行miao-yunzai LD_LIBRARY_PATH=$PATH:/opt/gcc-10.2.1/usr/lib64/ node app

终于可以成功登录，再次运行：发现puppeteer响应速度超过40秒，以至于几乎无法使用。

4 优化1：给系统添加swap分区

参考： https://www.digitalocean.com/community/tutorials/how-to-add-swap-on-centos-7

查看系统是否存在分区

1
free -m

显然没有

1
2
3
4
             total       used       free     shared    buffers     cached
Mem:          3953        315       3637          8         11        107
-/+ buffers/cache:        196       3756
Swap:            0          0       4095

4.1 创建swap分区

2G有多了

1
sudo dd if=/dev/zero of=/swapfile count=2048 bs=1MiB

4.2 启用swap

1
sudo chmod 600 /swapfile

1
sudo mkswap /swapfile

1
sudo swapon /swapfile

查看swap

1
swapon -s

1
2
3
[root@localhost ]# swapon -s
Filename				Type		Size	Used	Priority
/swapfile                              	file	3145724	40556	-2

4
[root@localhost ]# free -h
              total        used        free      shared  buff/cache   available
Mem:           447M         93M         50M         44K        303M        342M
Swap:          3.0G         0M        3.0G

4.3 持久化swap

1
vim /etc/fstab

添加以下内容到fstab底部

1
/swapfile   swap    swap    sw  0   0

4.4 调整swap调度策略

1
2
cat /proc/sys/vm/swappiness
0

调整为0以上，否则puppeteer可能不适用交换内存，我直接设置为100

1
sudo sysctl vm.swappiness=100

系统文件也改一下

1
vim /etc/sysctl.conf

1
vm.swappiness = 100

5 优化2：使用自定义chromium

5.1 安装chromium-headless

1
yum install chromium-headless

假如报错：No package chromium-headless available. Error: Nothing to do
解决： yum安装出现No package ****** available-CSDN博客

1
2
3
4
yum intsall epel-release
yum clean all
yum update
yum makecache

查看chromium-headless安装位置

1
/usr/lib64/chromium-browser/headless_shell

5.2 安装puppeteer-core

由于不再使用puppeteer自带的chrome，我们把puppeteer库该为puppeteer-core 进入Miao-yunzai项目根目录，修改package.json

1
vim package.json

添加依赖

1
 "puppeteer-core": "^21.5.2",

安装依赖

1
pnpm install -P

修改渲染器代码

1
vim renderers/puppeteer/lib/puppeteer.js

修改导入的包

1
2
# import puppeteer from 'puppeteer'
import puppeteer from 'puppeteer-core'

5.3 修改启动参数，指定chromium的位置

    this.config = {
      headless: 'new', //Data.def(config.headless, true),
      executablePath: '/usr/lib64/chromium-browser/headless_shell',
      args: Data.def(config.args, [
        '--disable-gpu',
        '--disable-setuid-sandbox',
        '--no-sandbox',
        '--no-zygote'
      ])

5.4 乱码解决

1
yum groupinstall fonts -y

5.5 执行更新操作时候报错

https://computingforgeeks.com/install-git-2-on-centos-7/ 装最新版git

5.6 重启启动miao-yunzai

1
LD_LIBRARY_PATH=$PATH:/opt/gcc-10.2.1/usr/lib64/ node app
