mac使用Homebrew安装开发工具 lcl

　　Homebrew 安装

/usr/bin/ruby -e "$(curl -fsSL https://cdn.jsdelivr.net/gh/ineo6/homebrew-install/install)"

一、安装OpenResty

　　安装并设置环境变量

brew install openresty/brew/openresty
export PATH=/usr/local/Cellar/openresty/1.19.9.1_2/nginx/sbin/:$PATH
nginx -v
mkdir -p devtools/nginx/seckillproject/conf
mkdir -p devtools/nginx/seckillproject/logs
cd devtools/nginx/seckillproject

　　配置文件内容

　　在conf目录中创建nginx.conf文件

vi conf/nginx.conf

　　添加配置

worker_processes  1;
error_log logs/error.log;
events {
    worker_connections 1024;
}
http {
    server {
        listen 8080;
        location / {
            default_type text/html;
            content_by_lua_block {
                ngx.say("<p>hello, world</p>")
            }
        }
    }
}

验证：启动nginx后，访问localhost:8080，可以访问即可。

# 启动
nginx -p `pwd`/ -c conf/nginx.conf
# 查看
ps -ef|grep nginx
# 停止
nginx -p pwd -s stop

　　　　　　

二、安装MySQL

　　安装并设置环境变量

brew install mysql@5.7
export PATH=/usr/local/opt/mysql@5.7/bin:$PATH

　　验证

mysql.server start
mysql_secure_installation
mysql -uroot -p
show databases;
mysql.server stop

三、安装redis

　　安装并验证

brew install redis
/usr/local/opt/redis/bin/redis-server /usr/local/etc/redis.conf
##另起一个窗口，使用客户端验证
redis-cli -h 127.0.0.1 -p 6379

 四、安装Nginx

# 安装
brew install nginx
# 启动
brew services start nginx
# 停止
brew services stop nginx
#重启nginx
brew services restart nginx
#重新加载配置文件
nginx -s reload
#验证nginx配置文件是否正确
nginx -t
#配置文件位置
/usr/local/etc/nginx/nginx.conf

 五、安装 jenv 管理多版本JDK

　　1、安装jenv

mkdir -p ~/.jenv/versions
brew install jenv
echo 'export PATH="$HOME/.jenv/bin:$PATH"' >> ~/.bash_profile
echo 'eval "$(jenv init -)"' >> ~/.bash_profile

　　2、将多版本JDK绑定到jenv

jenv add /Library/Java/JavaVirtualMachines/jdk-11.0.15.jdk/Contents/Home
jenv add /Library/Java/JavaVirtualMachines/jdk1.8.0_301.jdk/Contents/Home

　　3、查看当前试用版本（*号标记的为当前版本）

#  jenv versions
* system (set by /Users/conglongli/.jenv/version)
  1.8
  1.8.0.301
  11
  11.0
  11.0.15
  oracle64-1.8.0.301
  oracle64-11.0.15

　　4、切换版本

#  jenv local 1.8.0.301
#  jenv versions
  system
  1.8
* 1.8.0.301 (set by /Users/conglongli/.java-version)
  11
  11.0
  11.0.15
  oracle64-1.8.0.301
  oracle64-11.0.15

　　5、移除不需要的版本

#  jenv remove 11.0
JDK 11.0 removed

 六、安装wrk

brew install wrk
# 使用12个线程，创建400个连接，对baidu首页进行了30秒的压测，并要求在压测结果中输出响应延迟信息
conglongli@bogon ~ % wrk -t12 -c400 -d30s --latency http://www.baidu.com
