nginx环境：

nginx编译+配置环境 (opens new window)

# 下载
wget http://nginx.org/download/nginx-1.24.0.tar.gz
# 解压
tar -zxvf nginx-1.24.0.tar.gz
# 进入到源码目录
cd nginx-1.24.0/
cp -r contrib/vim/* ~/.vim # vim工具，高亮配置文件


# 查看configure 支持的参数，其中包含指定某些路径、开启某些模块、编译中特殊参数
#./configure --help | more
# 安装nginx必备依赖库
yum -y install gcc pcre pcre-devel zlib zlib-devel openssl openssl-devel
# 进行编译，指定安装目录，没什么报错就是编译成功
./configure --prefix=/nginx  --with-debug
make 
make install 

yum install -y pcre pcre-devel

yum install -y zlib zlib-devel

yum install -y openssl openssl-devel

yum install gcc-c++

yum -y install lua*

yum install -y wget

调试

• gdb关联进程调试时出现ptrace: Operation not permitted.

# 设置容器的privileged权限
docker exec --privileged -it build-pg /bin/bash 
# 设置允许非PTRACE权限的进程使用ptrace系统调用来追踪其他进程
echo 0 > /proc/sys/kernel/yama/ptrace_scope # 系统和容器的值都要修改

• ./configure --prefix=/nginx --with-debug

./objs/Makefile 下修改 增加-g （不确定是否需要）

ps -ef | grep nginx 查看工作线程和主线程（e为显示所有进程，f为全格式显示）

• 为了方便调试，关闭主线程，只有一个工作线程

vim [nginx的安装目录]/conf/nginx.conf

添加master_process off; # 关闭主线程，只有一个工作线程

添加daemon off # 关闭守护进程，前台工作

• b ngx_event.c:ngx_process_events_and_timers
