nginx热更新实践

  1. 有的时候我们需要升级一下编译安装的nginx的版本
  2. 有的时候我们需要给编译安装的nginx上面添加一些扩展模块
  3. 有的时候，我们只是想玩玩。。。。

是的 ，这里都可以帮助你。。。

tar xf jemalloc-4.5.0.tar.bz2cd jemalloc-4.5.0 && ./configure && make && make install
apt-get install -y  lua5.1-0-dev# apt-get install -y libjemalloc-dev 如果上面没有编译安装jemalloc,可以使用apt进行安装groupadd www
useradd www

编译安装Nginx

编译安装1.10.3

tar xf nginx-1.10.3.tar.gz && cd nginx-1.10.3./configure --prefix=/webserver/nginx --user=www --group=www --with-pcre --with-zlib=/usr/local/src/zlib-1.2.8 --with-openssl=/usr/local/src/openssl-1.0.2d --with-http_gzip_static_module --with-http_realip_module --with-http_stub_status_module --add-module=/usr/local/src/ngx_devel_kit --add-module=/usr/local/src/lua-nginx-module --with-ld-opt=-ljemalloc --with-stream --with-http_ssl_module --add-module=/usr/local/src/nginx_upstream_check_module && make && make install

编译安装1.14.2

tar xf nginx-1.14.2.tar.gz && cd nginx-1.14.2./configure --prefix=/webserver/nginx14 --user=www --group=www --with-pcre --with-zlib=/usr/local/src/zlib-1.2.8 --with-openssl=/usr/local/src/openssl-1.0.2d --with-http_gzip_static_module --with-http_realip_module --with-http_stub_status_module --add-module=/usr/local/src/ngx_devel_kit --add-module=/usr/local/src/lua-nginx-module --with-ld-opt=-ljemalloc --with-stream --with-http_ssl_module --add-module=/usr/local/src/nginx_upstream_check_module && make && make install

nginx热升级

  1. 首先启动nginx1.10.3

  1. 备份nginx1.10.3的二进制文件
root@cluster-node1:/webserver/nginx/sbin# cp ./nginx ./nginx_1.10.3root@cluster-node1:/webserver/nginx/sbin# ls -ltotal 24840-rwxr-xr-x 1 root root 12715840 Aug  1 11:12 nginx

  1. 复制nginx 1.14.2版本的nginx二进制文件到当前的目录下覆盖nginx1.10.3的二进制文件
root@cluster-node1:/webserver/nginx/sbin# cp -f /webserver/nginx14/sbin/nginx ./root@cluster-node1:/webserver/nginx/sbin# ls -ltotal 25680-rwxr-xr-x 1 root root 13574704 Aug  1 11:31 nginx

  1. 下线旧版本的nginx的work进程

  1. 在退出nginx的时候，nginx旧版本的进程依旧存在，但是会在占用80端口，造成从新启动nginx失败，因此需要先杀掉80端口的旧版本的进程
