linux 下载 wget http://nginx.org/download/nginx-1.4.7.tar.gz 然后切换到nginx-1.4.7 检查 ./configure --prefix=/usr/local/nginx
报如下错
./configure: error: the HTTP rewrite module requires the PCRE library.
You can either disable the module by using --without-http_rewrite_module option, or install the PCRE library into the system, or build the PCRE library statically from the source with nginx by using --with-pcre=<path> option.
说明缺少 正则包 然后 yum install pcre 如果提示已经是最新的 那么 yum install pcre-devel
然后在 ./configure --prefix=/usr/local/nginx
如果再报错
./configure: error: the HTTP gzip module requires the zlib library.
You can either disable the module by using --without-http_gzip_module option, or install the zlib library into the system, or build the zlib library statically from the source with nginx by using --with-zlib=<path> option.
再 yum install -y zlib-devel 再 ./configure --prefix=/usr/local/nginx 出现下边的提示则说明成功
nginx path prefix: "/usr/local/nginx" nginx binary file: "/usr/local/nginx/sbin/nginx" nginx configuration prefix: "/usr/local/nginx/conf" nginx configuration file: "/usr/local/nginx/conf/nginx.conf" nginx pid file: "/usr/local/nginx/logs/nginx.pid" nginx error log file: "/usr/local/nginx/logs/error.log" nginx http access log file: "/usr/local/nginx/logs/access.log" nginx http client request body temporary files: "client_body_temp" nginx http proxy temporary files: "proxy_temp" nginx http fastcgi temporary files: "fastcgi_temp" nginx http uwsgi temporary files: "uwsgi_temp" nginx http scgi temporary files: "scgi_temp"
然后 make && make install
先说明一下nginx的主目录 conf 配置文件 html网页文件 logs 日志文件 sbin主要的二进制程序
然后启动nginx sbin目录下 ./nginx
出现 nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use) nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use) nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use) nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use) nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use) nginx: [emerg] still could not bind()
说明80端口有人在用
查看一下 netstat -antp
二.nginx信号量
查看 nginx的进程 ps aux|grep nginx 8998 是nginx的进程号
kill -int 8998 快速关闭
kill -quit 8998 优雅的关闭
kill -hup 8998 开启新进程,关闭旧进程
在配置文件修改后 可以使用 hup 重新开启即可
kill -usr1 8998 把旧的日志文件备份 添加新的日志文件后 就会把记录记录到新日志文件中
kill -usr2 8998
kill -winch 平滑升级用 winch配合usr2 升级用
