nginx安装配置

nginx安装配置

最近部署项目用到了nginx,下面安装过程以及安装过程遇到的问题和解决方法

1.安装支持正则的pcre模块

shell:

tar zxvf pcre-8.02.tar.gz

cd pcre-8.02

./configure

make

make install

2.安装  gcc-c++（如果不存在)

yum install gcc-c++  

3.安装nginx

shell:

tar zxvf nginx-0.8.54.tar.gz

cd t ar zxvf  nginx-0.8.54

./configure --with-http_stub_status_module --with-http_gzip_static_module  --prefix=/opt/nginx

make

make install

ps: --prefix=/opt/nginx安装路径  --with-http_gzip_static_module传输压缩模块  --with-http_stub_status_module监控当前状态模块

ps:

CPU相关:

#user  nobody;

#worker_processes 4; 

进程位置

pid        logs/nginx.pid;

4.启动&停止

/opt/nginx/sbin/nginx -V    #查看编译选项，安装模块

/opt/nginx/sbin/nginx -t  #查看配置文件是否正确

/opt/nginx/sbin/nginx -t -c /opt/nginx/conf/nginx.conf  #指定配置文件是否正确

/opt/nginx/sbin/nginx  #启动

ps -ef|grep nginx  #查看pid

kill -XXX pid 

-XXX  : QUIT:请求处理完成后关闭进程

HUP:平滑重启

USR1,USR2

ps:其它关闭方法 /opt/nginx/sbin/nginx -s stop  # 详细 -h帮助

安装Nginx时报错 the HTTP cache module requires md5 functions

2011-09-25 13:20

安装Nginx时报错

./configure: error: the HTTP rewrite module requires the PCRE library.

安装pcre-devel解决问题
yum -y install pcre-devel

错误提示：./configure: error: the HTTP cache module requires md5 functions
from OpenSSL library.   You can either disable the module by using
--without-http-cache option, or install the OpenSSL library into the system,
or build the OpenSSL library statically from the source with nginx by using
--with-http_ssl_module --with-openssl=<path> options.

解决办法：

yum -y install openssl openssl-devel
