Nginx

 

 

 

安装Nginx

---

 安装依赖

yum install -y gcc gcc-c++ make zlib zlib-devel openssl openssl-devel

创建nignx用户和组，用来启动nginx

groupadd nginx -g 555
useradd -g nginx -u 555 -M -s /sbin/nologin nginx

建议：如果nginx做集群，两台nginx的uid和组id最好一致.

安装pcre

让nignx支持rewrite

cd /usr/local/src
curl -O https://nchc.dl.sourceforge.net/project/pcre/pcre/8.40/pcre-8.40.tar.gz
tar xf pcre-8.40.tar.gz
cd pcre-8.40
./configure
make
make install

编译安装nginx

curl -O  http://nginx.org/download/nginx-1.12.0.tar.gz
tar xf nginx-1.12.0.tar.gz
cd nginx-1.12.0
./configure --prefix=/usr/local/nginx \
--user=nginx \
--group=nginx \
--with-http_gzip_static_module \
--with-http_ssl_module \
--with-http_stub_status_module \
--with-pcre=/usr/local/src/pcre-8.40 \
--with-stream
make -j2
make install

创建软连接(可选)

ln -s /usr/local/nginx/sbin/nginx /usr/local/bin

添加启动脚本

#!/bin/sh
#
# nginx - this script starts and stops the nginx daemon
#
# chkconfig:   - 85 15

esac

cp nginx.init /etc/init.d/nginx
chmod +x /etc/init.d/nginx
chkconfig --add nginx
chkconfig nginx --level 35 on
service nginx start

其它配置

mkdir /usr/local/nginx/vhost         # 创建虚拟机主机、upstream的配置目录
mkdir /data/html -p                  # 创建网站的数据目录
mkdir /data/logs/nginx -p            # 创建nginx的日志目录
