Linux 安装nginx

1、检测所需扩展是否都已安装：

rpm -qa | grep "pcre"
rpm -qa | grep "openssl"
rpm -qa | grep "wget"
rpm -qa | grep "zlib"

# 如果缺少某一扩展 用yum安装即可
yum install pcre* -y
yum install openssl* -y
yum install zlib -y
yum install zlib-devel -y

2、下载nginx安装包：

wget http://nginx.org/download/nginx-1.8.0.tar.gz

3、解压：

tar -zxvf nginx-1.8.0.tar.gz

4、安装：

cd nginx-1.8.0
./configure --prefix=/usr/local/nginx --error-log-path=/var/log/nginx/error.log 
--pid-path=/var/run/nginx.pid --lock-path=/var/lock/nginx --user=www --group=www 
--without-select_module --without-poll_module --with-file-aio --with-http_ssl_module 
--with-http_realip_module --with-http_stub_status_module --without-http_ssi_module 
--without-http_userid_module --without-http_uwsgi_module --without-http_scgi_module 
--without-http_memcached_module --without-http_limit_conn_module 
--without-http_limit_req_module --http-log-path=/var/log/nginx/access.log 
--http-client-body-temp-path=/tmp/client-body-temp --http-proxy-temp-path=/tmp/proxy-temp 
--http-fastcgi-temp-path=/tmp/fastcgi-temp --without-mail_pop3_module --without-mail_imap_module 
--without-mail_smtp_module --add-module=../agentzh-headers-more-nginx-module-*/

make && make install 

5、启动：

cd /usr/local/nginx/sbin
./nginx

# 重新载入配置文件
./nginx -s reload

6、添加到service 服务中：

# 首先在/usr/bin 目录下创建nginx 软连
cd /usr/bin
ln -s /usr/local/nginx/sbin/nginx nginx

# 编写nginx 启动shell 脚本 
cd /etc/init.d
vim nginx

# 代码在下方

nginx 启动代码：

#!/bin/bash

# 添加可执行权限
chmod +x nginx 
service nginx start
