Nginx 安装
系统平台:CentOS7 64位。
安装编译工具及库文件
yum -y install gcc pcre-devel zlib-devel openssl openssl-devel
安装 Nginx
1、下载 Nginx,下载地址:https://nginx.org/download/
wget http://nginx.org/download/nginx-1.9.9.tar.gz
2、解压安装包
tar zxvf nginx-1.9.9.tar.gz
3、进入安装包目录
cd nginx-1.9.9
4、编译安装
./configure --prefix=/usr/local/nginx
make
make install
5、查看nginx版本
#cd /usr/local/nginx/sbin
./nginx -v
到此,nginx安装完成。
测试是否安装成功
# cd到刚才配置的安装目录/usr/loca/nginx/
./sbin/nginx -t
错误信息:
nginx: [alert] could not open error log file: open() "/usr/local/nginx/logs/error.log" failed (2: No such file or directory)
2016/09/13 19:08:56 [emerg] 6996#0: open() "/usr/local/nginx/logs/access.log" failed (2: No such file or directory)
原因分析:nginx/目录下没有logs文件夹
解决方法:
mkdir logs
chmod 700 logs
正常情况的信息输出:
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
启动nginx
cd /usr/local/nginx/sbin
./nginx //启动nginx
在浏览器中输入服务器的ip地址,如:192.168.1.12
很不幸,打不开链接。下面进行原因排查:
说明服务器的80端口是打不开的。
因为我使用的linux系统版本是CentOS7,所以可以在服务器中执行如下命令来验证》》
firewall-cmd --query-port=80/tcp
显然80端口没有开启。
下面我们开启80端口:
firewall-cmd --add-port=80/tcp --permanent
#重启防火墙
systemctl restart firewalld
--permanent #永久生效,没有此参数重启后失效
刷新浏览器
配置完毕!
配置nginx开机自启动
vim /etc/rc.d/rc.local
Nginx 配置
创建 Nginx 运行使用的用户 www:
[root@bogon conf]# /usr/sbin/groupadd www
[root@bogon conf]# /usr/sbin/useradd -g www www
配置nginx.conf ,将/usr/local/webserver/nginx/conf/nginx.conf替换为以下内容
[root@bogon conf]# cat /usr/local/webserver/nginx/conf/nginx.conf
user www www;
worker_processes 2; #设置值和CPU核心数一致
error_log /usr/local/webserver/nginx/logs/nginx_error.log crit; #日志位置和日志级别
pid /usr/local/webserver/nginx/nginx.pid;
#Specifies the value for maximum file descriptors that can be opened by this process.
worker_rlimit_nofile 65535;
events
{
use epoll;
worker_connections 65535;
}
http
{
include mime.types;
default_type application/octet-stream;

#下面是server虚拟主机的配置

fastcgi_pass 127.0.0.1:9000;

}

# access_log off;
}

}
}
检查配置文件nginx.conf的正确性命令:
[root@bogon conf]# /usr/local/nginx/sbin/nginx -t
启动 Nginx
Nginx 启动命令如下:
[root@bogon conf]# /usr/local/nginx/sbin/nginx
nginx版本过低先要安装 PCRE
PCRE 作用是让 Nginx 支持 Rewrite 功能。
1、下载 PCRE 安装包
下载地址: http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz
[root@bogon src]# cd /usr/local/src/
[root@bogon src]# wget http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz
2、解压安装包:
[root@bogon src]# tar zxvf pcre-8.35.tar.gz
3、进入安装包目录
[root@bogon src]# cd pcre-8.35
4、编译安装
[root@bogon pcre-8.35]# ./configure
[root@bogon pcre-8.35]# make && make install
5、查看pcre版本
[root@bogon pcre-8.35]# pcre-config --version
