Linux安装nginx

centos 7.0根目录 的目录构成

[root@localhost src]# wget http://nginx.org/download/nginx-1.7.9.tar.gz --2015-01-24 12:55:21--  http://nginx.org/download/nginx-1.7.9.tar.gz 正在解析主机 nginx.org (nginx.org)... 206.251.255.63正在连接 nginx.org (nginx.org)|206.251.255.63|:80... 已连接。已发出 HTTP 请求，正在等待回应... 200 OK长度：827263 (808K) [application/octet-stream]正在保存至: “nginx-1.7.9.tar.gz”100%[======================================>] 827,263      154KB/s 用时 6.5s2015-01-24 12:55:28 (125 KB/s) - 已保存 “nginx-1.7.9.tar.gz” [827263/827263])[root@localhost src]# lsnginx-1.7.9.tar.gz

解压压缩包 .tar.gz解压压缩包 到指定的目录

[root@localhost src]# tar zxvf nginx-1.7.9.tar.gz -C /usr/local/bin

结果查看[root@localhost src]# cd /usr/local/bin[root@localhost bin]# lsnginx-1.7.9进入解压目录查看文件>文件>安装gcc

[root@localhost nginx-1.7.9]# yum -y install gcc-c++

安装最基础的模块 pcre-devel

[root@localhost nginx-1.7.9]# yum -y install pcre-devel

安装gzip

zlib-devel

[root@localhost nginx-1.7.9]# yum -y install zlib-devel

下面开始编译nginx 最简单 最少的编辑

[root@localhost nginx-1.7.9]# ./configure --prefix=/usr/etc/ngin

make

[root@localhost nginx-1.7.9]# make

make install

[root@localhost nginx-1.7.9]# make install

启动nginx

[root@localhost nginx-1.7.9]# cd /usr/etc[root@localhost etc]# lsngin[root@localhost etc]# cd ngin[root@localhost ngin]# lsconf  html  logs  sbin[root@localhost ngin]# cd sbin[root@localhost sbin]# lsnginx[root@localhost sbin]# ./nginx

查看进程 查看nginx是否启用

[root@localhost sbin]# ps -ef|grep nginxroot     13536     1  0 14:14 ?        00:00:00 nginx: master process ./nginxnobody   13537 13536  0 14:14 ?        00:00:00 nginx: worker processroot     13540  2281  0 14:16 pts/0    00:00:00 grep --color=auto nginx

lsof -i:80 安装root用户的才是 默认的nobody需要删除

[root@localhost sbin]# lsof -i:80COMMAND   PID   USER   FD   TYPE DEVICE SIZE/OFF NODE NAMEnginx   13536   root    6u  IPv4  32434      0t0  TCP *:http (LISTEN)nginx   13548 nobody    6u  IPv4  32434      0t0  TCP *:http (LISTEN)

重启nginx

[root@localhost sbin]# ./nginx -s reload

查看iptables表的规则 是否限制了80等、

[root@localhost sbin]# iptables -nL --line-numberChain INPUT (policy ACCEPT)num  target     prot opt source               destination1    ACCEPT     all  --  0.0.0.0/0            0.0.0.0/0            ctstate RELATED,ESTABLISHED2    ACCEPT     all  --  0.0.0.0/0            0.0.0.0/03    INPUT_direct  all  --  0.0.0.0/0            0.0.0.0/04    INPUT_ZONES_SOURCE  all  --  0.0.0.0/0            0.0.0.0/05    INPUT_ZONES  all  --  0.0.0.0/0            0.0.0.0/06    ACCEPT     icmp --  0.0.0.0/0            0.0.0.0/07    REJECT     all  --  0.0.0.0/0            0.0.0.0/0            reject-with icmp-host-prohibitedChain FORWARD (policy ACCEPT)num  target     prot opt source               destination1    ACCEPT     all  --  0.0.0.0/0            0.0.0.0/0            ctstate RELATED,ESTABLISHED2    ACCEPT     all  --  0.0.0.0/0            0.0.0.0/03    FORWARD_direct  all  --  0.0.0.0/0            0.0.0.0/04    FORWARD_IN_ZONES_SOURCE  all  --  0.0.0.0/0            0.0.0.0/05    FORWARD_IN_ZONES  all  --  0.0.0.0/0            0.0.0.0/06    FORWARD_OUT_ZONES_SOURCE  all  --  0.0.0.0/0            0.0.0.0/07    FORWARD_OUT_ZONES  all  --  0.0.0.0/0            0.0.0.0/08    ACCEPT     icmp --  0.0.0.0/0            0.0.0.0/09    REJECT     all  --  0.0.0.0/0            0.0.0.0/0            reject-with icmp-host-prohibitedChain OUTPUT (policy ACCEPT)num  target     prot opt source               destination1    OUTPUT_direct  all  --  0.0.0.0/0            0.0.0.0/0Chain FORWARD_IN_ZONES (1 references)num  target     prot opt source               destination1    FWDI_public  all  --  0.0.0.0/0            0.0.0.0/0           [goto]2    FWDI_public  all  --  0.0.0.0/0            0.0.0.0/0           [goto]Chain FORWARD_IN_ZONES_SOURCE (1 references)num  target     prot opt source               destinationChain FORWARD_OUT_ZONES (1 references)num  target     prot opt source               destination1    FWDO_public  all  --  0.0.0.0/0            0.0.0.0/0           [goto]2    FWDO_public  all  --  0.0.0.0/0            0.0.0.0/0           [goto]Chain FORWARD_OUT_ZONES_SOURCE (1 references)num  target     prot opt source               destinationChain FORWARD_direct (1 references)num  target     prot opt source               destinationChain FWDI_public (2 references)num  target     prot opt source               destination1    FWDI_public_log  all  --  0.0.0.0/0            0.0.0.0/02    FWDI_public_deny  all  --  0.0.0.0/0            0.0.0.0/03    FWDI_public_allow  all  --  0.0.0.0/0            0.0.0.0/0Chain FWDI_public_allow (1 references)num  target     prot opt source               destinationChain FWDI_public_deny (1 references)num  target     prot opt source               destinationChain FWDI_public_log (1 references)num  target     prot opt source               destinationChain FWDO_public (2 references)num  target     prot opt source               destination1    FWDO_public_log  all  --  0.0.0.0/0            0.0.0.0/02    FWDO_public_deny  all  --  0.0.0.0/0            0.0.0.0/03    FWDO_public_allow  all  --  0.0.0.0/0            0.0.0.0/0Chain FWDO_public_allow (1 references)num  target     prot opt source               destinationChain FWDO_public_deny (1 references)num  target     prot opt source               destinationChain FWDO_public_log (1 references)num  target     prot opt source               destinationChain INPUT_ZONES (1 references)num  target     prot opt source               destination1    IN_public  all  --  0.0.0.0/0            0.0.0.0/0           [goto]2    IN_public  all  --  0.0.0.0/0            0.0.0.0/0           [goto]Chain INPUT_ZONES_SOURCE (1 references)num  target     prot opt source               destinationChain INPUT_direct (1 references)num  target     prot opt source               destinationChain IN_public (2 references)num  target     prot opt source               destination1    IN_public_log  all  --  0.0.0.0/0            0.0.0.0/02    IN_public_deny  all  --  0.0.0.0/0            0.0.0.0/03    IN_public_allow  all  --  0.0.0.0/0            0.0.0.0/0Chain IN_public_allow (1 references)num  target     prot opt source               destination1    ACCEPT     tcp  --  0.0.0.0/0            0.0.0.0/0            tcp dpt:22 ctstate NEWChain IN_public_deny (1 references)num  target     prot opt source               destinationChain IN_public_log (1 references)num  target     prot opt source               destinationChain OUTPUT_direct (1 references)num  target     prot opt source               destination

查看规则

iptables -nL --line-number

iptables -nvL --line-number-L 查看当前表的所有规则，默认查看的是filter表，如果要查看NAT表，可以加上-t NAT参数-n 不对ip地址进行查，加上这个参数显示速度会快很多-v 输出详细信息，包含通过该规则的数据包数量，总字节数及相应的网络接口–line-number 显示规则的序列号，这个参数在删除或修改规则时会用到

现在访问http://192.168.1.103/ 无法访问 不知道什么情况额~ IP 肯定没错啊

后记：

查询一个包是否被安装# rpm -q < rpm package name>列出所有被安装的rpm package# rpm -qa

[root@localhost sbin]# rpm -qa

lsof 安装 查询端口启用情况 可以查询 nginx是否启用具体使用

最后的最后 居然是防火墙的问题 CentOS 7.0默认使用的是firewall作为防火墙关闭防火墙 systemctl stop firewalld.service #停止firewall在IP 访问一切正常systemctl disable firewalld.service #禁止firewall开机启动

[root@localhost init.d]# systemctl start firewalld.service 开启防火墙firewall[root@localhost init.d]# firewall-cmd --state  查看防火墙firewall运行状态running

启动后增加端口 通过规则

[root@localhost init.d]# firewall-cmd --add-port=80/tcpsuccess

再次访问 http://192.168.1.103/ 正常查看firewall 运行情况[root@localhost init.d]# firewall-cmd --statenot running参考文章firewall防火墙的介绍 上面的 添加端口 也是这里看到的~ http://linoxide.com/firewall/firewalld-centos-rhel/?utm_source=tuicool
