Nginx安装

1.1将资源上传到/home/diusr/tools/nginx目录下

1.2 离线安装GCC

进入gcc目录下进行命令执行

# 执行命令(安装离线包) rpm -Uvh *.rpm --nodeps --force

# 查询是否成功 gcc -v

1.3离线安装GCC-C++

进入gcc-c++目录下进行命令执行

# 执行命令(安装离线包) rpm -Uvh *.rpm --nodeps --force

# 查询是否成功 g++ -v

1.4安装pcre

# cd /home/diusr/tools/nginx

# tar -zxvf pcre-8.35.tar.gz

# cd pcre-8.35

# ./configure

# make

# make install

1.5安装 libtool

# cd /home/diusr/tools/nginx

# tar -zxvf libtool-2.4.2.tar.gz

# cd libtool-2.4.2

# ./configure

# make

# make install

1.6安装Nginx

# cd /home/diusr/tools/nginx

# tar -zxvf nginx-1.20.0.tar.gz

# cd nginx-1.20.0

# ./configure

# make

# make install

1.6.1启动Nginx（直接用默认配置启动测试即可）

# cd /usr/local/nginx/sbin

#./nginx

1.6.2开放端口(开放nginx默认使用的80端口，并重启防火墙)

# 开放80端口

firewall-cmd --zone=public --add-port=80/tcp --permanent

# 立即生效

# firewall-cmd --reload

1.6.3测试验证

1.6.4设置nginx开机自启

第一步---> 在/etc/systemd/system目录创建一个启动脚本

vim /etc/systemd/system/nginx.service

第二步---> 输入一下内容

[Unit]

Description=nginx service

After=network.target

[Service]

Type=forking

ExecStart=/usr/local/nginx/sbin/nginx

ExecReload=/usr/local/nginx/sbin/nginx -s reload

ExecStop=/usr/local/nginx/sbin/nginx -s quit

PrivateTmp=true

[Install]

WantedBy=multi-user.target

第三步---> 执行

# 查找nginx端口 ps -ef|grep nginx

# 先停止 nginx kill -9 xxx

# 执行 systemctl daemon-reload

# 开机自启 systemctl enable nginx

1.6.5 常用执行命令

# 启动nginx

systemctl start nginx

#设置开机自启动

systemctl enable nginx

#停止开机自启动

systemctl disable nginx

#查看服务当前状态

systemctl status nginx

#重新启动服务

systemctl restart nginx　

#查看所有已启动的服务

systemctl list-units --type=service

1.6.6 配置管理

# 修改nginx配置

vim /usr/local/nginx/conf/nginx.conf

#设定日志格式

#access_log off;

sendfile on;#以平衡磁盘与网络I/O处理速度，降低系统的负载。注意：如果图片显示不正常把这个改成off。默认开启状态

tcp_nopush on;#nginx在一个数据包里发送所有头文件，而不一个接一个的发送 ,防止网络阻塞

tcp_nodelay on;

#keepalive_timeout 0;

keepalive_timeout 60;#给客户端分配keep-alive链接超时时间。服务器将在这个超时时间过后关闭链接
