分享人：老牛

yum install screen -y && screen -S nginx

sudo yum -y groupinstall "Development Tools" && yum -y epel-release wget gc autoconf automake pcre-devel zlib-devel openssl-devel

----------------------yum安裝nginx(默認未編譯stream模塊,如果需要用按下面方法編譯)------------------------------

安裝nginx

sudo yum install nginx -y

設置nginx開機啟動

sudo systemctl enable nginx

-----------------------通過編譯安裝nginx(開啟stream模塊 動態加載方式)-----------------------------

編譯安裝nginx

sudo yum check-update || sudo yum update -y

yum groupinstall -y 'Development Tools'

yum install -y epel-release

yum install -y wget perl perl-devel perl-ExtUtils-Embed libxslt libxslt-devel libxml2 libxml2-devel gd gd-devel GeoIP GeoIP-devel

wget https://nginx.org/download/nginx-1.13.2.tar.gz && tar zxvf nginx-1.13.2.tar.gz

wget https://ftp.pcre.org/pub/pcre/pcre-8.40.tar.gz && tar xzvf pcre-8.40.tar.gz

wget https://www.zlib.net/zlib-1.2.11.tar.gz && tar xzvf zlib-1.2.11.tar.gz

wget https://www.openssl.org/source/openssl-1.1.0f.tar.gz && tar xzvf openssl-1.1.0f.tar.gz

rm -rf *.tar.gz

cd ~/nginx-1.13.2

cp ~/nginx-1.13.2/man/nginx.8 /usr/share/man/man8

gzip /usr/share/man/man8/nginx.8

man nginx

make

make install

ln -s /usr/lib64/nginx/modules /etc/nginx/modules

nginx -V

useradd --system --home /var/cache/nginx --shell /sbin/nologin --comment "nginx user" --user-group nginx

nginx -t

mkdir -p /var/cache/nginx && sudo nginx -t

vi /usr/lib/systemd/system/nginx.service

寫入以下內容

[Unit]

Description=nginx - high performance web server

Documentation=https://nginx.org/en/docs/

After=network-online.target remote-fs.target nss-lookup.target

Wants=network-online.target

[Service]

Type=forking

PIDFile=/var/run/nginx.pid

ExecStartPre=/usr/sbin/nginx -t -c /etc/nginx/nginx.conf

ExecStart=/usr/sbin/nginx -c /etc/nginx/nginx.conf

ExecReload=/bin/kill -s HUP $MAINPID

ExecStop=/bin/kill -s TERM $MAINPID

[Install]

WantedBy=multi-user.target

啟動nginx 設置開機啟動nginx

systemctl start nginx.service && sudo systemctl enable nginx.service

檢查nginx是否開機啟動

systemctl is-enabled nginx.service

檢查nginx是否正常運行

sudo systemctl status nginx.service

ps aux | grep nginx

curl -I 127.0.0.1

shutdown -r now

rm /etc/nginx/koi-utf /etc/nginx/koi-win /etc/nginx/win-utf

mkdir ~/.vim/

cp -r ~/nginx-1.13.2/contrib/vim/* ~/.vim/

rm /etc/nginx/*.default

-------------------------------nginx編譯安裝完畢------------------------------------------

-----------------------防火墻管理(未設置nginx 80端口可能無法訪問)-----------------------------

啟動防火墻

systemctl start firewalld.service

添加防火墻規則(添加80 443端口)--剛編譯的 若未添加 可能無法訪問

sudo firewall-cmd --permanent --zone=public --add-service=http

sudo firewall-cmd --permanent --zone=public --add-service=https

sudo firewall-cmd --reload

如需要可關閉防火墻

systemctl stop firewalld.service

關閉防火墻開機啟動

systemctl disable firewalld.service

設置防火墻開機啟動

systemctl enable firewalld.service

Centos7 防火墻 相關控制命令

systemctl is-enabled nginx.service #查詢nginx是否開機啟動

systemctl enable nginx.service #開機運行nginx

systemctl disable nginx.service #取消開機運行nginx

systemctl start nginx.service #啟動nginx

systemctl stop nginx.service #停止nginx

systemctl restart nginx.service #重啟nginx

systemctl reload nginx.service #重新加載nginx配置文件

systemctl status nginx.service #查詢nginx運行狀態

systemctl --failed #顯示啟動失敗的服務

#查看端口監聽情況

ss -tlnp|grep :80

nginx服務器默認root路徑

/usr/share/nginx/html

nginx服務器默認配置文件

/etc/nginx/nginx.conf

追加配置文件路徑(會自動加載.conf結尾的文件)

/etc/nginx/conf.d

---------------------------負載均衡配置------------------------------

清空nginx配置

cp /etc/nginx/nginx.conf /etc/nginx/nginx.confbackup

cat /dev/null > /etc/nginx/nginx.conf

vi /etc/nginx/nginx.conf

根據實際情況添加負載均衡配置

worker_processes 1;

load_module ?"modules/ngx_stream_module.so";

events {

worker_connections ?1024;

}

stream {

upstream backend {

hash $remote_addr consistent;

server 176.58.111.12:80 weight=5 max_fails=3 fail_timeout=30s;

server 178.79.163.35:80 weight=5 ?max_fails=3 fail_timeout=30s;

}

server {

listen 80;

proxy_connect_timeout 1s;

proxy_timeout 3s;

proxy_pass backend;

}

}
