2.安装Nginx localhost:/etc/sysconfig/network # zypper search nginx Loading repository data... Reading installed packages... S | Name | Summary | Type ----------------------------------------------------------------------------------------- | dehydrated-nginx | Nginx Integration for dehydrated | package | nginx | A HTTP server and IMAP/POP3 proxy server | package | nginx-macros | Just some macros to make packaging nginx and modules easier | package | nginx-source | The nginx source | package
Note: For an extended search including not yet activated remote resources please use zypper search-packages. #安装 localhost:/etc/sysconfig/network # zypper in nginx Loading repository data... Reading installed packages... Resolving package dependencies...

localhost:/etc/sysconfig/network # firewall-cmd --add-port80/tcp --permanent localhost:/etc/sysconfig/network # firewall-cmd --reload 设置了也没有用原因不在这儿。 #查看错误日志 localhost:/etc/nginx # cat /var/log/nginx/error.log 2024/06/13 13:47:16 [error] 1453#1453: *4 open() /srv/www/htdocs/index.html failed (2: No such file or directory), client: 192.168.10.8, server: localhost, request: GET /index.html HTTP/1.1, host: 192.168.10.39 http://192.168.0.39/index.html 2024/06/13 13:56:43 [error] 2376#2376: *1 directory index of /srv/www/htdocs/ is forbidden, client: 192.168.10.8, server: localhost, request: GET / HTTP/1.1, host: 192.168.10.39 2024/06/13 13:56:47 [error] 2376#2376: *1 directory index of /srv/www/htdocs/ is forbidden, client: 192.168.10.8, server: localhost, request: GET / HTTP/1.1, host: 192.168.10.39 2024/06/13 13:57:00 [error] 2376#2376: *1 directory index of /srv/www/htdocs/ is forbidden, client: 192.168.10.8, server: localhost, request: GET / HTTP/1.1, host: 192.168.10.39 里面空空荡荡的使用SUSE库安装的和从Nginx下载的安装还是有点不同的。 localhost:~ # cd /srv/www/htdocs localhost:/srv/www/htdocs # ls 50x.html
3.配置Nginx 配置之前好好看了优化的相关文章优化的参数太多就修改了自己中意的几个。3.1配置参数优化Nginx vim /etc/nginx/nginx.conf worker_processes 8; worker_rlimit_nofile 65536; events { worker_connections 10240; use epoll; } --高效传输 sendfile on; tcp_nopush on;
--压缩 gzip on; gzip_min_length 1k; gzip_buffers 4 32k; gzip_comp_level 6; gzip_types text/plain application/x-javascript text/css application/xml text/javascript application/x-httpd-php image/jpeg image/gif image/png; gzip_vary off; gzip_disable MSIE [1-6]\.;
3.2文件句柄限制vim /etc/security/limits.conf * - nofile 65536 * soft nofile 65536 * hard nofile 65536 root soft nofile 65536 root hard nofile 65536
3.3内核参数优化vim /etc/sysctl.conf net.core.somaxconn 40960 fs.file-max 999999 --同时打开的最大句柄数 net.ipv4.tcp_tw_recycle 1--快速回收 net.ipv4.tcp_tw_reuse 1--开启重用 net.ipv4.tcp_syncookies 0--启用SYNC cookies net.ipv4.tcp_max_orphans 3276800
我的目的是让Nginx做请求代理服务器所以http配置如下 http { include mime.types; default_type application/octet-stream; log_format main $remote_addr - $remote_user [$time_local] $request $status $body_bytes_sent $http_referer $http_user_agent $http_x_forwarded_for; access_log /var/log/nginx/access.log main; sendfile on; tcp_nopush on; keepalive_timeout 65; gzip on; gzip_min_length 1k; gzip_buffers 4 32k; gzip_comp_level 6; gzip_types text/plain application/x-javascript text/css application/xml text/javascript application/x-httpd-php image/jpeg image/gif image/png; gzip_vary off; gzip_disable MSIE [1-6]\.; upstream srm { #sticky; ip_hash; server 192.168.10.1:82 weight3 max_fails2 fail_timeout36; server 192.168.10.2:82 weight3 max_fails2 fail_timeout36; server 192.168.10.3:82 weight3 max_fails2 fail_timeout36; server 192.168.10.4:82 weight3 max_fails2 fail_timeout36; } include conf.d/*.conf; server { listen 80; server_name localhost; #charset koi8-r; access_log /var/log/nginx/host.access.log main; location / { root /srv/www/htdocs/; index index.html index.htm; proxy_pass http://srm; proxy_set_header Host $host:80; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; client_max_body_size 100m; proxy_connect_timeout 15; proxy_read_timeout 300; proxy_send_timeout 500; if (-d $request_filename){ rewrite ^/(.*)([^/])$ /$1$2/ permanent; } }
4.防火墙设置允许端口 SuSEfirewall2配置简单但是将被 firewalld替代用yast2配置更直观一些。 #启停命令及状态查看 systemctl start firewalld systemctl enable firewalld systemctl stop firewalld systemctl disable firewalld firewall-cmd --state #查看安全域 localhost:/etc/sysconfig/network # firewall-cmd --get-zones localhost:/etc/sysconfig/network # firewall-cmd --get-default-zone #配置多个端口 localhost:/etc/sysconfig/network # firewall-cmd --add-port80/tcp --add-port22/tcp --permanent #配置服务 localhost:/etc/sysconfig/network #firewall-cmd --zonepublic --add-servicehttp #配置修改后重新加载 localhost:/etc/sysconfig/network #firewall-cmd --reload #列出安全域允许的服务 localhost:/etc/sysconfig/network #firewall-cmd --list-services --zonepublic #查看配置结果 localhost:/etc/sysconfig/network #firewall-cmd --list-all public (active) target: default icmp-block-inversion: no interfaces: eth0 sources: services: dhcpv6-client ssh ports: 80/tcp protocols: forward: no masquerade: no forward-ports: source-ports: icmp-blocks: rich rules:
5.升级Nginx失败 localhost:/etc/sysconfig/network # nginx -v nginx version: nginx/1.21.5 但是官网上的版本都已经1.27了继续往上升级 找到下载链接下载解压缩 localhost:/tmp #wget https://nginx.org/download/nginx-1.27.0.tar.gz localhost:/tmp #mkdir /usr/nginx localhost:/tmp #mv nginx-1.27.0.tar.gz /usr/nginx localhost://usr/nginx #tar -zxf nginx-1.27.0.tar.gz localhost:/usr/nginx #./configure make make install 结果获得错误 checking for C compiler ... not found ./configure: error: C compiler cc is not found localhost:/usr/nginx #whereis gcc 可以看到安装了gcc,怀疑版本问题 localhost:/usr/nginx #zypper install gcc 果然更新后检查通过但是遇到新问题了 ./configure error the HTTP rewrite module requires the PCRE library localhost:/usr/nginx #zypper install pcre 找不到安装包只能选择跳过 localhost:/usr/nginx #./confgure --without-http_rewrite_module make make install 又遇到新错误 ./configure error the HTTP Gzip module requires the zlib library 缺失那我就安装 localhost:/usr/nginx #zypper install zlib 可系统提示已经存在那就继续跳过 localhost:/usr/nginx #./configure --wirhout-http_rewrite_module --with-zlib/usr/share/man/mann/zbil.n.gz make make install 还是错误 fatal error:zlib.h:No such file or directory 算了还是老老实实用1.21.5版本。
