CentOS linux安装nginx

1. 下载nginx-1.21.3.tar.gz 及 nginx-upstream-fair-master.zip

2. 上传nginx-upstream-fair-master至/app/server/nginx/modules/解压

cd /app/server/nginx/modules
unzip nginx-upstream-fair-master.zip

3. 上传nginx压缩包至**/app/server/nginx/ **（根据自己需求而定）

4. 切换路劲

cd /app/server/nginx

5. 解压

tar -zxvf nginx-1.21.3.tar.gz

6. 编辑/app/server/nginx/nginx-1.21.3/auto/lib/openssl/conf文件

cat /app/server/nginx/nginx-1.21.3/auto/lib/openssl/conf
vim /app/server/nginx/nginx-1.21.3/auto/lib/openssl/conf

将原数据

CORE_INCS="$CORE_INCS $OPENSSL/.openssl/include"
CORE_DEPS="$CORE_DEPS $OPENSSL/.openssl/include/openssl/ssl.h"
CORE_LIBS="$CORE_LIBS $OPENSSL/.openssl/lib/libssl.a"
CORE_LIBS="$CORE_LIBS $OPENSSL/.openssl/lib/libcrypto.a"

修改为：

CORE_INCS="$CORE_INCS $OPENSSL/include"
CORE_DEPS="$CORE_DEPS $OPENSSL/include/openssl/ssl.h"
CORE_LIBS="$CORE_LIBS $OPENSSL/lib64/libssl.a"
CORE_LIBS="$CORE_LIBS $OPENSSL/lib64/libcrypto.a"

7. 修改/app/server/nginx/nginx-1.21.3/src/http/ngx_http_upstream.h文件

新增一个default_port

struct ngx_http_upstream_srv_conf_s {
ngx_http_upstream_peer_t peer;
void **srv_conf;ngx_array_t *servers; /* ngx_http_upstream_server_t */ngx_uint_t flags;
ngx_str_t host;
u_char *file_name;
ngx_uint_t line;
in_port_t port;
in_port_t default_port; /* 新增一个default_port */
ngx_uint_t no_port; /* unsigned no_port:1 */#if (NGX_HTTP_UPSTREAM_ZONE)
ngx_shm_zone_t *shm_zone;
#endif
};

8. 切至nginx目录

cd /app/server/nginx/nginx-1.21.3

9. 配置

./configure --prefix=/app/server/nginx/nginx-all --with-http_stub_status_module --with-http_ssl_module --with-http_gzip_static_module --with-openssl=/usr/local/openssl3.0.0 --with-openssl-opt="enable-tlsext" --with-http_v2_module --add-module=/app/server/nginx/modules/nginx-upstream-fair-master

配置解释：

/app/server/nginx/nginx-all 是安装路径，不能安直接安装到解压路径
http_stub_status_module 监控模块
with-http_ssl_module ssl模块
http_gzip_static_module gzip模块
/usr/local/openssl3.0.0 openssl安装路径路径
nginx-upstream-fair-master 负载均衡模块
http_v2_module http2模块
提示./configure: error: the HTTP rewrite module requires the PCRE library.错误时，需要安装pcre-devel（命令：yum -y install pcre-devel）

10. 编译安装

make
make install
