# CoMi Nginx安装和配置

Comi依赖Nginx反向代理，需要确保Comi和协同OA使用相同Nginx进行代理管理。

关于Nginx放置在哪个服务器可参考《CoMi环境准备指导手册 (opens new window)》中的服务器部署拓扑图，根据客户实际情况规划。

# Nginx安装

如客户环境没有Nginx，则参考《Nginx源码编译安装手册 (opens new window)》进行编译安装。

# Ngixn协同代理配置

Nginx部署后，首先参考《协同OA反向代理和负载均衡 (opens new window)》进行协同的代理配置，确保通过NG能访问协同系统之后，再进行CoMi的代理配置。

# Nginx代理CoMi配置

1、确保Nginx能代理访问协同后，再配置追加CoMi参数！

2、通过vim nginx.conf增加comi相关配置，仅需增加两块内容：

增加upstream统一管理AI-Manager地址
在协同OA的server块中增加include comi.conf;配置，让comi代理配置全部由comi.conf文件维护

comi start到comi end是增加的comi配置：

# comi start到comi end是增加的comi配置

# comi start：增加AI-Manager的upstream配置
upstream ai_manager{
    # 这里IP端口指向AI-manager地址
    server 192.168.0.171:8181;
}
# comi end：增加AI-Manager的upstream配置

# 代理协同OA
server {
    listen 80;
    server_name  localhost;
    charset utf-8;

    # comi start:关联comi配置文件
    include comi.conf;
    # comi end:关联comi配置文件

    location / {
        proxy_pass http://seeyon_v5_cluster;
        proxy_set_header Host $http_host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header REMOTE-HOST $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_redirect http:// $scheme://;
        proxy_connect_timeout 300;
        proxy_read_timeout 300;
        proxy_send_timeout 300;
    }
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   html;
    }
}

upstream seeyon_v5_cluster{
    sticky;
    server 192.168.0.170:8080 max_fails=300 fail_timeout=30s;
}

3、在nginx.conf同级目录下新建comi.conf（vim comi.conf命令），将如下配置完整保存到comi.conf（不用个性化调整任何参数）：

location ~ /\.(git|env|svn|htaccess|bak|old|swp)$ {
    deny all;
}
location /ai-static {
    proxy_set_header X-Real-Ip $remote_addr;
    proxy_set_header Host $http_host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_pass http://ai_manager;
    proxy_buffering off;
}

location = /seeyon/ai-platform/ai-manager/agent/info/call/sse {
    proxy_http_version 1.1;
    proxy_set_header Connection "";
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header Host $http_host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    # SSE 连接时的超时时间
    proxy_read_timeout 86400s;
    # 取消缓冲
    proxy_buffering off;
    # 关闭代理缓存
    proxy_cache off;
    rewrite ^/seeyon/ai-platform(.*)$ $1 break;
    proxy_pass http://ai_manager;
}
location = /seeyon/ai-platform/ai-manager/assistant/info/call/stream {
    proxy_http_version 1.1;
    proxy_set_header Connection "";
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header Host $http_host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    # SSE 连接时的超时时间
    proxy_read_timeout 86400s;
    # 取消缓冲
    proxy_buffering off;
    # 关闭代理缓存
    proxy_cache off;
    # 禁用分块传输编码
    chunked_transfer_encoding off;
    gzip off;
    rewrite ^/seeyon/ai-platform(.*)$ $1 break;
    proxy_pass http://ai_manager;
}

location ^~ /seeyon/ai-platform/backend {
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header Host $http_host;
    proxy_set_header X-Forwarded-Proto $scheme;
    rewrite ^/seeyon/ai-platform(.*)$ $1 break;
    proxy_pass http://ai_manager;
    set $nocache 1;
    proxy_cache_bypass $nocache $cookie_nocache $arg_nocache $arg_comment;
}
location ^~/seeyon/ai-platform/frontend {
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header Host $http_host;
    proxy_set_header X-Forwarded-Proto $scheme;
    rewrite ^/seeyon/ai-platform(.*)$ $1 break;
    proxy_pass http://ai_manager;
    set $nocache 1;
    proxy_cache_bypass $nocache $cookie_nocache $arg_nocache $arg_comment;
}
location ~ /seeyon/ai-platform {
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header Host $http_host;
    rewrite ^/seeyon/ai-platform(.*)$ $1 break;
    proxy_pass http://ai_manager;
}

location  ^~ /ai-manager {
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header Host $http_host;
    proxy_pass http://ai_manager;
}

4、检查配置并重新加载Nginx配置

# 检查配置是否正确（示例代码见截图）
./nginx -p nginx目录 -c nginx.conf配置文件路径 -t

# 重新加载配置，使配置生效（示例代码见截图）
./nginx -p nginx目录 -c nginx.conf配置文件路径 -s reload

# Nginx代理智能问数BI（按需）

如项目还需要使用智能问数功能，并且已经提前部署智能问数相关服务，则在Nginx增加如下配置即可使用：

1、通过vim nginx.conf增加智能问数bi相关配置，仅需增加两块内容：

增加upstream统一管理智能问数服务地址
在协同OA的server块中增加 include bi.conf; 配置，让bi代理配置全部由bi.conf文件维护

以下 bi start 到 bi end 是增加的智能问数BI配置：


# bi start：增加智能问数BI的upstream配置
upstream data_pulse{
    # 这里IP端口指向智能问数BI地址
    server 192.168.0.175:8058;
}
# bi end：增加智能问数BI的upstream配置

# 代理协同OA
server {
    listen 80;
    server_name  localhost;
    charset utf-8;

    include comi.conf;

    # bi start:关联bi配置文件
    include bi.conf;
    # bi end:关联bi配置文件

    location / {
        proxy_pass http://seeyon_v5_cluster;
        proxy_set_header Host $http_host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header REMOTE-HOST $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_redirect http:// $scheme://;
        proxy_connect_timeout 300;
        proxy_read_timeout 300;
        proxy_send_timeout 300;
    }
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   html;
    }
}

upstream seeyon_v5_cluster{
    sticky;
    server 192.168.0.170:8080 max_fails=300 fail_timeout=30s;
}

upstream ai_manager{
    server 192.168.0.171:8181;
}

2、在nginx.conf同级目录下新建名为bi.conf的文件（vim comi.conf命令），将如下配置完整保存到bi.conf（不用个性化调整任何参数）：

location /seeyon/bi/ {
    add_header 'Access-Control-Allow-Origin' '*';
    add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
    add_header 'Access-Control-Allow-Headers' 'Origin, Content-Type, Accept, Authorization';
    if ($request_method = 'OPTIONS') {
        add_header 'Access-Control-Allow-Headers' 'Origin, Content-Type, Accept, Authorization';
        add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
        add_header 'Access-Control-Allow-Origin' '*';
        return 204;
    }
    proxy_pass http://data_pulse/bi/;
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-Proto $scheme;
    proxy_cache_bypass $nocache $cookie_nocache $arg_nocache $arg_comment;
}

location /report {
    add_header 'Access-Control-Allow-Origin' '*';
    add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
    add_header 'Access-Control-Allow-Headers' 'Origin, Content-Type, Accept, Authorization';
    if ($request_method = 'OPTIONS') {
        add_header 'Access-Control-Allow-Headers' 'Origin, Content-Type, Accept, Authorization';
        add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
        add_header 'Access-Control-Allow-Origin' '*';
        return 204;
    }
    proxy_pass http://data_pulse/report;
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-Proto $scheme;
    proxy_cache_bypass $nocache $cookie_nocache $arg_nocache $arg_comment;
}


location /bi {
    add_header 'Access-Control-Allow-Origin' '*';
    add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
    add_header 'Access-Control-Allow-Headers' 'Origin, Content-Type, Accept, Authorization';
    if ($request_method = 'OPTIONS') {
        add_header 'Access-Control-Allow-Headers' 'Origin, Content-Type, Accept, Authorization';
        add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
        add_header 'Access-Control-Allow-Origin' '*';
        return 204;
    }
    proxy_pass http://data_pulse/bi;
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-Proto $scheme;
    proxy_cache_bypass $nocache $cookie_nocache $arg_nocache $arg_comment;
}

3、检查配置并重新加载Nginx配置

# 检查配置是否正确（示例代码见截图）
./nginx -p nginx目录 -c nginx.conf配置文件路径 -t

# 重新加载配置，使配置生效（示例代码见截图）
./nginx -p nginx目录 -c nginx.conf配置文件路径 -s reload
