当前机器上存在混合部署多套TiDB,所有会出现多个不同端口得进程
1.tidb-server
根据进程过滤，可以看到 tidb-server 启动时使用的参数以及配置文件tidb.toml
[tidb@ip-172-16-30-86 tidb-ansible]$ ps -ef|grep tidb-server
tidb 15642 10753 0 13:58 pts/2 00:00:00 grep --color=auto tidb-server

tidb 185764 185763 1 Mar01 ? 01:14:08 bin/tidb-server -P 5000 --status=10086 --advertise-address=172.16.30.86 --path=172.16.30.86:2479,172.16.30.87:2479,172.16.30.88:2479 --config=conf/tidb.toml --enable-binlog --log-file=/data/tidb/deploy_tidb/tidb/log/tidb.log
tidb-server 具体参数
官方文档链接：https://pingcap.com/docs-cn/op-guide/configuration/
[tidb@ip-172-16-30-86 bin]$ pwd
/data/tidb/deploy_tidb/tidb/bin
[tidb@ip-172-16-30-86 bin]$ ./tidb-server --help
Usage of ./bin/tidb-server:
-L string
log level: info, debug, warn, error, fatal (default "info")
-P string
# tidb server port (default "4000") tidb-server 的端口，默认为 4000

-advertise-address string
# tidb server advertise IP
-config string
# config file path，tidb 服务的配置文件，命令行的优先级高于配置文件
-enable-binlog
# enable generate binlog (default false)，是否开启 binlog，默认为关闭，若开启，则 ps -ef 时，tidb-server 后面就会跟上该参数，即 -enable-binlog
-host string
# tidb server host (default "0.0.0.0")
-lease string
# Schema 的 lease 主要用在 online schema changes 上面。这个值会影响到实际的 DDL 语句的执行时间。大多数情况下，用户不需要修改这个值
-log-file string
# log file path 日志的路径
-log-slow-query string
# slow query file path 慢日志的路径
-metrics-addr string
# prometheus pushgateway address, leaves it empty will disable prometheus push.prometheus push gateway 的地址，如果为空则不推送
-metrics-interval uint
# prometheus client push interval in second, set "0" to disable prometheus push. (default 15) 推送统计信息到 prometheus push Gateway 的时间间隔
-path string
# tidb storage path (default "/tmp/tidb") tidb 存储引擎的路径
-proxy-protocol-header-timeout uint
# proxy protocol header read timeout, unit is second. (default 5)。PROXY Protocol 请求头读取超时时间。
-proxy-protocol-networks string
# PROXY Protocol 允许的代理服务器地址列表，如果需要配置多个地址用,分隔。
-report-status
# If enable status report HTTP service. (default true) 打开或者关闭服务状态监听端口
-run-ddl
# run ddl worker on this tidb-server (default true) tidb-server 本身是否运行 ddl
-socket string
# The socket file to use for connection. 提供连接的 socket 文件
-status string
# tidb server status port (default "10080") tidb server 的状态端口
-store string
# registered store name, [tikv, mocktikv] (default "mocktikv")，tidb 底层使用搞得存储引擎
-token-limit int
# the limit of concurrent executed sessions (default 1000) TiDB 中允许同时运行的 session 数量，用于控制并发
部署前未配置ansible目录下conf/tidb.yml，则ansible部署按默认配置生成tidb.toml并启动

2.tikv-server
根据当前 tikv 启动进程状态，可以了解一些启动参数，注意：ps -ef|grep tikv-server 命令需要在安装tikv实例得机器上执行
[tidb@ip-172-16-30-88 ~]$ ps -ef|grep tikv-server

[tidb@ip-172-16-30-88 tikv2]$
查看 pd-server 的 help 的相关命令
[tidb@ip-172-16-30-88 tikv2]$ cd ..
[tidb@ip-172-16-30-88 deploy_tidb]$ cd pd/
[tidb@ip-172-16-30-88 pd]$ ls
backup bin conf data.pd log scripts status
[tidb@ip-172-16-30-88 pd]$ bin/pd-server --help
Usage of pd:
-L string
log level: debug, info, warn, error, fatal (default 'info') # pd server 输出日志格式
-V print version information and exit # pd server 版本
-advertise-client-urls string # pd server 本机客户端url 如：http://IP：2379，默认${client-urls}
advertise url for client traffic (default '${client-urls}')
-advertise-peer-urls string # pd server 其他节点客户端url 如：http://IP：2379，默认${peer-urls}
advertise url for peer traffic (default '${peer-urls}')
-cacert string # TLS 认证
Path of file that contains list of trusted TLS CAs
-cert string # PEM format
Path of file that contains X509 certificate in PEM format
-client-urls string # pd server 本机客户端url 如：http://IP：2379
url for client traffic (default "http://127.0.0.1:2379")
-config string # pd server 配置文件conf/pd.toml
Config file
-data-dir string # pd server 数据存放目录
path to the data directory (default 'default.${name}')
-initial-cluster string # 初始化 PD 集群配置。
initial cluster configuration for bootstrapping, e,g. pd=http://127.0.0.1:2380 默认: “{name}=http://{advertise-peer-url}”
例如，如果 name 是 “pd”, 并且 advertise-peer-urls 是 “http://192.168.100.113:2380", 那么 initial-cluster 就是 pd=http://192.168.100.113:2380
如果你需要启动三台 PD，那么 initial-cluster 可能就是 pd1=http://192.168.100.113:2380, pd2=http://192.168.100.114:2380, pd3=192.168.100.115:2380
-join string # 动态加入 PD 集群
默认: “”
如果你想动态将一台 PD 加入集群，你可以使用 --join="${advertise-client-urls}"， advertise-client-url 是当前集群里面任意 PD 的 advertise-client-url，你也可以使用多个 PD 的，需要用逗号分隔
join to an existing cluster (usage: cluster's '${advertise-client-urls}'
-key string
Path of file that contains X509 key in PEM format
-log-file string # 日志文件路径
log file path
-log-rotate # 日志文件是否开启切割
rotate log (default true)
-name string # pd 名字
human-readable name for this pd member (default "pd")
-namespace-classifier string
namespace classifier (default 'table') (default "table")
-peer-urls string
url for peer traffic (default "http://127.0.0.1:2380")
-version
print version information and exit
部署前未配置ansible目录下conf/pd.yml，则ansible部署按默认配置生成pd.toml并启动
