安装nginx步奏如下
1.安装所需依赖
yum install -y gcc gcc-c++ pcre pcre-devel zlib zlib-devel openssl openssl-devel automake autoconf libtool make
2. 解压nginx压缩包，进入解压后的nginx目录
tar -xvf ./nginx-1.24.0.tar.gz
cd ./nginx
3. 以下编译命令中增加模块有，ssl支持 stream支持，需要其他的模块可以自行添加即可。这里配置安装目录为/usr/local/nginx
# 编译
./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-stream
# 安装
make && make install
- 进入安装目录
cd /usr/local/nginx
- 启动
./sbin/nginx -c ./conf/nginx.conf
- 常用命令
# 启动nginx
./sbin/nginx -c ./conf/nginx.conf
# 停止
./sbin/nginx -s stop
# 修改配置文件后重新加载配置文件
# 检测配置文件是否有错
./sbin/nginx -t
# 重新加载配置
./sbin/nginx -s reload
以上配置oracle代理时候可能会出现
unknown directive “stream” in /usr/local/nginx/conf/nginx.conf 报错
解决办法如下
进入nginx文件解压目录，进行编译、安装，通过添加–with-stream参数指定安装stream模块。
[root@localhost nginx-1.12.2]# ./configure --with-stream
[root@localhost nginx-1.12.2]# make & make install
再次检查nginx.conf配置文件，确认配置无语法错误后，再次尝试启动服务。
[root@localhost sbin]# ./nginx
安装oracle23 教程如下
1.1. docker pull container-registry.oracle.com/database/free:latest
2. mkdir -p /home/mymount/oracle23c/oradata
3. # 授权，不授权会导致后面安装失败
chmod 777 /home/mymount/oracle23c/oradata
4.3. #racle_SID是用来唯一标识一个Oracle实例的,确保了在同一台服务器上不存在SID冲突的情况,也方便了在多台服务器上进行数据库管理。
docker run -d \
-p 1522:1521 -p 5501:5500 \
-e ORACLE_PDB=PDB \
-e ORACLE_PWD=123456 \
-e ORACLE_EDITION=standard \
-e ORACLE_CHARACTERSET=AL32UTF8 \
-v /home/mymount/oracle23c/oradata:/opt/oracle/oradata \
--name oracle23 \
container-registry.oracle.com/database/free:latest
- 查看是否启动成功
docker logs -tf oracle23
6.进入容器
docker exec -it oracle23 bash
7.启动oracle
输入sqlplus 然后会提示你输入账号密码 或者直接输入
sqlplus / as sysdba
8.查询有哪些pdb库
select name,open_mode from v$pdbs;
9.然后切换到除了pdb开头的数据库
alter session set container=FREEPDB1;
10 .查找用户
select userName from dba_users;
11查看有哪些表空间
select tableSpace_name from Dba_tablespaces;
12 删除用户以及表结构(参照：https://blog.csdn.net/daxiang52/article/details/50408312)
drop user ZS_EDU cascade;
- 创建临时表空间
create temporary tablespace eduTem tempfile '/opt/oracle/oradata6' size 50m autoextend on next 50m maxsize 20480m extent management local;
14创建表空间（查看有哪些表空间select tableSpace_name from Dba_tablespaces;）
create tablespace edu logging datafile '/opt/oracle/oradata7' size 50m autoextend on next 50m maxsize 20480m extent management local;
17 删除表空间 Oracle删除表空间语法结构：（https://www.php.cn/faq/489137.html）
drop tablespace tab_name [including contents][cascade constraints]
案例、删除student表空间，并删除表空间的数据文件和完整性
drop tablespace student including contents cascade constraints;
- 创建用户并指定表空间
create user zs_edu identified by zsShang default tablespace edu temporary tablespace eduTem;
- 给用户授权
grant connect,resource,dba to 用户名;
以下场景适用于只开放了一个端口9003的情况下需要来回切换端口（以下为nginx配置代理oracle）

#error_log logs/error.log info;
