安装依赖
centos
# 如果已经存在不需要安装
yum install gcc gcc-c++
# 如果已经存在不需要安装
yum install make
yum install flex bison ncurses ncurses-devel
yum install -y gcc make bison openssl-devel pkgconfig mysql-devel libcurl-devel pcre-devel zlib-devel
yum install -y redis
ubuntu
# apt update
# apt install gcc -y
# apt install g++ -y
# apt install build-essential -y
//mysql必须为5.7版本，服务端已经装好docker，这里就不装了，若要安装，则安装下，要去配置文件中注释监听地址 # 127.0.0.1
// #apt-get install mysql-server
# apt install mysql-client
# apt install libmysqlclient-dev -y
# apt install pkg-config
# apt install libssl-dev

# apt-get install bison flex libncurses5 libncurses5-dev
下载
访问官网https://opensips.org/pub/opensips/latest/找最新版本
下载https://opensips.org/pub/opensips/latest/opensips-3.3.5.tar.gz
cd /usr/local/opensips
wget https://opensips.org/pub/opensips/2.4.11/opensips-2.4.11.tar.gz
# 解压
tar -zxvf opensips-2.4.11.tar.gz
# 切换目录
cd opensips-2.4.11
选择安装模块（db_mysql）
1、在opensips源码根目录执行make menuconfig，出现配置界面
2、箭头移动到“Configure Compile Options”，按右方向键→进入“Configure Excluded Modules”
3、移动到“db_mysql”项，按空格键选中，选中出现“*”号
数据库版本5.7
mysql8.0会提示mysql授权语句错误
配置安装目录
再按左方向键←回到上一页，移动到“Configure Install Prefix”，再按并按右方向键→，输入opensips安装目录为/usr/local/opensips/opensips2，回车保存。
默认位置：/usr/local/share/opensips/
默认启动项：/usr/local/sbin/下面
默认配置项：/usr/local/etc/opensips/
如果配置了Install Prefix，比如/usr/local/opensips/opensips2 则
位置：/usr/local/opensips/opensips2
启动项：/usr/local/opensips/opensips2/sbin/下面
认配置项：/usr/local/opensips/opensips2/etc/opensips/
保存配置项
再按左方向键←回到上一页，移动到“Save Changes ”，并按右方向键→，执行保存操作。
安装
回到上一页选择“Compile And Install OpenSIPS”，Enter执行编译。
配置日志
OpenSIPS实战（二）：日志文件配置
OpenSIPS可以设置写入的设施，设施配置对应的log文件路径。默认配置的是log_facility=LOG_LOCAL0。如下配置：
vim /etc/rsyslog.conf
# 增加一行：
local0.* /opt/opensips.log
# 一定要创建并授权
cd /opt
touch opensips.log
sudo chmod -R 777 /opt/opensips.log
# 然后重启rsyslog服务：
/etc/init.d/rsyslog restart #（如果删除了日志文件，也要再次执行这个命令才行）
需要注意的是只有opensips.cfg配置debug_mode=no及log_stderror=no时日志才会写文件。
配置数据库
cd /usr/local/etc/opensips/ # 或者自定义目录/usr/local/opensips/opensips2/etc/opensips
vim opensipsctlrc
修改如下：
创建opensips数据库
//进入文件夹
# cd /usr/local/sbin
//创建数据库，这时候如果mysql版本为8.0以上的话会列出一系列编码选择，得mysql5.7版本不会出现这问题
opensipsdbctl create # 或者 sudo ./opensipsdbctl create
//表创建完成后（提示的两个问题都选n）
执行完成之后发现有很多表
配置文件 opensips.cfg

生成特定配置文件
# 进入目录
cd /usr/local/etc/opensips
# osipsconfig
./osipsconfig
操作内容
//依次选择—> Generate OpenSIPS Script —> Residential Script —> Configure Residential Script
//选中如下几项[] ENABLE_TCP[] USE_AUTH[] USE_DBACC[] USE_DBUSRLOC[*] USE_DIALOG
//按q返回，选择 —> Generate Residential Script 回车，生成新的配置文件，文件格式为opensips_residential_xxxxx.cfg，按qqq退出命令，生成新的配置文件
备份旧文件，修改新文件
# 备份原配置文件
# mv opensips.cfg opensipsold.cfg1
# 用生成的opensips_residential_xxx.cfg替换原先的opensips.cfg：
mv opensips_residential_2021-7-21_6:35:0.cfg opensips.cfg
# 编辑新生成的配置文件,修改监听端口和ip,ip把127.0.0.1改为自己的ip，保存
vim opensips.cfg
注意如果自定义了安装路径，需要修改模块地址
mpath=“/usr/local/opensips/opensips2/lib64/opensips/modules/”
#mpath=“/usr/local//lib64/opensips/modules/”
修改数据库配置
创建用户
opensipsctl add 1000 123456 //创建账号1000 密码123456
opensipsctl add 1001 123456 //创建账号1001 密码123456
//创建账号将在表subscriber新增一条记录，也可以在数据库直接修改
启动
常用命令
cd /usr/local/sbin
sudo opensipsctl start 启动服务
sudo opensipsctl stop 停止服务
sudo opensipsctl restart 重启服务
查询在线用户
./opensipsctl online

常见错误
ERROR: database engine not specified, please setup one in the config script
是因为opensipsctlrc配置文件中没有设置mysql信息
