ubuntu网络、包管理、工作内容小结

中国地图

1.配置IP

cat /etc/network/interfaces
auto lo
iface lo inet loopback

# The loopback network interface
auto enp6s0f0
iface enp6s0f0 inet static
pre-up ifconfig enp6s0f0 hw ether 00:23:81:26:73:31
address 192.168.166.45
netmask 255.255.255.0
gateway 192.168.166.1
dns-nameservers 8.8.8.8
dns-nameservers 202.106.0.20
# 重启网卡
ip addr flush dev ens33 && /etc/init.d/networking restart

2.制作本地下载源

# 如果服务器不能访问外网,那就配一个ISO下载源
mount /dev/sr0 /media/cdrom
apt-cdrom -m -d /media/cdrom/ add
apt update

3.工作内容小结

# mysql输出总会提示不要用明文的密码,下面这两行可以让其静默
export MYSQL_PWD=$passwd
mysql -u$user -e "USE IM_CONFIG;DELETE FROM CEMS_SERVER where os='linux';" -A -N
# MySQL初始化语句
/data/linkdood/im/soft/mysql/bin/mysqld --initialize  --user=mysql \
--basedir=/data/linkdood/im/soft/mysql --datadir=/data/linkdood/data/mysql/data \
> /data/linkdood/im/soft/mysql/mysql_passwd.log 2>&1
# 在脚本中向MySQL插入数据
mysql -uzbqltest -p'bUj7Rxz#kwrM(alW' -e "USE IM_CONFIG;INSERT INTO CEMS_SERVER VALUES ('',...);"
# FastDFS启动
/usr/bin/fdfs_trackerd /etc/fdfs/tracker.conf start
/usr/bin/fdfs_storaged /etc/fdfs/storage.conf start
/usr/sbin/ntpdate time1.aliyun.com

# 配置文件检测命令
/sbin/nginx -t -c /data/linkdood/im/soft/nginx/conf/nginx.conf
# nginx启动命令
/sbin/nginx -p /data/linkdood/im/soft/nginx

# java服务能启动做了两步,
往/usr/lib下考了个libtched.so
在${JAVA_HOME}/jre/lib/ext目录下放入vsf-codec-1.0-SNAPSHOT.jar
还有依赖关系需要考虑,config和dbconfig等如果启动时间过长,其他服务也会无法启动

# 解决没有sqlhandler的问题
export PATH=$PATH:/data/linkdood/im/soft/mysql/bin
yum install gcc libffi-devel python-devel openssl-devel
pip install MySQL-python==1.2.5

4.匹配ip

grep -E "[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}" a.txt
sed -r "s#(\b[0-9]{1,3}.){3}[0-9]{1,3}\b#${IP}#g" a.txt
sed -r "s#([0-9]{1,3}.){3}[0-9]{1,3}#${IP}#g" a.txt

5./etc/profile示例

export MYSQL_HOME=/data/linkdood/im/soft/mysql/bin
export JAVA_HOME=/usr/java/jdk1.8.0_191
export PATH=$JAVA_HOME/bin:$MYSQL_HOME:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export JRE_HOME=$JAVA_HOME/jre
export LD_LIBRARY_PATH=/usr/local/lib/
ulimit -SHn 999999
ulimit -c 999999
