I am a linux operation and maintenance engineers, a Michael Kors Bedford Logo Medium Brown Satchels little experience in this area, and now I want to talk about what aspects of the tool to grasp it comes to tools, skill-row can be said that, within the line we generally called tools, operation and maintenance that must be mastered tool. I'll probably listed these areas, so the entry basically no problem. linux system is to learn if you can use redhat or centos, centos especially in the enterprise with the most, of course, there will be other versions, but the learner is to learn these two versions on the line, because both versions are brothers, no difference, the time can then look at SUSE, some companies like to use, for example, my company. ʱ?? ʱ?? ʱ?? ʱ?? Tools as follows: 1, linux-based system, it goes without saying, is Michael Kors Bedford Logo Large Pink Crossbody Bags the basis of this foundation, even this will not be done on the other, reference books, watch Bird Brother linux Basics, at least 60% to master the contents of this book, did not have full control, but the Michael Michael Kors Berkley Logo Large Black Clutches Kors Bedford Logo Large Purple Crossbody Bags basic command gotta be it 2, network services, there are many services, each company will be used in a different, but certainly to master basic services, such as FTP, DNS, SAMBA, e-mail, these probably learn on the line, LAMP and LNMP must be skilled, I mean would not bare to build, but to be quite familiar with the configuration inside job, because the company is Michael Kors Bedford Logo Monogram Large Black Totes absolutely the most critical WEB server, nginx and apache to familiar, especially nginx must be very Michael Kors Clutches familiar with the job, at least some companies will use tomcat, it's best to learn about this. In fact, network services, do not worry too much, general corporate environment have to build a good, even if there is a new server or let you rectification, the company will let you reference the appropriate documentation to get, will not let you fool around, Michael Kors Bedford Gusset Medium Tan Crossbody Bags but at least the relevant Configuration must learn cooked, and certainly more than compile and install those modules you want to familiarize yourself with his role, especially those PHP module. 2:00 This is a basic side, but also a necessary condition, can not be said Tools, with real tools to master. 3, shell scripts, and other scripting languages, shell is the operation and maintenance personnel must have, do not understand this even entry will not, at least write some system administration scripts, the easiest have to write a monitor CPU, memory ratios script Come on, this is the most basic, do not think and calculate the write Guess what number of those, these little effect, meaning only for learning, writing system script is the most meaningful, while another script language is optional generally 3P, ie python, perl and php, php you do not need to consider, unless you want to do development, I suggest it would be better to learn python, difficult to automate the operation and maintenance, perl is very powerful text processing, anyway, two a-school on the list. 4, sed and awk tools Michael Kors Bedford Logo Monogram Large Coffee Totes must be mastered, mastered these two tools Michael Kors Bedford Logo Large Black Crossbody Bags at the same time, but also master the regular expression, this is painful, the regular expression is difficult to learn, but the combination of the sed and awk will be very strong very useful when working with text content and WEB content filtering, but at the same time learn shell generally often used in combination, so learn Michael Kors Berkley Logo Large Beige Clutches point 3 point 4 will be the way to school. 5, text processing commands, sort, tr, cut, paste, uniq, tee, etc., will learn, also point 3 when combined together learning. 6, the database, the preferred mysql, do not ask me why not learn sqlserver and oracle, because linux is absolutely the Michael Kors Berkley Logo Large Black Clutches most used mysql, CRUD will learn, especially to learn cooked investigation, other aspects may not be needed because the operation and maintenance personnel Up or investigation, optimization and development which will not let you get the statement. 7, firewall, not to learn not, the firewall can be difficult, that is hard to say easy to difficult, the most important to understand the rules, if CCNA learned friends may be more eager to learn, because there are iptables NAT table, the principle is the same while FILTER table with the most, but do not learn certainly failed. 8, monitoring tools, very, very important, I suggest, is best learned that three, cacti, nagios, zibbix, companies with the most should be the nagios and zibbix, anyway, for it, but nagios will be a little difficult, because it will involve Michael Kors Berkley Logo Large Black Clutches to write a script to automatically monitor, that place is difficult. 9, clustering and hot standby, this is very important, be sure to understand, but the company will not let you go and get, because basically will not let you touch the novice, there are many cluster tools, the best science is LVS, it is necessary to learn , it is best to learn nginx cluster, reverse proxy, as well as hot standby, this tool can achieve even more, like my Michael Kors Bedford Signature Large White Totes Michael Kors Bedford Logo Medium Black Satchels own development company is hot backup tools, mysql hot standby have to learn, it is a master-slave replication, Do not tell me this is easy, in fact, not easy to learn to understand the whole process is not easy, just simply do not intend to follow suit. 10, data backup, do not learn Michael Kors Outlet no, there are a lot of tools, but the principle should at least understand the RAID, especially is the most commonly used 1 + 0 or 0 + 1, do their own experiments have to get out, there are a lot of backup tools, such as tar, dump, rsync, etc., it is best to know more about. Well, at this point 10:00 has suffered enough for you, you should be able to entry, because it would be more difficult to learn some techniques, such as apache and nginx are also some very important technology, such as system tuning and optimization services, as well as program optimization, which before had not been contacted to work hard to learn, so that 10:00 first learn it, is estimated to learn at least three months more than ripe, it has been part of the script that makes you very difficult, I would suggest is to first learn cooked shell, etc. and then learn another scripting language, this would be better. These are the linux into operation and maintenance engineers need to have the tools, there are also a lot of tools to master, but you are in a learning environment is difficult to learn, finally, I again remind you, the tool referred to here is equivalent skills, not like those windows or ubuntu graphical tools, those tools useless, as well, do not learn linux install a graphical interface, so do not eat too much virtual machine memory, and certainly do not recommend real machine tops linux, impossible to achieve without to learning.Linux entry operation and maintenance engineers must master the 10 technical points
